PowerBass SoundTube BT-500 Waterproof Bluetooth Speaker Review

One thing I like about electronics is their constant evolving. I love my music, and always take it with me. Wireless speakers are getting better with more features. That’s the case with the PowerBass SoundTube BT-500. It's a wireless speaker shaped like a boombox and is loaded with features.  Yet MSRP is only $149.

 

Features and specs:

Waterproof design IPX7

Bluetooth 5.3 Chip provides 30Ft. of wireless range

RGB Lighting with User Selectable Effects

User Selectable Equalizer

USB-A for use with Thumb Drive Music Storage

USB-A for charging mobile devices

Built in Microphone for handsfree calling

3600mAh Rechargeable Battery provides 7 hours of music playback

TWS True Wireless Stereo – connect 2 BT-500 Tubes together for true wireless stereo sound

Shoulder Strap for easy carry

USB-C Charge Cable included

 

The PowerBass Sound Tube BT-500 came in a nice-looking color printed box with photos and specs. Opening the box revealed a well-protected speaker held in place by custom molded foam. Materials used in the construction was mostly plastic with some metal, cloth and rubber. Quality of materials used, as well as fit and finish was very good. Also included was the charging cable and shoulder strap.

 

I’m very impressed with the design of the PowerBass Soundtube BT-500. To start you get features that are common for these wireless speakers. There’s Bluetooth 5.3, IPX6 water resistance, and 3.5mm aux-in port. Also as is found on a lot of newer wireless speaker designs, there’s also a built-in rechargeable battery (7200 mah) that can also be used as a power bank to charge your smartphone.

 

PowerBass did not stop there. There are passive radiators on both sides for improved bass response. The passive radiators also light up with RGB’s that dance – very cool. There’s even a built-in mic so you can use it for hands free calls. One of the coolest features though is it’s TWS, for True Wireless Stereo. Linking two of them together, they act like a pair of stereo speakers. They don’t get extremely loud. So if you have a larger get together, having two of them would double the sound. Being able to have stereo sound is an added bonus that improves the sound, very, very cool!

 

PowerBass also did not ignore the styling, which also helps its functionality. I love the black cloth that wraps around the front and back to give it an elegant look. The buttons are all on the top and are easy to use. There are rubber feet on the bottom to help stabilize it. The ports on the back are behind a rubber cover for water resistance. The handle on top is well made and feels durable for ease of carrying it around. And on both sides of the top is a metal re-enforced slot for the should strap.

 

The PowerBass Soundtube BT-500 is a great example of how all the parts came together for a great product. The contacts and connections are well placed for ease of use. The handle and carry strap slots are strong for a lot of use. The black cloth that wraps around the front and back covering the two tweeters and two woofers give an elegant look. And the two passive radiators improve the bass output. It comes together well, let’s see how it sounds.

 

Jessie J, Ariana Grande, & Nicki Minaj: Bang Bang – snare drum and toms, had great dynamics and pitch definition of the pad and midbass. Kick drum also was dynamic with good low-end extension. I was very impressed with the resolution of the drums. Bass beats also had good output and depth. But it was the aural feast of the vocals that stole the show. The various vocal parts were so clean with amazing harmonics that gave me goosebumps.

Nat King Cole: L-O-V-E – cymbals and hi-hat was really crisp and clean. Piano sounded very natural. The bass had good smoothness of the strings with good low-end extension and output. Violin strings were also smooth. Vocals had very good resolution of the texture of the timbre. Trumpet and trombone were both really clean with great dynamics and harmonics. I also wasn’t expecting this good of imaging, and a sound stage that was fairly deep.

Tiesto & Sevenn: Boom – a good bass torture track. I was impressed with what it did, and didn’t do. Bass beats were dynamic, clean and good output. It also didn’t try to play what it couldn’t play, which would have been muddy and distorted.

 

The True Wireless Stereo feature is really cool! The user manual was worded very well and easy to follow. So entering that mode was really easy. Once activated, one did function as the left speaker and the other was the right speaker. While the imaging in TWS mode was not as good as a traditional pair of wired stereo speakers, it still did sound really good. It was quite amazing actually.

 

There’s a lot to like about the PowerBass Soundtube BT-500. It’s not only a well-made wireless speaker with a lot of features that’s easy to carry around. It also sounds really good. If you’re looking for a wireless speaker, it deserves to be on your short list. Especially with its low $149 MSRP. That’s a huge band for the buck! Based on its design, features, quality and performance. The PowerBass Soundtube BT-500 has earned our Editor’s Choice Award.

2025 Annual Holiday Gadget Gift Guide

It’s that time of year again. Halloween is over, and November is here.  Which means that it’s also time for our annual Holiday Gadget Gift Guide.  Some family and loved ones are easy to shop for, and for others we need a little help.  Hopefully we can provide some assistance with that.  Below are products that could be a great gift, with their description of what they are and a link to the review or the schedule when to come back for the review.

 

Family and friends are an important part of our lives.  If you like to entertain, music is an important part of the party.  And sometimes a small Bluetooth speaker just won’t cut it.  You need something bigger for those outdoor venues and when there are a lot of people involved.  The Fender X Teufel Rockstar Air 2 could be exactly what you need.  Check out its review here:

https://www.stereowiseplus.com/2025/03/fender-x-teufel-rockster-air-2-hi-end.html

 

Life can be stressful. Somehow, music can help with that.  And if your car speakers are either starting to fail, or don’t sound as good as you would like, it could be time for a replacement.  Harman Kardon has a great sounding direct fit factory speaker replacement in their FIT6CF and FIT6F. It could be just the thing to put a smile on the face of a loved one. Check out its review here:

https://www.stereowiseplus.com/2025/07/car-factory-speakers-upgrade-featuring.html

 

Electronics has found its way into a lot of the products we use.  Even with gun safes, many use biometrics for ease of access.  The Headrest Company, has brought that feature into a gun safe for our vehicles.  Now you have a nice safe that is well hidden, that can be used for a gun or any other valuables.  Check back here for the review scheduled for the week ending 12/14/25.

 

There’s a lot of bass heads out there.  I like a lot of bass myself, especially in my car.  But sometimes you may not have much space for a subwoofer.  If you have a loved one who is always using their trunk, but would love to be able to have more bass, Infinity can help.  The Infinity Reference 1000SSL 10-inch car passive subwoofer with passive radiator could put a big smile on their face. Check out its review here:

I like to take my music on the go.  Whether its by the pool, or up in the mountains while camping, JBL has a wireless speaker for you.  One of their biggest of portables is the JBL Boombox 3.  It plays loud, but is also waterproof.  So no matter the location or weather, your tunes can continue.  If you have a loved one who enjoys the same, this could be perfect for them.  Check out the review here:

https://www.stereowiseplus.com/2025/09/jbl-boombox-3-bluetooth-speaker-review.html

 

I love my music.  But not only that, I like it loud!  If you have a loved one who fits that bill, their factory car radio may not be providing the power their speakers need.  In this scenario, a separate amplifier could be what’s needed.  JBL makes a great one with their JBL Club A758 High Performance Class D 8 Channel Car Amplifier.  Check out its review here:

https://www.stereowiseplus.com/2025/03/jbl-club-a758-high-performance-class-d.html

 

PowerBass is known for their subwoofers, but they also have a great portable boombox.  It’s smaller, yet is till big on sound.  With its passive radiators it even provides good bass.  The waterproof feature makes it easy to take anywhere. Add to it the built-in power bank feature, and it has excellent usability.  You can even link two of them together for true wireless stereo sound.  Check back here for the review scheduled for the week ending 11/30/25.

 

For many decades, we have gotten accustomed to electricity.  It powers just about everything. But there are times when the power does go out.  Many of us may not think about it, but there are a lot of preppers that do.  If you know someone who falls into that group, the Romoss X1000 Portable Power Station and BE1000 Expansion Battery Pack could be perfect for them.  Check out its review here:

https://www.stereowiseplus.com/2025/02/ramoss-x1000-portable-power-station-and.html

 

Many of us like a lot of bass in our music.  And then, some people can take that love for bass to a whole new level of loud!  All that bass requires a lot of power, and many amps aren’t up to the task.  If you have a loved one who would love more sub power, Sundown Audio has the answer in their SALT-2 sub amp.  Its review is found here:

https://www.stereowiseplus.com/2025/07/sundown-audio-salt-2-subwoofer-amp.html

 

Music is not always about the bass.  Some of us like all of the sound really loud.  If your loved one likes premium sound quality, but also play it loud enough so everyone around can also enjoy it, Sundown Audio has a solution.  It’s a great sounding factory speaker system replacement that not only sounds great, it does so while playing really loud.  Its their SA-6.5CXv2 and SA-6.5CSv3 factory upgrade speaker system.  Check out its review here:

https://www.stereowiseplus.com/2025/10/sundown-audio-sa-65csv3-2-way-component.html

 

So many of us do a lot of shopping on Amazon.  Package deliveries are getting much more popular.  Whether you want to see who is at your door, or you want to watch over packages that were delivered, a video doorbell could be just what your loved one could use.  And the Swann SwannBuddy 4K Video Doorbell could be the perfect solution.  Check out its review here:

https://www.stereowiseplus.com/2025/03/swann-swannbuddy4k-video-doorbell-review.html

 

Torras Coolify Cyber Neck Air Conditioner.  Just as the product name states, it’s a portable air conditioner that you wear around your neck.  It provides heat in the winter, cold air in the summer, or a fan for those slightly warm periods.  If you know someone who loves to travel, this could be perfect for them.  After all, the weather at some of our planned destinations could be less than ideal for us. Check out the review here:

https://www.stereowiseplus.com/2025/02/torras-coolify-cyber-neck-air.html

 

Smart Watches are getting more and more popular.  They do so much for us.  Sometimes you’re busy and can’t answer a text or phone call.  But just a glance at your watch could tell you if it’s something that can’t wait.  But some of these smart watches aren’t very dressy.  The Withings ScanWatch Nova Brilliant is a really classy looking dress watch, but manages to also have a digital display on the face.  It even has medical grade sensors.  It could be a perfect gift for that loved one who likes to look sharp.  Check out its review here:

https://www.stereowiseplus.com/2025/05/withings-scanwatch-nova-brilliant.html

 

 

We tried really hard to give you a good variety of products in our gift guide.  Not everyone is the same.  And they all are well made products that give great functionality.  We hope we gave you some good gift ideas for your loved ones.  And from our family to yours, Happy Holidays!

Sundown Audio SA-6.5CSv3 2-way Component and SA-6.5CX Coaxial Premium Factory Speaker System Upgrade Review

We all like our tunes, especially in our rides. Unfortunately, those factory speakers in most cars, are lacking. It’s basically planned obsolescence. So whether the days of your factory speakers are over, or you just want a serious upgrade, it’s time to replace them. There’s lots of options for you. You could go basic, high quality, or premium. We previously covered a high quality upgrade system from Harmon Kardan. This is part two of our upgrade review, and features Sundown Audio. It’s their SA-6.5CSv3 2-way components for the front, and SA-6.5CXv2 co-axial for the rear. MSRP is $399 and $199.

 

Features and specs:

SA-6.5CXv2:

120 watts RMS

Silk dome tweeter

Hybrid fiber cone

Adjustable crossover - midrange and tweeter

Cast aluminum frame

Magnet ID shorting ring (midrange)

Machined aluminum tweeter housing 

High-compliance rubber surround

2.75" DEPTH

 

SA-6.5CSv3:

6.5" Component Speakers System

125 Watts / Side

Silk Dome Tweeter

Machine Aluminum Tweeter Housing

Case Aluminum Frame

Magnet ID Shorting Ring (Midrange)

Carbon Fiber Cone

Rubber Surround

24dB/Octave Crossover

Adjustable Tweeter Level (-3, 0, +3)

Mounting Depth: 2.87"

Cutout: 5.63"

 

 

Both the Sundown Audio SA-6.5CXv2 and SA-6.5CSv3 came in a nice color printed box with specs printed on the box. Opening the box revealed a well-protected speaker held in place by custom molded foam. Materials used in the construction was mostly metal with some plastic, rubber, and hybrid fiber cone. Quality of materials used as well as fit and finish, was excellent. Included was woofer with built-in tweeter for the coaxial, separate woofer and tweeter and passive crossovers, for the component system, as well as wiring and screws for mounting.

 

As I mentioned before, most factory speakers are less desirable. They sound just ok and are usually made with thin paper cones and thin surround that won’t last long term. Hence the planned obsolescence. Most aftermarket speakers tend to be cheap, using a lot of plastic and stamped baskets. Some companies spend a lot of time developing a better-quality speaker with better sound, yet still cut some corners to save costs, such as using stamped baskets. With premium speakers you get superior build quality as well as superior sound.

 

I love the design of the Sundown Audio SA series speakers. Having been in business for almost 20 years, most of it building premium subwoofers. They used this experience for premium coaxial and component speakers, such as using an extended pole piece to allow for more excursion. For cooling there is a vented voice coil collar and vented magnetic gap. Having 6mm of linear one-way excursion and the extra venting translates into higher power handling. The employment of the blend of paper and wool fibers assist in damping any unwanted resonances, as does the rubber surround. Depending on where you cross over the midrange, they can handle 60-125+ watts RMS.

 

To mate well with the midrange, they paid a lot of attention on the tweeter. A silk dome is used for similar smoothness of sound. Then there’s the passive crossover. To maintain the high sound quality goal, they used high quality air core inductors and mylar capacitors. The end result yields a very well-made product for great SQ. And the crossover even allows for CPF slope as well as tweeter slope. Now let’s see how they sound.

 

Earth, Wind & Fire: September – shaker sounded really crisp, wood block had really nice woodiness to the tone. Trumpet was really clean with excellent harmonics. Cymbal was equally really crisp and clean. Vocals had excellent resolution of the texture of the timbre. Drums were really dynamic with nice low-end extension.

Disturbed: Sound of Silance – Piano sounded really natural with very nice harmonics. Vocals were extremely crisp with excellent texture of the timbre. Strings were equally as crisp with nice resolution of the decay of the strings.

Nat King Cole: L-O-V-E – cymbals and high-hat were really crisp and clean, piano sounded very natural with good resolution of the strings. Strings also were silky smooth with very nice resolution of the bass. Trumpet was not only equally smooth, but also extremely dynamic with excellent harmonics. Vocals were smooth like honey with equally excellent resolution of the timbre. Soundstage was also very deep and wide, with imaging on a dime.

 

In contrast during the installation, I inspected the stock speakers in the older 2004 Toyota Rav4 when they were taken out.  I was shocked that they weren’t blown, especially with their thin cones and surrounds. The person I got it from must have never used the stereo. And their magnet was so so small, I’m surprised the speakers sounded as good as they did.  But don’t take that the wrong way.  Out of 10 I would give them a 4, but with the magnet as small as it was, I’m surprised they weren’t a 3.  And the plastic tweeter was equally unimpressive.  While you could hear the music, that’s the best I could give them. It was like listening to qood speakers with thick earmuffs on. You could hear the music, but it sounded extremely thin, flat, hardly any resolution or highs.   The Sundown Audio was a night and day difference, like a revelation.

 

Not only does the Sundown Audio SA-6.5CXv2 and SA6.5CSv3 designed to handle a lot of power, they also sound great doing it. And thanks to the excellent build quality, they should have you rocking for years. If you want to take the sound in your ride to a whole new level, the Sundown SA6.5CXv2 and SA6.5CSv3 should be on your short list. Based on their design, features, quality and performance, they have earned our Editor’s Choice Award. For more info and complete specs, check out their website at www.sundownaudio.com.

New Campfire Audio DAC Wallet & Time Link cable are the must-have accessories for portable audio listening

 

Portland, Oregon, September 23rd–– Campfire Audio has announced two new accessories to enhance your portable listening life: the Portable DAC Wallet to keep things looking neat and sounding great, and the Time Link cable to quickly adapt your earphones to suit a range of devices (and provide an in-line USB DAC, too).

 

The DAC backpack for your phone
​Crafted from leather, the Campfire Audio Portable DAC Wallet magnetically attaches to your smartphone and snugly holds your choice of sound-boosting DAC. A custom USB-C cable allows you to further reduce the tangle of tech in your pocket and avoids ‘dongle DACs’ dangling precariously on an overlong lead.

 

Portable DAC Wallet

 

As well as being compact, the Portable DAC Wallet’s custom USB-C cable aligns connection points for a lower-profile, reduced-tension fit – minimising the risk of port-wear on either your phone or portable DAC device.

 

The Campfire Audio Portable DAC Wallet is the ideal match for the Campfire Audio Relay DAC but also happily houses a wide range of alternatives. For phones or other portable devices without built-in magnetic support, an optional adhesive magnetic ring is supplied.

 

One cable to rule them all
​Quickly and easily adapt your earphones to suit a range of devices ​ - ​ from smartphone to laptop to digital audio player and more - with the ​ Campfire Audio Time Link cable. Six conductors of high-purity copper and silver-plated copper channel your signal into the swappable termination of your choice, including a powerful, Cirrus Logic, USB-C DAC.

 

Time Link Cable

 

Time Link comes with six conductors (3 x copper; 3 x silver-plated copper) and these swappable terminations: 3.5mm single-ended; 4.4mm balanced; USB-C DAC.

 

Pricing and availability
​The Campfire Audio DAC Wallet + Custom USB-C cable is available now from Amazon and a range of specialist audio retailers, with a suggested retail price of $59.

 

The Campfire Audio Time Link cable is also available now from Amazon and specialist stockists, with an SRP of $299.
