Materials used in the construction was mostly plastic with some silicone and metal. Quality of materials used, as well as fit and finish, was very good. Also included was the manual.

 

I like the design of the Cleer ARC4. It’s a simple around the ear design that is true wireless. This makes them very simple to put on and take off. They also have some great features, such as Dolby Audio, THX-certified, Hi-Res Audio, IPX7 Water resistance, adaptive voice control, and touch controls. There’s even an app that’s used for sound modes, EQ and media playback. Now let’s see how they sound.

 

Earth, Wind, & Fire: September – texture of the wood block came through very good, snaps and snare drum was dynamic, cymbals and hi-hat was crisp and clean. Kick drum was deep and played with authority. Trumpet was also really clean with very good harmonics. Vocals were silky smooth with good texture of the timbre.

I like the design of the Beyerdynamic Amiron Zero, they are a simple wireless clip-on design that is really easy to use. And the open design makes it easy to hear your surroundings. They also feature IP54 water resistance. There’s also the Beyerdynamic app, which allows you to customize both the sound through the 5 band EQ or the touchpad controls. Now let’s see how they sound.

Now it’s Alclair’s turn with their Alclair UV3 universal in-ear-monitor. Alclair has been in the hearing industry for over 60 years. And they have been manufacturing custom IEMs for over 15 years. While they mostly tailor to the professional musician market with custom IEM’s, they also have a few universal models. Their UV3 is their top of the line universal.

The Alclair UV3 came in a nice color box. Opening the box revealed the well-protected IEM held in place in its hard zipper case. Materials using the construction was mostly plastic. Quality of the materials used, as well as fit and finish, was excellent. Also included were multiple different sized ear tips, and a cleaning tool. There was a QR code on the box to scan for the owner’s manual.

 


I really like the design of the Alclair UV3. It’s a universal IEM, with three balanced armatures. There’s a balanced armature for low, mids, and highs. And I love the clear plastic housing, so you can see all the internal components. And to make sure you get the best fit, there are multiple different sized ear tips. Now let’s see how they sound.

 



Earth, Wind, & Fire: September – texture of the wood block came through very good, snaps and snare drum was very dynamic. Cymbals and hi-hat were really crisp and clean with good resolution of the impact. Kickdrum had really good low-end extension and played with really good authority. Trumpet was also really clean and played with very good harmonics. Vocals were silky smooth with very good texture of their timber.

Guns & Roses: Patience – whistle was smoother than honey, with excellent harmonics, acoustic guitar was really crisp and clean with excellent resolution of the strings and their decay. Vocals were smooth as well with excellent resolution of the texture of the timber.

Brandon Beal: Drop That Booty Down Low – bass beats were tight, clean and played with a ton of authority. And when the booty got dropped down low, it was a whole new level. Not only did the low-end extension go really, really deep, it was like an earthquake in my ears.

 


Now it’s time for the Ultimate Ear’s UE350. Ultimate Ears revolutionized the industry 30 years ago by providing custom IEM’s. Today they continue their legacy, with most of their models being custom models. They do offer a few universal models. The UE350 is the top of their universal models.

I love the design of the ultimate ears UE350. They feature three balanced armatures: a separate tweeter, mid and woofer, along with a passive crossover network. And the housing is clear, so you can look in and see all of the components. While they are universal to fit anyone, they do come with several different sized eartips so you can get the best fit for you. It’s a great design. Now let’s see how they sound.

 

Earth, Wind, & Fire: September – texture of the wood block came through very good, snaps and snare drum was very dynamic.

Brandon Beal: Drop That Booty Down Low – bass beats were tight, clean, and played with good authority. And when the booty got dropped down low, it got even deeper. Not only did they play really deep, they played with even more authority. Oh yeah, it’ll bring a smile to your face.

Materials used in the construction was mostly plastic. Quality of materials used, as well as fit and finish, is excellent.

I love the design of the Shure SE846 Gen 2. It starts with the drivers. You get four balanced armatures in a 3-way design that features a single tweeter, single midrange, and dual woofers. It also incorporates a low-pass filter so you get true subwoofer performance.  With unique nozzles, you can also customize the sound to your liking.  It appears to be a well-designed IEM with game changing features.  Now let’s see how it sounds.

 

Earth, Wind & Fire: September – the texture of the wood block was excellent, snaps and snare drum was very dynamic. Cymbals and hi-hat were extremely crisp and clean with excellent resolution of the impact and decay. Kick drum had low-end extension, dynamics, and played with a ton authority. Trumpet was extremely clean and played with excellent harmonics. Vocals were silky smooth with excellent resolution of the texture of the timbre.

Guns & Roses: Patience – whistle was smoother than honey, with stellar harmonics that was aural bliss. Acoustic guitar was also extremely crisp and clean with excellent resolution of the plucking and decay of the strings. Vocals were also smoother than a Dove bar, with excellent resolution of the texture of the timbre

Brandon Beal: Drop That Booty Down Low – bass beats were tight, clean, and played with a ton of authority. It’ll bring a smile to the face of any basshead like me. But when the booty got dropped down low, it was no joke and definitely sounded like having a subwoofer in your ears! Took things to a whole new level, and it was like an earthquake in my ears. Like the quote from the old 80’s movie, Robocop, “I like it!”

 

As stated in part one of this years annual Headphone Shootout, we also test the Bluetooth range with a torture test. While we have yet to see a headphone not meet the published range, we also like to see what their limits are. So indoors, we test to see how it does between walls on the same floor, as well as between the floors from the basement to the main and second floors. For outdoors, we test it up to 300 feet, now let’s see how they do. The wireless models are the Cleer and Beyerdynamic.

 

Beyerdynamic – no problems in the basement, glitchy on the main floor but useable, a little too glitchy on the 2nd floor to be usable. Outside a little glitchy at 150 ft, usable to 250 ft.

 

Cleer - no problems at all in the basement. Bluetooth connection a little glitchy on the main floor, but usable. Walking up to the 2nd floor, it was too glitchy to be useable. Outside it performed great, with a single glitch at 150 feet, bet then usable out to 300 ft.

 

For the Cleer ARC4, I was impressed at its performance at just $99 MSRP. You don’t get quite the resolution, nor the bass performance with it’s floating over the ear design, as compared to other in-ear traditional designed models. Yet I was still impressed with how well it did sound for its design. Sound signature was mostly neutral, and Bluetooth performance was very good.

 

For the Beyerdynamic Amiron Zero, I was also impressed with its performance at only $179 MSRP. Bluetooth performance didn’t do as well as I had hoped, but it still did better than it’s published range. And it’s wrap around your ear design didn’t quite perform as well as the more traditional in-ear design, it still performed very well. And with the speaker being partly in the ear, it did help with its bass performance. Sound signature was mostly neutral.

 

This was our first experience with Alclair, and we were very impressed. Highs were really crisp and clean, mids were nice and smooth, with excellent clarity in all ranges, with an excellent ability to resolve a lot of instruments without getting bottled down. And the bass response was equally impressive with the same level of detail to make any basshead happy. Overall sound signature was neutral. And I loved the amount of accessories they provided.

 

Next up is the Ultimate Ears UE350. They have a long history of providing excellent IEMs. We have also reviewed multiple of their IEM’s in the past, and I’m glad to see they haven’t’ been sitting on their laurels. Highs were really crisp and clean, mids were also nice and smooth, with very good to excellent resolution provided across all ranges. Low end extension in the bass is also excellent: it goes deep. And the bass output is also really good. Overall sound signature feels just a tad on the bright side. They also give you a great amount of accessories.

 



Last but not least, is the Shure SE846 Gen 2. They have a long history of providing excellent headphones. We’ve reviewed several of theirs as well in the past, and they are always impressive. Yet they have managed to empress me and exceed my high expectations. The highs were so crisp and clean, with pleasantly smooth mids, the level of resolution and detail are a new level. And for the bass, oh snap! That in-line filter they figured out, they must have some Keebler elves working some magic, cause it sounds like there’s a subwoofer in there. Guys, when your girl screams, Yes! Yes! YES! ….You know what I’m talking about. Well, it’s a lot like that. They also provided some excellent accessories. And those actual physical nozzles that you can switch out to change the sound signature? Game changer! While the sound signature is neutral, you can change that to your liking with the filters.

 



We had some excellent products again in this years In-Ear model part of the annual Headphone Shootout. No matter your budget, there are some good options. The Cleer ARC4 provides an easy to wear option, that doesn’t break the bank. The Beyerdynamic Amiron Zero is a bit more, but also provides great wireless performance and for the extra money gives even better sound. But if you can stretch the budget a bit more, both Alclair UV3 and Ultimate Ear UE350 provide monitor level performance. Yet if you can stretch the budget even more, the Shure SE846 Gen 2 are something special, giving more custom IEM level performance in a universal model. Based on their design, features, quality and performance. The Cleer ARC4 has earned our Value award. The Beyerdynamic Amiron Zero has earned our Recommended Award, the Alclair UV3 and Ultimate Ears UE350 our Highly Recommended Award, and the Shure SE846 Gen 2 has earned our Editor’s Choice Award.
