Oct. 10, 2017	Brent Butterworth Senior contributor, SOUNDSTAGE!		I got a surprise when I stumbled on M&O Electronics, tucked away in one of the ground-floor hallways of the Marriott. The company’s MOOH-BE00BT Beryllium Acoustic Bluetooth headphones ($129) use a generic design with a beryllium-diaphragm driver; I was thrilled at the plush comfort of the earpads and the spacious sound and natural tonality of the MOOH-BE00BTs.

Dec. 22, 2017	Pinky Powers Author, THL		The M&O Beryllium Acoustic Bluetooth Headphone conveys a warm, rich character. A friendly, organic sound is the intent, while notions of detail, resolution and analysis are left behind. Bass is front and center in the tuning. It’s elevated a good bit, both sub-bass and mid-bass. We’re not talking basshead levels here, but there’s certainly a healthy amount. Texture and rumble are in abundance. Deep lows imbue your music with a visceral punch. There’s a size and dimensionality to MOOH’s bass you don’t hear in many cans. It’s delightful. Vocals are colored by the bass, though not to the extent where details smear too much. MOOH’s mids have lushness to them, warm and smooth. They exist slightly behind the bass, lacking clarity. What you get in trade is great note weight and authority. Make no mistake, they sound engaging, fun, and natural enough. Treble is the least noteworthy thing about the M&O. It sits below the mids, and well below the bass. There’s just barely enough to hold back the tides of darkness from all that low-end. MOOH’s high frequencies possess quite a helping of warmth, making for a velvety, easy listen. MOOH is a safe headphone for those worried about treble fatigue and harshness. However, unlike the bass, I don’t feel the treble enjoys great extension. It sounds like it rolls off pretty drastically, taking away air and natural sparkle. In fact, the upper registers come off unnatural, truth be told. If it weren’t for these highs, one could forget they were listening to such inexpensive gear. But instead, they cast a kind of cheapness over the whole production which keeps MOOH from excelling beyond its price point. The simplicity of charm. It is easy on the ears, and has such qualities as to sweep you up into its rich, warm tonality. While it is not a technical marvel, I find it impossible not to like what I hear. If you love your music dark-sounding, and seek an inexpensive set of Bluetooth cans, I gladly recommend the MOOH-BE00BT. They will envelope you, as you relax into their cozy depths.

Dec. 26, 2017	Kman1211 Audiophile, HF reviewer		Now let's talk about the bass on this headphone. No need to hide this, this headphone packs a punch. The bass slam on this headphone is incredible and it does have a bit of a bass emphasis, the interesting thing is it doesn't really bleed into the mids at all, this isn't a mushy bloomy bass, this is a tight, clean, and impactful bass. This headphone definitely satisfies my inner bass-head. I started this hobby as a bit of a bass-head, some of that still remains. EDM listeners will love this headphone. Some people may find the bass a bit too much though. Now let's talk about the midrange, how does it fare? The midrange is actually quite good, it has good dynamics and is present enough where I don't feel anything is missing or recessed, more akin to the subtle u-shaped curve you find in many Beyerdynamics where everything is clearly audible but it takes a slight step back. The mids are pretty much where they need to be. Vocals come off as clean and clear to my ears and are pleasantly full and present. The headphone is a bit sweet and musical sounding in the vocals and mids to my ears. This is where most headphones struggle in my experience, especially at lower price ranges. Does this headphone manage to do treble well? Yes I would say it does, it's clean and non-fatiguing and isn't what I would call too bright. There does seem to be a slight edge and brightness in the treble but nothing that is bothersome to me personally. The treble is clear, articulate, and seems to extend quite well, I don't find myself wanting for more or less treble and the treble has good dynamics to it. This is the first headphone I've heard below the $200 mark other than the HD 6XX that I found the treble or upper mids wasn't an issue in regards to fatigue. Overall I rate these headphones very highly, I don't give 5 star reviews lightly, but this headphone gets one from me due to it's excellent sound, good comfort, and value plus the added benefit of wireless functionality with excellent battery life. To my ears this is the best sounding closed-back that can be had for under $200 and honestly competes with more expensive headphones. Tuning wise this headphone will be better suited for people who like a punchy and strong bass and lively dynamics. Regardless of the tuning the actual quality of sound is excellent, I see a lot of pad rolling potential with these. In conclusion, I highly recommend these headphones on their sound quality alone, the wireless is just the icing on the cake. If your looking for a good portable and wireless headphone under $200, I'd say look no further.

Feb. 16, 2018	George Dobrescu Editor, HF reviewer		When it comes to their sound quality, this is the reason they have been used every day. First, let's start with the Bass. Then there comes the bass. And lastly, the bass. Don't misunderstand my words, those headphones aren't basshead headphones necessarily, but they have an amazing bass, with excellent textures, quantity of bass, and extremely nice rumble and tactile feeling to it. The bass extends quite low, with nice depth to the sub-bass and with an interesting presentation. The midrange is organic and sweet, being colored by the bass into having good weight to each musical note, and quite a nice engaging presence. They are quite natural and the whole midrange is quite enjoyable in the long run, but it isn't the clearest out there, being rather warm and a bit crowded. The general tonality can be dark and laid back, especially when compared to a true neutral headphone / IEM. The treble is recessed when compared to the midrange and the bass, posing a little issue for those seeking the ultimate clarity, as it rolls off considerably early, and provides a rather limited listening experience for rock and metal music, which relies quite a lot on cymbals and cymbal energy. It should be noted that the treble reaches around 9-10kHz. We tried to Equalize the treble, but playing with the 16 kHz slider on our EQ makes only a small a difference, and the 8kHz slider on our EQ makes a larger difference, but it makes the treble a bit hot if enhancing it too much, the treble smoothness / roll-off not being equalizable.

Feb. 21, 2018	Pan_DAC Audiophile, HF reviewer		It sound great for a Bluetooth headphone. It has a warm and rich sound, with a smooth top end. The bass is strong and has a nice thump to it, making it good for EDM or dubstep, but not overbloated or boomy. The midrange is clear and pretty much perfect in terms of placement. Its not too recessed and not too forward. Vocals come in clear and with detail without being shouty or sibilant. Treble is nice and smooth, perfect for people who can sensitive to higher frequencies, and it has some detail and air, but not a whole lot, and this would be my only complaint...

Feb. 22, 2018	Steve Guttenberg Audiophiliac, Audio journalist,		This $129 Bluetooth headphone delights the Audiophiliac. The M&O Electronics MOOH-BE00BT Beryllium Acoustic Bluetooth headphone somehow won over the hard to please Audiophiliac. Now that I've spent some time with the MOOH-BE00BT I'd describe its sound as "dark" and lacking in detail, but I think that's a plus for an affordable BT headphone. The sound is non-fatiguing, and easy to listen to for hours at a time. Nothing about the MOOH-BE00BT's sound started to annoy or detract from the job at hand, listening to music. So while it's not going to satisfy folks yearning for maximum resolution or detail it's a nicely made, $129 Bluetooth headphone. https://youtu.be/WH_vxTlnbQE

Mar. 14, 2018	Frank Iacone Editor-in-Chief		The $129 M&O was astonishing, the sound was anything but inexpensive, and the transparency blew me away. The sound had terrific balance and was detailed while being musical. Bowei Zhao is doing a full review on this amazing headphone that is high end sound at a ridiculous low price. Predictions can be tricky, but I feel so confident after listening to this little wonder that M&O will take the industry by storm. Offering exceptional quality at a price everyone can afford.

Mar. 23, 2018	Hifitr5_wp Editor, HF reviewer		I compared it to my favorite Bluetooth headphone in the $100-$150 range, the AKG Y50BT, and while it had more top end detail and better controlled deeper bass, I actually preferred the more forward midrange of the M&O headphones. The AKG was a more lively listen overall, with more sparkle in the highs, and deeper, more detailed bass, but the sweeter mids of the MOOH-BE00BT headphones made me want to listen to them longer. Neither had much in the way of separation or imaging, but I find that par for the course at this price level. The mids of the M&O product made them sound a tad bit more open than the AKG, and it presented a decent soundstage for a headphone. When I connected the MOOH-BE00BT to my phone using the wired connection and turned on the LG V30’s Quad SABRE DAC, the sound got a little better, with the veil lifting a bit, and the bass getting tighter. The treble also seemed to be a little bit more prominent. In the wired mode, I would say they actually sounded quite neutral, probably due to the absence of coloration from the bottom end. They still lacked much separation between instruments, but I enjoyed the slightly higher resolution.

Apr. 05, 2018	Bowei Zhao audio Guru		I started off the MOZero with one of my favorite songs, “Flower Dance” by DJ Okawari from his smash album Kaleidoscope. It’s an instrumental song with a mix of piano, backing percussion, and string instruments formulated to become an undeniably solemn journey into melancholy before a final eruption into hope for some distant future. The MOZero reproduced the piano well and provided a comprehensive performance. The piano was slightly pulled back while the percussion thundered on in the track. Unexpectedly, the high frequency range was better than expected when the chimes were struck providing a 3D effect with a clear high frequency reproduction across the top of my head. An audiophile review isn’t finished without some Fleetwood Mac! Here we have “Sisters of the Moon – 2015 Remastered” from their album Tusk which as always has fantastic mastering and instrument separation. I’ve typically found ‘consumer’ headphones to always do well in mainstream music but fall apart once good quality tracks are thrown their way. The MOZero was the opposite! It was able to scale well to better quality songs and it’s here that I had the best time listening to the MO. The backing instruments and the separation between them was reproduced smoothly, leaving us with exceptional string instruments that can be heard in each ear like angels playing a harp as you sleep. The vocals in this track by Stevie Nicks were much more forward than I was expecting (which is great) and had a throaty undertone to it. What’s more, the speed and robustness of its beryllium drivers are really brought up to the light in this song; it simply kept up with every demanding sequence. I was very pleased with the sound of the MOZero. I was critical of some aspects of the headphone above because again, it really isn’t an audiophile headphone. The MOZero is a headphone that reacts to every genre with ease as it pummels through each segment without fatigue or offense. It has a dark and laid back sound that should please any listener as they take this headphone out with them on the go.

Oct. 08, 2017	Dr. Hammock First customer		Was at RMAF17 and met Dr. Wang and heard these headphones. Lightweight and comfortable, yet still maintained a firm fit. Frequency response, from top to bottom, was very even , with no undue emphasis on any range. Smooth and detailed, never fatiguing. Highly recommended!

so far	Amazon Customers Eight 5 stars / eleven reviews		Mountainman: Oh my word these are really great! Perfect for extracting the maximum sound quality you can get out of your phone. I find it humorous that some people spend hundreds and hundreds of dollars on headphones for their phones... I mean, you are limited by your lowest common denominator. For most people, that is the music streaming through their phones... Ugh! But these headphones do compete well with others that cost three or four times what these cost (probably even more). I don't know how they supply such great sound at this price... S2kPanda: Sound: 6/5 - The most important part of a headphone review... how does a headphone score an extra point on a 5 point scale? I'll tell you that out of the box these headphones sound spectacular for their price. PACsman: Best Bluetooth sound quality I have heard! Layered sound! I didn't know Bluetooth could deliver layered sound! Bose, Sennheiser, Sony, B&O, Bowers and Wilkins, and other's don't provide any sound detail. M&O does! S. Riley: A Great price performance Bluetooth headphone InvoluntarySoul: Supreme bass, detailed mids and rolled off highs, I find this signature very enjoyable and non fatiguing Akhilesh Bjaj: Superbly designed device that improves your life significantly. My strongest recommendation. Silver: The highs are crisp and don't drowned out by the super clear mids. Regina Hammock: Smooth and detailed, never fatiguing. Highly recommended!
