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 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 Amazing value and sounds! 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 Audiophile Heaven 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.

 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!

seven 5 stars / nine reviews

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!
