    This review was originally posted on hifitrends.com

    If you say you have never heard of M&O Electronics before, I would surely understand, because I am just making their acquaintance myself. I first heard about the MOOH-BE00BT Beryllium Acoustic Bluetooth Headphone in the Head-Fi forums, and they sounded interesting, so I requested a pair to review.

    M&O graciously offered to send me a pair to check out, in exchange for a fair-minded review. That is what follows.

    The MOOH-BE00BT sells for $129 on Amazon, and its claim to fame is a 45mm diaphragm made with “Beryllium Acoustic Technique” which I can only surmise is a driver made of Beryllium Foil.

    This element has become the material du jour for several new headphones on the market, sourced for its combination of both stiffness and lightness, something highly sought after when designing a diaphragm. This is supposed to allow the driver to move fast with less breakup, thus reproducing the sound spectrum with less distortion.

    Build Quality:

    The MOOH-BE00BT headphones have a rather generic all plastic design, which to me looks a lot like the current Bose Bluetooth headphones, but nowhere near as refined. They will definitely win no design contests. I also wish the light grey logos on the sides of both earcups were a matte finish to blend in with the color of the headphones, or just a tad bit smaller.

    Despite being mostly plastic, they seem pretty sturdy with the exception of the adjustment arms which are pretty thin. However, they are reinforced with a steel headband arch that forms the backbone of the headphone. This spring arch also provides the light clamping force that holds the cans steadily on top of your head.

    Stability is also aided by the plush faux leather earpads which felt very snug yet comfortable around my ears. They also do a very good job of passive noise reduction. When I had them on with music playing, I heard very little going on around me, so they are probably not the best choice for walking around outside. There is also a cushioned faux leather wrap at the top of the headphones, which felt very comfortable resting on top of my head.

    The only issue I had regarding comfort was the heat caused by the big cushioned earpads. If it was the least bit hot when I had them on, my ears sweat like crazy. But that is not isolated to this product, and I still listened to them for hours on end with no major discomfort.

    Features:

    Like I said in the beginning, the MOOH-BE00BT’s main claim to fame is their stated Beryllium Acoustic drivers, which aim to provide a crisp, detailed, sound and they are successful to a point. (I’ll talk more about that in the Sound Quality section)

    They also include support for the apt-X Bluetooth codec, which offers “near CD” quality if your source (most likely a smartphone) supports it, 32 hours of playback time at 80% volume, and supposedly some type of echo cancellation/noise suppression during phone calls. I made a couple of Google Hangouts calls with them and was able to have a conversation without any difficulty on either end.

    Another feature listed on the box is an automatic shut off that kicks in after 5 minutes of no connection to a Bluetooth signal. It worked, but I had to first unpair the headphones using the Bluetooth menu on my phone, completely shutting down the connection to make them do so. When I just stopped playing music and accidentally left them on for about an hour or so, they never shut off. Several of my other Bluetooth headphones will shut off automatically simply by not playing music for a certain period of time.

    This is preferable because most people don’t unpair their headphones from the phone when they are done using them, they usually just turn the headphones off using their on/off button. So if you forget to press the button, and forget to unpair them from the phone, they will just stay on until the battery dies. Or until you walk out of range and the signal disconnects.

    My other bugaboo with these headphones are the controls. They are not intuitive. Three buttons on the right earcup control volume, power, and playback, and since they are all the exact same size and shape, it is very hard to tell which one you are pressing. Several times while using them, I pressed the volume up button trying to press the play/pause button, which was a little annoying. A little bump or indent on the center button which controls the power, Bluetooth pairing, and play/pause would go a long way.

    The other two buttons aligned to the top and bottom of the center button control volume with a single press, and then track forward/back with a press and hold. This double function setup is not my favorite, but the buttons are very responsive and I had no problem switching songs or adjusting the volume.

    As far as accessories go, the MOOH-BE00BT comes with a slim hardshell case that is the perfect shape to slip into most backpacks or messenger bags, a charging cable and a 3.5mm headphone cable for wired operation. The earcups swing in 90 degrees to lay flat in the case, and the case has an elastic band to hold the headphones in. Update: M&O just sent out a warning out to users stating that the elastic band should be cut out of the case since the tightness of the band can cause the hinges to break when inserting or removing the headphones. I didn’t experience this, but if you have a pair that has broken due to this problem, M&O is promising to replace them.

    Bluetooth 4.0 ensures quick pairing, and really good battery life, with a charge lasting for several days as long as you don’t forget to turn them off. If the battery runs out, you can connect the supplied headphone cable to the bottom of the left earcup and use them without batteries. Charging is achieved by plugging the included USB cable into the micro USB port on the bottom of the right earcup next to the control buttons.

    Sound Quality:

    Now let’s talk about the sound, which is decent for the $129 price tag. I have yet to hear a Bluetooth headphone under $150 sound anywhere near world class, and these are no different. However, if you are looking for a budget set of over-ear Bluetooth headphones, these have a warm and friendly sound that lend themselves to long listening sessions.

    I tested them by pairing to my LG V30 smartphone, which is apt-X compatible, and played a combination of Hi-Res music files and Tidal Hi-Fi streams.

    When I listen to headphones, I have a certain sound sig that really appeals to me, and it’s pretty similar to what I listen for in speakers. That is a somewhat open, forward midrange, with a slight bass bump, and slightly rolled off, yet detailed highs. If you have heard the Bowers & Wilkins P7 Wireless, I consider that to be almost the perfect sound sig for Bluetooth Headphones, even though I feel like the bass can be a little bit too lively at times.

    In comparison, the MOOH-BE00BT sounds darker with a soft rolled off treble, and boomy bass, but they are anchored by a warm, sweet midrange. They are a little thick, with a veil across the sound spectrum, but the overall smooth sound makes them very easy to listen to for long periods without fatigue. If you like a really bright, sparkly and forward sound, you may consider the sound to be too dark.

    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.

    Conclusion:

    If you can get past the far from unfashionable, generic look, the MOOH-BE00BT have a comfortable fit and a warm, smooth, fatigue-free sound that’s easy to listen to for long periods of time. It’s a good non-offensive sound which is not the last word in detail, but there is enough there to provide some excitement.

    Great Bluetooth Sound, at an Affordable Price!
    Written by Pan_DAC
    Published Feb 21, 2018
    5.0/5,
    Pros - Comfort, Sound, Warm Presentation, Deep Bass, Clear Mids, Smooth Treble, Great Battery Life, Good Bluetooth Connectivity
    Cons - Treble could be brighter/more detailed for critical listening sessions
    Disclaimer: I would like to start this review by stating that this headphone was given to me at CanJam 2018 for review for free. I would like to thank M&O electronics and Tom Wang for this headphone, I have no affiliation with M&O, and this review will be as non biased as possible, so as to give an honest review about this audio product.

    Now with that out of the way, the M&O Beryllium Acoustic Bluetooth Headphone, or MOZero is a high end Bluetooth headphone currently priced at $129 at the time of writing this review. The headphone comes with a carrying case, charging USB cable, and 3.5mm male to male cable for connecting the headphone through a wired connection to any device with a 3.5mm output.

    Build Quality:
    The headphone is an all black plastic design except for the logo which is grey, and with metal in the slide adjustments. At $129, there is nothing I can really complain about when it comes to build quality, as its made extremely well at this price point and feel like they can take a beating. I would like to see more metal in the build, but for what it is it is very good.

    Comfort:
    I have a very big head, with very big ears, so with both of those factors, finding headphones that are comfortable (and just fit in general) is a bigger challenge for me. I can safely say that for those with giant ass heads out there like myself, this headphone fits, and is very comfortable. The ear pads on the headphone can fit my ear entirely, and there is a good amount of padding in the headband so that I can wear this headphone for hours.

    Bluetooth and Battery Life:
    The Beryllium Acoustic Bluetooth Headphone comes with aptX and has a battery rated to last 32-35 hours. While using the MOZero with Bluetooth, I encountered no hiccups or disconnects and as for battery life, I have used the MOZero in both wired and Bluetooth mode, so I have not fully tested the battery life, but since I have had it to the time of writing this review, I not had to charge the battery, so I would have to say that battery life appears to be strong

    Sound quality:
    Now for the sound part of this review, how does the M&O Beryllium Acoustic Bluetooth Headphone actually sound? 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, as I would like a bit more sparkle and detail, as one of my main headphones is the BeyerDynamic DT-880 so I am more used to a brighter sound signature, although given this is also to be used on the go, it is good that the treble isn't so bright, as when the user turns up the volume the treble won't get piercing to the ears and damage hearing as much. During listening tests I used it in both wired and Bluetooth mode, and both are very good, although I did notice the treble was better when in wired mode, just wanted to point that out.

    Final Thoughts:
    The MOZero ticks almost all the boxes in what I want in a portable headphone. It is comfortable, built well for the price, and sounds very good, although lacking a bit in the detail. This is now my Bluetooth headphone of choice for when I'm out of the house not using IEMs. Great work M&O Electronics.

    MO Electronics - MOOH-BE00BT - Bluetooth Fun

    MOOH-BE00BT, or MZero as we'll name it throughout this review for the sake of being able to write the review, is an amazing headphone at just 130$, which has beryllium drivers, and APT-X Bluetooth abilities.

    Introduction

    MO Electronics, the company behind MZero is not known at all. In fact, I had no idea who they were and what their product was before reading about it and before a company representative approached me. At the moment of writing this review, the official website doesn't look very good, and many artistic assets look quite old and misplaced, so I gathered more information about MO Electronics before I started writing this review.

    I studied their interaction with their customers, and read a lot more about MO Electronics to be able to say that they are a good company with healthy ethics and a good customer support in the long run. It can be hard being a newcomer to the audio industry, but if they keep up the good work, I think MO electronics will be able to gain a lot of traction with audiophiles form all over the world. It should be noted that at this moment you can only buy MZero in USA, and they are not available to the rest of the world, but they have plans on including worldwide shipping soon.

    It should be noted that I have absolutely no affiliation with MO, I am not receiving any incentive for this review or to sweeten things out. This review is not sponsored nor has been paid for by MO or anyone else. I'd like to thank MO for providing the sample for the review. The sample was provided along with MO's request for an honest and unbiased review. This review will be as objective as it is humanly possible, and it reflects my personal experience with MZero / . Every opinion expressed is mine and I stand by it, the purpose of this review is to help those interested in MZero find their next music companion.

    Packaging

    First things first, let's get the packaging out of the way:

    Mzero is packaged nicely in a medium-sized white box, with a beautiful render on the outside. They keep mentioning the fact that they have large beryllium drivers, which is a key to their sound. The main box they ship Mzero in is filled with a nice material to keep them from harm as well.

    The headphones come in a pleather hard carry case, of very good size. It is very ergonomic to keep them in a backpack, while they are in their case. Within the case you can find a proper cable for connecting them to a single-ended 3.5mm source, along with USB cables for charging them. Since MZero are Bluetooth Headphones, you can use them in combination with any Bluetooth capable device, and what is really nice, is that they also work with APT-X capable devices.

    The carrying case is quite nice all-around and it offers enough protection for MZero, and the number of accessories included is enough to make best usage of them. While other headphones also come with spare pads, and other extras, we're talking about a 130$ Headphone, so the number of accessories is more than okay for this price range, many sub 200$ headphones not coming with carry cases and other extras.

    Build Quality/Aesthetics/Fit/Comfort

    MZero comes with a good build quality, being made out of hard plastic, and their are pretty resistant to scratches. They have a nice shape to them, and while they maybe won't catch anyone's eyes with an excentrique look, they won't make anyone dislike them either, having just the right balance of style, playfulness and elegance in their design to balance them. They have the company's logo on the outside, thing which is quite nice, as it has a nice shape and design.

    The cups can move a bit, and they can swivel, thing which is instrumental to their storage. The headband can be adjusted so it better fits the wearer, the headband is padded nicely, and it is quite comfortable, even for long hours of usage.


    The earpads are some of the better pads out there, being quite soft, offering an excellent contact with the ear, being medium in size, and while they don't quite cover my entire ear (I have pretty large ears), they are large enough to feel comfortable. My girl has much better comfort with them than I do, wearing them for hours each day. I am most intrigued with how soft and nice to the touch those pads feel, being better than any pads I had in this price range.

    The build quality seems pretty stable, they don't creak after usage, and I can't say I noticed any wear on them after two months or so. The pads didn't start to wear or anything like that, even after they've been using daily for a few hours per day.

    The Bluetooth connection works well for me in APT-X mode, I am very content with the sound, and while it is possible to tell the bluetooth apart from using FiiO X7mkii + AM03A for driving them, I don't think that the difference is large enough to justify using the cables, especially if using them portably, while out and about.

    There's some call abilities for Bluetooth, but we didn't explore any of those in depth. When we made a call, the person on the other end could hear us nicely, and we could hear them, but that's about it. Voice came out clear and tonality in voice was clear, but there was some parasitic noise on their end, with a bit of delay from the BT connection.


    The bluetooth control buttons seem to work just fine with any DAP we paired them with, including with our smartphones like Xiaomi Mi Max 2, and the bluetooth experience has a very nice overall feeling, with very rare to no dropouts.

    You can change the volume via clicky buttons while they're connected in Bluetooth mode, and those are some of the headphones we tested that go very loud, and loud enough, when connected via Bluetooth. We consider this to be an important aspect, as we like to listen loud, and most BT headphones are usually way too quiet for our enjoyment, MZero surprising us in this sense.

    In the long run, they are a 130$ product which feels nicer than its price warrants it, the looks are elegant and practical, and for the most part the build quality is very good, better than their price tag says they'd be.



    Sound Quality

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    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.

    They have a fairly dynamic sound, which makes up for the disadvantages presented earlier, making them a bassy, dynamic and rolled off headphone, with a clear enough midrange to be fun. They should be nice for those who like a delicious bass, and a fatigue-free sound, being intricate enough in the bass department that they are a kind of guilty pleasure, especially when you combine the sweet bass with their comfort. Pop, Electronic music, Rap, Hip-Hop, and Bass-centric music will sound sweet, while Rock, Metal, acoustic doesn't have enough treble to sound its best. This being said, I wish they made another headphone with this bass and more treble, along with a clearer midrange.


    Soundstage

    The soundstage is fairly good for me, but not quite that impressive overall (especially after hearing many other flagships), being well extended in width, but they have a limited instrument separation, bass, guitars, synths and most instruments / voices going over each other a bit too easy, with the cymbals being not enough audible, and a tad scattered. While electronic music will sound nice on them, metal music will take a hit due to the limited instrument separation, and so will most acoustic and Jazz music.



    ADSR/PRaT

    The ADSR/PRaT characteristics are fair for the price range, a bit on the slow side. Textures are resolved fair for the price range, but the musical note decay is slow, while the attack lacks impact at times.



    Portable Usage

    Here comes a strong positive, as MZero is ultra portable. They are lightweight, the clamp force and clamp angle is just right, and they don't cause any weird noises while being worn and walking. They are bluetooth enabled, with APT-X technology and they have around 32 hours of stated battery life (we didn't measure this since we used them mostly wired), and they are quite comfortable.

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    The Bluetooth Connection is stable and stays stable without many sudden dropouts, APT-X being a very nice addition to this. The connection stayed stable in a 2-hours walk around Bucharest, and this alone says enough about the quality of the bluetooth receiver.

    Listening volume can get really loud through Bluetooth, which we consider an amazing plus, and the bluetooth buttons seem to work just fine with any device we paired them with.

    They are also easy to carry around the neck, if one has to answer a phone conversation and was using them wired, the cable included is just the right length and is quite flexible, but charging their batteries takes a while, around 6 hours from empty to full.


    All in all, MZero has a very nice portable usage and makes a good phone to take on the road.



    Comparisons

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    MZero vs iBasso IT-01 - Starting with the bottom end, both have excellent extension, but IT-01's bass doesn't bleed in the midrange, while MZero's does get a bit in the midrange. IT01 has better musical note articulation and definition, along with better instrument separation, while MZero is smoother and rolls off a bit early in the treble.

    MZero vs Westone UM1 - The sonic signature is fairly similar between the two, but UM1 is a IEM, while MZero is a Bluetooth headphone with a hand more functions. The comfort is great on both, and the small size of UM1 is an advantage, but MZero is quite portable as well. The treble rolls off a bit early on both, both are laid back and relaxing, and both have a very nice bass. UM1 might have more bass and sub-bass, while MZero has a better midrange and especially vocal clarity.

    MZero vs Westome WX1 - The sonic signature is similar between the two, with WX1 having a somewhat better treble extension, with better instrument articulation. MZero has a longer promised battery life, and while they don't have the MMCX Bluetooth cable that comes with WX1, they have an excellent volume while used in Bluetooth mode, MZero being probably the only headphone we heard so far that can get this loud on a Bluetooth connection.

    MZero vs Sony MDR-XB650BT - Sony has better extension in the treble, and a tad more bass amounts, but MZero has more clarity in the midrange and is more dynamic, and much more comfortable, being an over-the-ear design, while MDR-XB650BT is an on-ear design.




    Value and Conclusion

    MO Electronics MOOH BE00BT is a headphone you surely need to consider if you want an 130$ Bluetooth Headphone that is comfortable, has great bass, and a very smooth and relaxed sound, albeit with a somewhat recessed and rolled-off treble.

    [​IMG]

    [​IMG]

    There are some concerns over the sonic quality of MZero, like the lack of details and the fact that they are a tad boomy or that the bass bleeds in the midrange, but placing things in perspective, they are some of the most comfortable headphones I found at the 130$ price range, and even I have used them quite a lot, my girl as well, they are very enjoyable "fun" headphones that will never offend anyone. While not being the most clear headphones, they are clearly very enjoyable and engaging, providing a fun overall sound and feeling to those in need of a comfortable headphone. Taking them with you at work, or taking them on a walk is not going to be an issue, they isolate fairly well from the outside noise, and they provide a rather good sonic performance for their price range.

    We are sure that a large part of their 130$ price tag was invested in including the bluetooth module, the batteries for that, the rather comfortable earpads, the construction quality. The sonic quality, while not absolutely left behind, had a bit to suffer. In the long run, we'd be happy to pay a little more for better sonic clarity and for a better treble extension, MZero having an excellent shape and comfort potential. For somebody who wasn't spoiled by much more expensive headphones, those can be a crazy-fun experience as they are quite dynamic and combine well with electronic, pop and bass-driven music.

    [​IMG]

    [​IMG]

    If you're looking for an 130$ headphone with a nice bass and a good overall sound, we think that you'll love MOOH BE000BT, and that you can hardly go wrong with a headphone at this price, especially if you are into smooth , dark, and relaxing sounds. You won't get the best resolution out there, but you will get lots of fun and enjoyment from the experience, and they live to be what they promise to be, a good deal at their price point, with APT-X Bluetooth and fun bass. We didn't experience better APT-X Ove-The-Ear 130$ Bluetooth headphones yet, even less, so MOOH-BE00BT are some of the best headphones we tested at their price point, despite all the minuses we mentioned. If you're curious to get them, you can rest assured that MO Electronics was of help to customers before, and that despite their older-looking site, they are quite professional in their work. MOOH BE00BT should remain in our minds as a fun headphone that is worth 130$, and does a good job for its money, coming with a hand of features that might come in handy to you.



    I hope my review is helpful to you!

    M&O MOOH-BE00BT

    unnamed (1).jpg


    Disclaimer: This is a review unit from Tom Wang from M&O Electronics, thank you.

    This review is over the Beryllium Acoustic Bluetooth Headphone from M&O, also known as the M&O MOOH-BE00BT. This is my first review of a headphone with wireless capabilities, so this review will have a wireless/portability section added to it that I don't normally do.
    These headphones have actually quite surprised me, they sound better than their price suggests and their extra fuctionality as a bluetooth headphone makes it even more impressive considering the price of these headphones which is $130. Actually they sound great, much better than I actually expected. First things first, let's go over the accessories, build, portability, and comfort of the headphone. These are similar to the RBH HP-2, but have been told they use a newer version of the beryllium-coated driver and some dampening changes, so technically these actually seem to be the better headphones. I haven't heard the RBH HP-2 so I can't comment on how they sound in direct comparison other than other peoples impressions are that they are very similar with the M&O being a bit smoother and more even.

    *Note: Most of my impressions are based on the bluetooth via iPhone 7, I used wired very little on the headphone.

    Accessories:
    The M&O Berylllium Acoustic headphone comes with a hard shell carrying case to hold and contain the headphone and the cables. The headphone comes with an USB charging cable for the built in battery and a 3.5 to 3.5 cable for wired listening on the M&O headphone. The headphone cable isn't anything special as the focus of this headphone appears to be wireless listening. Upgrade cables are very easy to find as it's a very common type of cable and the connector is flush on the left earcup meaning any 3.5mm to 3.5mm can be used on this headphone.

    Build/Comfort:
    The build of this headphone is pretty good overall, the hinges and adjustment mechanisms are flush and move smoothly with no looseness, when it's adjusted it stays in place. There is some minor creaking with the headphone at times. The plastics used on the earcups do feel a bit on the cheaper side. The headband actually feels quite nice and the padding and padding material is nice. The earcups are soft and plush and seem of pretty good quality, the interior foam could be a bit denser but I have no comfort issues with the pads. The earcups do lay flat, but I do find you can only turn the cups only so much the other direction. The earcups have a metal finish with three little vents on the buttom of the metal plate on the earcups which works as a bass port, covering some or all of these will affect the sound. The wired connection is on the left earcup of the headphone, while the charging port and bluetooth buttons is on the right earcup. The earpads are easy to remove, though putting them back on can be a little bit of a challenge as you have to slowly feed the lip of the earpad into the groove. All in all build quality is on the good side and the headphone is well put together.

    Comfort wise, I find the clamp slight on the strong side, not as strong as say the HD 6xx family and the pads are soft and plush and fairly deep with a nicely padded headband. The pads may be a little shallow as some people I know with ears that stick out a lot had minor gripes about, but the earpads are replaceable, so pad rolling may be in order for people with bigger ears. Overall I found the headphone very comfortable and easily wearable for hours, they don't seem to create any hot spots, there is a little bit of stuffiness but that's the norm for closed-backs with pleather earpads.

    Portability/Wireless:
    This headphone is not active noise-cancelling, any noise cancelling is passive from the headphone from being closed. These are the first wireless headphone I've ever had in my possession, so I can't comment on how the wireless connectivity compares to others in the market. The headphone uses a Qualcomm CSR8645 chipset and supports Bluetooth 4.0 and aptX. Sadly was only able to test out Bluetooth as none of my devices supported aptX as I am an Apple iPhone 7 user. Batter life is rated at 32 hours and my own testing has shown this figure to be accurate, I usually got a week without having to charge the headphone again as I use both wireless and wired. I have used the wireless functionality on this headphone more than wired. The headphone can be used both wired or wireless when it is being charged and the headphone can be used wired without any charge. When the headphone is charging a red indicater light comes on and it charges via a USB to USB Micro port in the right ear-cup. To turn on the wireless on the headphone, you press and hold the Play/Pause button on the right earcup until a blue light comes on and it will beep. To connect to the device you go to bluetooth settings on the device your using and look for MOOH-BE00BT and connect to that and the headphone will make an indication noise it's connect. The other two buttons on the right earcup are for volume control. Isolation of these headphones is about average for a closed-headphone.

    The built in microphone for making calls, I found wasn't very good quality on my iphone, I don't know if it's because of bluetooth and lack of aptX or not. I found the range to be pretty good and I didn't have many problems with drop outs on my iPhone 7 when walking around while listening to the headphone. Portability gets an overall high rating for me. Sound quality on bluetooth is actually excellent, it has a lot of depth and sound very pleasing, I was satisfied with what I heard even with my rather picky ears. Compared to wired, there is a little bit of compression, but nothing bothersome in my ears.

    Sound Quality:

    Now to the section most people will be curious about, how do these headphones sound. To put simply very good with a warm tilt and a low-end emphasis compared to most headphones. The headphone manages to have very impressive bass without it bleeding into the mids and without any muffling to the sound, the sound is always clear and defined and the midrange is present. Overall the sound is well-balanced with a slight U-shape curve.

    Soundstage, Imaging, and Detail:

    The soundstage on the M&O is on the intimate side, largely due to the closed-back nature of the headphone, everything within the stage is well placed and clearly defined. The imaging is where I find is one of the aspects where this headphone shines, the image is very defined and there is a lack of a blur around the image, this renders the vocals and instruments to have a very pleasing depth to them that most headphones seem to struggle with, wasn't expecting such good imaging in this price range. The headphone also has a very black background and this makes the image pop out more and helps the depth of sound more. It's not going to have the same sense of scale as say an open-headphone but I don't find this headphone lacking in this area at all, it sounds natural here and doesn't give much of a closed-back effect soundwise, there is a slight closed-back effect but it's mild, it's better than the Sony MDR-1A and both Meze 99 headphones in terms of imaging. Since this headphone had proper depth to the sound, it took me a little longer than normal to analyze it.

    In terms of detail, this headphone punches above it's weight, it has plenty of detail and it articulates both macro and micro dynamics with ease, it easily holds up to more expensive headphones in this aspect.

    I have not tested the headphone on higher end gear much, I am unsure of how well this headphone scales up. But on portable devices and on wireless it sounds fantastic.

    Speed, Dynamics, and Tonality:

    This headphone is actually fast even compared to many headphones upwards to $300-500 range, I can't really get this headphone muddled or confused, this tells me this headphone is on the fast side with a very good transient response. The decay of this headphone is on the quick side. The entire sound range has excellent dynamics and plenty of body, this is not a thin sounding headphone by any stretch of the imagination, it's very much on the full-bodied side, especially due to that deep reaching and powerful bass response. Tonally, these headphones sound natural and don't sound artificial at all. There isn't really any notable tonal offness/off-pitchness going on as say in the Sony MDR-1A a headphone I also own. The tonality is more akin to what I'm used to in Beyerdynamics and nicer Sennheisers, which means it's very good. The sound on the M&O is also very addicting and has this subtle sweetness to the sound I find quite addicting. This is a very easy headphone for me to like. I'm a very tonally and musicality oriented person audio wise, outside of fatigue that's what I focus on the most at first. This headphone is neither dry or what I consider wet/fluid, it sits in-between.

    Bass:

    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.

    Midrange:

    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.

    Treble:

    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.

    Summary:

    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.
