Master & Dynamic MH30 Review – Introduction

If you ask the question, what are the best-looking headphones out right now, then you’re going to have a hard time ignoring Master & Dynamic.  A relatively new company in the portable audio space, the companies designs are so striking that they have become trendy extremely quickly.  The MH30 is the slightly smaller and more portable offering that sits just below the full-size MH40 headphones in M&D’s lineup and promises to deliver top-notch sound quality in a premium package for people on the go.  The feature set is pretty incredible on the ’30s, certainly on paper and streaks ahead of what you could find on the market as little as 5 years ago—40 mm dynamic drivers, high-grade materials, detachable cables, and a super-compact profile when folded away. There seems to be a lot to like here, and the MH30 is also available in a range of color options to suit your own personal style and is available globally.  We have the space grey and black colorway, so let’s get down to the full review.

Packaging – Whats in the Box?

Right from the jump, the MH30 headphones impress, which starts with how they are presented to you. You know you are going to be getting a premium device the minute you pick up the packaging.  A large and striking box sleeve with tasteful graphics, eye-catching fonts, and all the information you could want about what you will find inside is a good start, but it just keeps getting better from there.  You pull that small ribbon tab on the right and slide out a heavy all-black cardboard presentation box.  It’s hard to describe unless you see and feel it in person, but the packaging materials and attention to detail are just some of the reasons why Master & Dynamic have made such an impact in the headphone world. There is no compromise with materials right through the design, and that even transcends into the packaging quality, no flimsy paper and plastic here.  The best way to describe it is a word that I’m sure I will use throughout the rest of this review, premium.  

Flip open the box, and you are presented with the headphones, which are outlaid to show the beautiful ear cup design, as well as a small puck-shaped leather case.  There are generous amounts of dense foam padding throughout, and you would have to imagine the postman will have to straight-up drive over the box to damage the precious cargo inside. 

At the end of the day, this is just a way to get a set of headphones to you, but something has to be said for getting nice packaging.  It makes the whole experience of getting new gear a bit more exciting and special, so hats off to M&D for not skimping on the style points even with its cheapest headphone offering.

On-ear headphones usually have very little in the way of accessories, but Master & Dynamic have excelled in their choice of additions to the overall package.  First up, right slap in the middle of the box, there is a beautiful round leather case inside of which lies MH30 cables.  Its beautiful quality case looks great and is actually functional.  You will find 2 sets of cables and a 3/4 inch jack adapter in that box and both cables are of excellent quality and very resistant to tangling.  One cable is the straight through 3.5mm to 3.5mm (male to male) jack adapter that goes straight from your DAP (Digital Audio Player) and into either the left or right ear-cup.  The other cable has an in-line remote functionality for use with tablets and smartphones making it the preferred option for those who use the MH30 headphones on the go. Jack points on both cables are incredibly well made with knurled aluminum for increased grip and durability and adequate strain relief.  

Finally, under the top level of the box, you will find an unnecessarily thick user manual (I think in 2016, we have all worked out how to use headphones) and a soft style headphone carry bag.  I know I have said it many times here before that I will always prefer a hard case storage solution, but looking past this, the included bag you get with the MH30 is, of course, of the highest quality. Thick, hard-wearing denim on the outside, soft-touch cotton on the inside with a separate pouch for your cables are complimented with a magnetic clasp mechanism and leather pull tabs to set it apart from the cheap and nasty thin velvet pouches commonly offered on similarly priced headphones. 

As mentioned, due to the inherent design of headphones as a product, there is not usually a lot of companies can include, but Master & Dynamic have done well in their choice of extras and especially when it comes down to their material choices for them.

Design & Build Quality – Its basically a tank

In a world where flagship headphones come and go.  Where designs change almost every year, where audiophiles think new and shiny is always better, I still feel that the Master & Dynamic MH30 has a very timeless quality.  One will have a hard job not to compare the M & M&D headphones in some ways to that of Grado.  That’s about as big a compliment you can pay to any headphone company when it comes to aesthetics.  The MH30 has a modern retro styling combined with high levels of finish and an impeccable choice of materials to make them every bit as good to look at as they are to listen to.  

Plush leathers and solid metals are what the MH30 is all about, and you won’t find anything in the way of nasty cheap plastic.  The ear cups themselves are rock solid, all-aluminum affairs making them incredibly hard-wearing. Traditional strain points such as the sizing sliders and hinges are made from steel to add further strength.  Up close, you immediately understand how well these materials work together because, in hand, they feel like a tank.  

During the course of the review (and almost every time I pick the headphones up), I still find myself impressed by the level of fit and finish, and its really a struggle to find fault in this regard, especially compared to some of the competition’s offerings at this price point.

Size adjustments are carried out using a sliding arm system that feels plush and smooth yet still manages to hold its place securely whilst being out and about.  The MH30 are a collapsable design and feature solid metal hinges located just below the headband’s bottom when folded up. The MH30 presents a tiny footprint, making it ideal for throwing in a backpack or even into some larger-sized coat pockets.

So the headband on the 30 is made up of some very plush feeling cowhide leather. This sits over the top of a metal wire that we found easy enough to bend for added comfort if you had an unusual head shape.  There’s just enough padding, but if I was nitpicking (extremely nitpicking to find anything at all to say bad about the design), there could be a couple of extra mm of insulation up there. 

The ear-pads are plush and supple and have one of the coolest methods of detachment on any headphone. Replacing your pads usually can be a real fiddle.  Trying to pry (and not rip) replacements over the top of the lip of your cup is no fun task, but Master and dynamic uses a magnet system to lock them flush while 3 pins keep the pads from rotating on the headphones ear-cup. As a result, changing the pads on the MH30 takes a couple of seconds.  A simple and well-done design feature that we wish was on every headphone.


Comfort & Isolation – All-day listening

We found these Master & Dynamic headphones to be of an average comfort level.  Of course, this is inherently due to the design being of the on-ear variety instead of the more airy circum-aural (Over-Ear) style.  We were fine for the most part, but after a few hours, you might want to take a break and let your ears breathe a little.  The clamping force is perfect, strong enough to keep the headphones fitted securely but not too much to cause discomfort.  

The earpads are absolutely exceptional.  Beautiful soft lambskin leather is used as the point of contact with your skin instead of the tougher cowhide leather used on the headband. Lots of sub $1000 headphones will still use artificial synthetic (protein) leathers on their earcups.  Usually, I don’t have a problem with that as synthetic can be perfectly soft, but with the lambskin pads, I find my ears tend to sweat a whole lot less in hotter climates.

Isolation is good, not at the level of the legendary Focal Utopia. Still, they can sufficiently drown out most noises an average commuter will face and also work well drowning out ambient noise whilst flying.  You might think from looking at the circular pattern outside that the MH30 are open-backed headphones, but it’s just an illusion.  These are closed-back and do isolate well.

Call quality was tested using an iPhone 6S and 5SE in combination with the included inline mic cable. Again I was highly impressed and one of the best in-line solutions we have tested to date. Clarity was extremely high, and there was no noticeable distortion or hiss from signal interference. The microphone hangs just below the chin giving ample clearance from bashing one’s cheek or chest that can result in loud booms down the line to your callers. Finally, the remote section has a nice tactile feel and click to them and is perfectly fine for blind operation.

Sound Quality – Rich Notes

Having heard the Master & Dynamic MH40 some time back, I expected a similar, relatively neutral, and balanced sound in the MH30.  However, while there are some similar flavors to how the MH30 and MH40 have been tuned, it’s best to look at these separately rather than as a dumbed-down version of the MH40.  

The signature of the MH30 lies slightly on the warm side of neutral, something I like a lot and something that benefits a lot of the modern musical genres. The headphones manage to pair very well in particular with the rock, acoustic, and indie genres and hold up great when listening to pop and even more bass-centric genres like house and hip-hop.

There is a definite air to the sound with solid levels of both depth and width, allowing you to feel like you are sitting a few rows back from the artist. Many on-ear headphones do sound somewhat boxed in, so it’s nice to have a little more of that open space feeling in such a small package.  Imaging wise allows you to place instruments quite well, especially when used in combination with binaural style recording, but any well-mastered track will also show a solid imaging performance.  Note decay is perfect, probably due to solid materials, which is further evident in the noticeable lack of resonance created from the earcups.

Source wise I had no problem driving the MH30 through any of my mobile devices, whether it was the Shanling M2, Questyle QPR1, Lotoo PAW 5000, but the standout pairing was the Opus #1.  In practice, though, the MH30 works well, and there is little need for excessive amplification with them. Yes, you will get more from them if you use them with a high-resolution DAP, but as most users will be using them on the go and not wanting to carry too many devices with them at one time.  I suspect most modern smartphones will provide adequate power to drive the MH30 well.

Bass extension is admirable, and the 40mm drivers and provide you with good amounts of depth with minimal overlap and bleed into the midrange.  True sub-bass extension was not overly powerful, but they can get down reasonably low and are only really pushed past their limits when used with extremes like deep dubstep and darkwave tracks.  The bass on most genres was observed to be detailed and snappy with a decent amount of speed, allowing them to keep up with some of our more chaotic test tracks.  

The midrange is absolutely the highlight of the MH30.  It is a presentation that will entice you deeper and deeper into your listening session.  The hints of warmth combined with a high level of detail for a portable headphone really impressed us.  In fact, I was so impressed that I could see the Master & Dynamic MH30 becoming something I would listen to on a day-to-day basis.  

Vocals come across as smooth and tight, and both male and female vocals were given ample space to shine.  I found myself listening to Everlast’s White Trash Beautiful and loved the weighty combination of those gravel vocals and acoustic guitars but then I could flip on some Rhiannon Giddons (Carolina Chocolate Drops) and get swept up in the emotion of tracks like Leaving Eden and Last Kind Words.  Acoustic guitars, it seems, are what the MH30 was made for.  I kept listening to Rodrigo y Gabriela, and yes, the headphones have warmth, but the 40mm drivers also have the speed to keep up with extremely fast-paced and complicated compositions.  

Highs are, for the most part, pretty inoffensive and laid back, but they also don’t shine as brightly as the other frequencies.  The good thing here is that there is nothing that even slightly resembles sibilance either from the treble or from the upper midrange, and this manages to make for easy long sessions without much in the way of fatigue.  Ultimately I think this is a good choice for portable headphones as they are more commonly used as “all-day” devices, but if you are a fan of upper-frequency sparkle, you might want to look elsewhere.

Conclusion – The final word

I knew coming into this review that if Master & Dynamic were able to implement their obsessive attention to detail that was shown in the creation of the MH50 headphones and get it into a portable package then they would be onto a winner and in the end, the have more than met my expectations.  

The MH30 have an abundance of things going for them, more than enough to give them a spot on Audiophile On’s list of best headphones 2016: they have stylish looks that are eye-catching enough to be classified as a fashion headphone; They are constructed from high-end premium materials such as lambskin, cowhide, steel and aluminum which is combined with the incredible build quality and exceptional fit and finish.   Accessories are well thought out and expertly implemented and, save for the lack of a hardshell case, are above the bar compared to similarly priced competitors.  Then there is the sound which is tuned so that it will suit the majority of listeners due to its ability to work well with so many varied genres and cause relatively low levels of fatigue over long listening sessions.

Priced at just slightly over $300, they also represent good value for money as a total package when put up against the competition from KEF, Bower & Wilkins, and Sennheiser.
