Verdict
Yes , they ’re a little fleck bulky and the sound they produce is , in absolute terms , a niggling bit lop - sided . But the MW09 are deeply satisfying as objects - to the point that you may be prepared to neglect their piffling defect …

Introduction
Master & Dynamic is n’t the first rather self - consciously premium audio brand to have run into the true wireless conundrum : how do you make a mathematical product that is , by necessity , as small and unaccented and unnoticeable as potential seem upmarket and , well , bounty ? Just because it is n’t the first , though , that does n’t make Master & Dynamic ’s job any easier .
The MW09 are surely priced like a premium mathematical product . So how exactly has Master & Dynamic decided to apologise your outlay ? And has it succeeded ?
Availability
The Master & Dynamic MW09 true radiocommunication in - ear headphones are on sales event and in the United Kingdom they ’ll set you back either £ 319 ( with aluminum rouse case ) or £ 369 ( with Kevlar charging case ) . In America the go pace is $ 349 or $ 399 , while in Australia you ’re credibly look at AU$599 or AU$699 if my understanding of international commutation rate is anything to go by .
you’re able to pay more than this for true wireless in - ear earpiece ( Devialet andMontblanc , I ’m looking at you in particular – and do n’t get me started on Louis Vuitton ) , but every bit you’re able to give less and get something extremely well - regarded from the likes of Bose orSony . So there had easily be more to the MW09 than some option materials …
Design
The MW09 earbuds are the Greco-Roman wind to match contour , and they are beautifully constructed from a combination of charge plate , anodised aluminium and sapphire glass . Each earbud is not on the nose small , and at over 8 M each they ’re quite heavy – must be all of those premium material . An IP54 paygrade means you do n’t have to be super - careful with them , though .
Even the more expensive Kevlar option for the charge lawsuit does n’t make it all that much of a flyweight , either – although to be fair , its 50.5 g is definitely preferable to the 62.5 g of the ( somewhat more affordable ) aluminium alternative . Each showcase isIPX4 place , though , so the occasional water - splash should n’t be problematic .
If you visualise the atomic number 13 saddle case option , you could choose between black buds in a contraband case or silver - and - white buds in a silver case . Go for Kevlar and you may peck between blue and disastrous , fleeceable and black , atomic number 79 and atomic number 79 , or gunmetal and mordant .
Rather than allowing the lovely glass finale of the exterior of the earbuds to get calumniate by using them as a capacitive spot surface , Master & Dynamic has or else fitted forcible controls to the sharpness of each earbud . They can be used to align volume , bicycle through the ANC choice you ’ve defined in the command app , skip frontward or backwards , wake your player ’s aboriginal phonation helper , and take on or suspension music . It ’s a fiddly and rather hit - and - miss implementation , though , and nothing like as refined or straightforward as a well - sorted sense of touch - Earth’s surface is .
Features
There ’s really no arguing with the elbow room Master & Dynamic has specified the MW09 . It ’s unfeigned that you ca n’t judge a book of account by its cover , but it ’s possible to get quite excited by the prospect of a pair of true wireless in - pinna headphones when checking out their specification .
The MW09 use Bluetooth 5.4 for wireless connectivity , and compatibility with aptX Lossless and aptX Adaptive codecs means lossless 16 - bit/44.1kHz resolution is uncommitted ( if you have a reservoir player than can deliver it ) , as is a lossy 24 - bt/96kHz . There ’s also a low - latency gaming modality , and the MW09 are alsoAuracast - quick . They ’re determine up for multipoint connectivity , too .
Once it ’s on panel , sound is served to your ears by a span of 11 mm Be full - range of mountains dynamic driver – Master & Dynamic is n’t quote a frequency response , but I ’m expecting very depressed to extremely high as a lower limit . Each earbud also features three mics to take care of telephony , voice ascendancy and active noise - cancellation .
There ’s a fair morsel of adjustability useable where ANC is concerned , too . As well as off , it ’s potential to choose between three Ambient positions ( natural , voice or knowingness , which are basically grade of volume ) and three ANC positions ( max , all 24-hour interval and adaptive ) .
The MW09 can be charged either via the USB - C one-armed bandit on the side of the excite fount , or by using any Qi - certified bill pad of paper . And unless you ’re dead caning the volume , the earbuds will escape for over 15 hours before they require any attending – which is a very decent material body in anyone ’s spoken language . With two further full commission in the instance , you should be able to go two day and two nights without resort to mains index .
The dominance app itself is loose for Io and Android , and is in its own way just as classy and fashionable as the earbuds it assure . As well as deciding on your active noise - cancellation of Ambient Sound options , it has a five - band EQ with both presets and the option to save a custom setting , features an acoustic sealskin run to verify your earbuds fit aright , set aside you to switch in - pinna espial on or off , set an automobile off meter boundary , and check for updates . It ’s stable and useful – which is about all you may reasonably require .
Sound Quality
With the EQ preferences give well alone , with the MW09 relate to a Samsung smartphone via theaptX codec , and with a TIDAL - derived FLAC file of Barry Adamson ’s The Vibes ai n’t Nothin’ but the Vibes playacting , these earbuds take next - to - no time to unveil themselves . They give every feeling of wanting to have the music know who ’s boss around here .
What this means in practice is that the MW09 overstate the lower frequencies while rolling off the top end . Neither trait is fatal in this instance , but it ’s noticeable . The bottom conclusion is big and bluff , and punches with existent determination – but it ’s sanely well keep in line where attack and decay are concern , and so rhythms are expressed with some positiveness and impulse is keep .
Bass sounds are pretty elaborate , too , with good deal of variance in tone and grain to accompany the out - and - out thump . The top of the frequency range of mountains , meanwhile is perfectly fine and expressive until it arrive at authentically high – and then it ’s rolled off quite steeply . It ’s possible to add a little more bit and shine to the top end by using the EQ options , of course – but the knock - on effect of this is a slight ruggedness and edginess that is just as unwished , in its own way , as the sudden roll - off it substitute .
In between , though , the midrange take no excuse made for it . It ’s detailed and illuminating , expressive with singer and has sufficient dynamic magnetic variation to make the harmonic change in a vocalization or an instrument perfectly plain . The MW09 create a very plausible and expansive soundstage , too , so a singer lodge in the midrange has sufficient space to stretch out without worrying about getting swamped by all that low - frequency presence .
flip-flop to aQobuzfile of Rude Girl on Rotation by of Montreal and the dynamic thrust the MW09 are capable of becomes evident . Without shifting quality in the slightest , without sounding in any way fluster or accent , the Master & Dynamic simply put significant distance between the most and least intense section of the recording . And , again , they are adept enough with harmonic variation to paint a complete and colourful sonic picture .
In some ways , the combat-ready racket - cancellation mimicker the audio quality of the MW09 – or , rather , represents the flip - side . Perhaps it ’s to do with the earbuds ’ reticence where the higher frequencies are concerned , but the Master & Dynamic seem to have no problem in dealing with high - frequency misdirection from outside – and without throw any tip of comeback - signal or otherwise betraying how hard they must be make for .
They do a very decorous job on ambient sounds in the midrange , too – but they are less successful where bass - y noises are worry . If you ’re hoping to totally bar that aircraft trailer ( and not just the drone of its passengers ) you may require to cast your net a little bit all-encompassing …

Should you buy it?
This is n’t the first Master & Dynamic product to see and feel a cut above its nominal rival , and I doubt it will be the last .
The MW09 are an enjoyable listen , certainly , but you’re able to get a more complete ( or , at least , a more realistic ) sound from some more low-cost alternatives .
Final Thoughts
There are reason why the Master & Dynamic MW09 are n’t for me : my ear are on the smaller side , I dislike the physical control , and the sound they make is just somewhat skewed . But if they turn out to be just the tag for you , I sha n’t reason – because there is plenty of substance to go along with the expressive style here .
