MW07 GO Review – The GT

Pros –

Very stable yet compact design, Outstanding bass, Smooth and controlled sound, Stable connectivity, Tactile controls

Cons –

No app integration, Isolation bested by competitors

Verdict –

The MW07 Go suits those wanting a streamlined audio-focussed TWS earphone with excellent battery life and a sound that’s warm enough for the GO but balanced enough to be enjoyed at home too.

Introduction –

Master & Dynamic surged onto the scene a few years ago, a New York-based company with big aspirations. Their brand made a name for themselves with their flawless industrial designs that felt built to last. Recently, the company has been focussing on their portable products, launching a competitive ANC headphone alongside expanding their TWS MW07 line-up. The GO is the most economical M&D TWS earphone and has been designed to be their most accessible in every regard. With many reviews pairing up the Plus and GO reviews, I thought it apt to offer this earphone its own dedicated article as there are some key differences between the two models besides the price gap. The MW07 GO carries a $199 USD price tag, you can treat yourself to one here and find the full feature rundown on Master & Dynamic’s website.


Disclaimer –

I would like to thank Master & Dynamic very much for their quick communication and for providing me with the MW07 GO for the purpose of review. All words are my own and there is no monetary incentive for a positive review. Despite receiving the earphones free of cost, I will attempt to be as objective as possible in my evaluation.


Accessories –

The MW07 GO is well-packaged, identical to their more premium earphones. Inside the box are compartments containing the accessories. In addition to the earphones within a new fabric charging case. M&D also include a USB-C to USB-C charging cable and a Type-C to USB-A adapter to allow charging from computers and older plug-ins. Furthermore, 5 silicone ear tips are provided to ensure a snug fit in addition to 3 sizes of silicone wing jackets to suit a wide range of ear geometries. The GO, much like the Plus, is a well outfit earphone.


Design –

Where the Plus is a like for like revision of the original MW07, the GO instead opts for a slightly more compact design representing a 15% reduction in overall volume achieved by shaving 1.5mm off the length and 1mm off the height. Alongside a more rounded design, this specification represents a significantly more tangible result than the pure specification would suggest. The earphone feels substantially smaller in the ear and is 15% lighter to match.


The acetate faceplates have also been substituted with basic hues of TR90 that have been slightly more scratch-prone in my testing and don’t look quite as premium, but contribute towards a very clean aesthetic. Otherwise, the GO utilises a similar silicone jacket and the fit is very reminiscent to the other MW07 earphones. There are no IR sensors and only the right earpiece houses a microphone so the earphones can’t be used independently for calls. On the contrary, the GO has the highest ingress protection rating at IPX6, making them waterproof if one point shy of submergible.


Fit & Isolation –

All of M&D’s efforts have paid off with regards to fit, this is a familiar feeling earphone but easily the most comfortable MW07 by a good margin. Similar to the Plus, the ear fins are of the slightly more acute kind, however, they don’t dig into the ear due to the altered geometry of the earphones. I had to size up the fins in lieu of the smaller housing dimensions and experienced perfect comfort and fit stability once tip and fins sizes were properly adjusted. The fit is medium depth, producing a solid seal and no driver flex. The earphones feel locked in through a combination of silicone fins and angled, protruding nozzles that provide opposing forces of stabilisation.


Combined with their higher ingress rating and lower weight, these are a terrific choice for workouts. Isolation also seems a touch improved as opposed to the MW07 though they still don’t touch sealed competitors nor the noise-cancelling MW07 Plus which will all be better choices for frequent travellers. What we’re left with is above average passive isolation that is sufficient for general commute, especially when paired with their fuller bass tuning. Wind noise is also non-issue as the vents are concealed.


Compact Case –


Alongside a new form factor, M&D has introduced a new case too. It has a technical knit exterior similar to that of the Sennheiser MTW and is substantially smaller and lighter than the stainless-steel unit included with the other MW07 earphones. As a result, it’s a lot more pocketable and unobtrusive to carry. It features a rubberized hinge that lacks the satisfying double magnet lock of the stainless-steel case and the case only offers just over a single additional charge as opposed to 3 on the Plus, for a total 22 hours of listening. Besides these main differences, the case is functionally identical to the steel version, magnetically retaining the earphones and lid, offering battery level via 3 front-facing LEDs and charging over USB-C.  Despite lacking a metal construction, no wireless charging is offered. With a smaller battery, the case is able to charge 40% in 15 minutes.


Connectivity and Battery life –

All manner of connectivity is basically identical to the Plus so I’ll be borrowing snippets from that review. The pairing process is identical and just as straightforward. Upon first removal from the case, the earpieces enter pairing mode and auto-connect on subsequent power cycles. To add additional devise, the earpieces have to be removed from the ear and the power button held for several seconds after which the status LED flashes to denote pairing. One notable addition to the spec sheet includes BT 5.0 which represents more than just an increase in power efficiency. The new earbuds immediately have more stable connectivity and I didn’t experience dropout from my Pixel 4 even in Sydney’s crowded CBD. Latency wasn’t an issue in my uses with minimal issues with lip sync when watching videos. Apt-X is supported which offers greater fidelity, however, Apple users will be disappointed by the absence of AAC.


What is different is the lack of ability to pair each earpiece independently. Additionally, only the right earpiece features a microphone. That said, the microphones is the same beamforming unit as the Plus and produces similarly strong call quality. It was able to isolate my voice well from background noise and recipients reported good volume and immediacy. As aforementioned, neither earpiece has an IR sensor so the earphones are unable to auto-pause music when removed from the ear. As with the Plus, the GO features some of the best battery life on the market, rated at 10hours. I reliably was able to achieve 9hrs of use at low-medium volumes, slightly better than the Plus as there is no noise-cancelling. Quick charge is also supported, offering 5hrs of runtime from a 15min charge. There is no app/eQ support for this earphone meaning that users will be subject to the eQ built into their music app of choice and will have to change the eQ on each source device.


Sound –

M&D MW07 Go

Testing Methodology: Arta via IEC 711 coupler to Startech external sound card. Note that 7-9KHz peaks are artefacts of my measurement setup. Measurements besides channel balance are volume matched at 1K. Take this graph with a grain of salt.


Tonality –

Similar to the above sections, the GO also shares many traits with the Plus with which it shares its driver and circuitry. I can only speculate that the GO sounds and measures differently as a result of a higher impedance filter in order to bolster its ingress rating. That means the GO also sounds better than its predecessor and to my ear is a bit easier to listen to than the Plus despite being less objectively balanced. It remains a U-shaped sound with present and nicely linear bass, laid-back yet clear vocals and a smooth, dense upper midrange. The highs are well-extended for a TWS earphone but lack some of the Plus’ air, being smoother and darker overall. The GO represents a sound technical performance alongside a warmer and smoother sound than the Plus which better suits high-volume listening and will appeal to those sensitive to brightness while upholding a reasonable level of balance overall. This is a wise tuning for its intended purposes, especially as it lacks ANC to combat ambient noise.


Bass –

Similar to the Plus, the GO’s bass has excellent extension with modest sub-bass emphasis. I do notice slightly greater pressure than that model, providing a more substantial kick at the very bottom, however, this is neither an overwhelming nor muddy the low-end. The mid-bass upholds Good linearity with the sub-bass, contributing to a slight warmth and satisfying fullness. As the upper-bass and lower-midrange see progressive attenuation, the low-end remains quite clean in tone, avoiding excessive warmth and tubbiness.

I walked away very impressed by the driver control showcased by the Plus and the GO maintains similar qualities, relinquishing just a touch of mid-bass definition and texture to its fuller sub-bass. However, make no mistake, this remains a well-controlled low-end devoid of bloat and muddiness with the addition of natural to slightly fast decay and great dynamics. The additional fullness is well-metered and surely welcome for an earphone intended for noisy environments without ANC. It’s also commendable that the price cut isn’t to the detriment of technical ability as well.


Mids –

The clear, natural and slightly laid-back midrange of the Plus also makes a return, here with greater smoothness and a slight reduction in vocal size. The tuning is very similar with a rise to a 3KHz hump with subsequent fall-off before picking up in the treble region. However, the GO has a more attenuated top-end with noticeably less 3KHz presence and a smoother treble on top. As such, this earphone is noticeably fuller. Female vocals, in particular, are also slightly more laid-back but command strong clarity with their slight upper-midrange bias, remaining very discernible and well-defined.

The GO carries the warmer tone of the Plus with a touch of additional vocal body and it is perceptibly smoother, to my ear lacking the brightness that could make the Plus a bit intense to listen to. As such, the GO isn’t necessarily more accurate or transparent, but it is better suited for high-volume or longer listening. It doesn’t have a perfect timbre but is naturally voiced with powerful body and strong clarity and vocal definition. It upholds reasonably cleanliness by avoiding excessive bass colouration while the smoother top-end keeps articulation and sibilance in check. This is a more coherent performer than the Plus at the cost of balance between bass and vocals and a touch of separation.


Highs –

I actually prefer the top-end of the MW07 GO over the Plus. In terms of tuning, the peaks and troughs lie in the same regions emphasis picking up around 6KHz and reaching greatest prominence slightly higher up. However, as all have been lightly toned down, the GO has greater linearity. In turn, it lacks the same airiness and open soundscape but is cleaner, more composed and natural. Instruments sacrifice some attack for more appropriate body and texture while retaining adequate crispness. The lower-treble is still slightly crisp and enhanced, however, its presence now sits a touch behind the rest of the mix. Resultantly, the presentation has more contrast and focus as treble instrumentation no longer competes for presence with the bass and upper-midrange.

As aforementioned, middle-treble is also darker yielding a noticeably darker and cleaner background. They roll-off somewhat through the middle-treble and slightly sooner than the Plus, in fact. As such, the GO lacks the same sparkle and shimmer but as its darker middle-treble creates a greater sense of distance, it possesses similar soundstage expansion. Surely the Plus has sharper transients while the GO has smoother and more natural notes suiting its intended purposes; that being, long and high-volume listening. It’s encouraging that in so doing, fidelity has been retained.


Soundstage –

With Good treble extension within its class and a clean, dark background, the GO crafts a soundstage that expands laterally just beyond the head and projects a pleasing sense of depth for a well-rounded image. Imaging performance is sound, lacking the sharp directional cues of the Plus but achieving a more coherent presentation with less emphasized panning and more precise directionality. Separation is slightly reduced compared to the MW07 Plus but it higher within the treble due to greater cleanliness in the middle-treble.


Comparisons –


Master & Dynamic MW07 Plus ($299): The MW07 Plus has a more balanced sound but is overall similar in voicing. It has a more linear low-end with less sub-bass slam but a more defined mid-bass and better control and separation. The midrange is also similarly voiced, but a touch brighter and more intense in the upper-midrange. However, this also brings vocals more in-line with the bass in terms of presence. The MW07 Plus has a slightly cleaner midrange too, both are warm but the MW07 is less full-bodied so both separation and definition are higher. The GO is smoother and more natural in terms of tone, lacking that sense of brightness and intensity.

The MW07 Plus also has a brighter top-end both with regards to the lower and especially middle-treble. It is crisper with thinner instrumentation but noticeably more air and background detail retrieval. The MW07 Plus has slightly higher resolution and better extension, however, it isn’t as clean sounding. The GO is smoother with more accurate instrument body and texture, with a cleaner and darker background at the cost of being slightly less resolving. Both have very similar soundstage expansion, the MW07 Plus has sharper directional cues while the GO is more coherent.

Adv M5 TWS ($200): The M5 TWS is a more mid-forward earphone with a more technical sound. Bass is substantially less present on the M5 TWS and doesn’t extend quite as well but retains good kick and punch. The M5 TWS has a neutral mid-bass and upper-bass, being cleaner and more separated as a result. It has higher control and quicker decay making it more defined detailed at the cost of body and warmth. The midrange presentation is more natural on the MW07 GO, being fuller and smoother while the M5 TWS is a lot more forward, thinner in body but more revealing and neutrally toned. The M5 has a more present upper-midrange and less bass warmth sounding more intense, a step above the Plus in fact.

Due to its well-restrained treble and 4KHz region that redeems some smoothness and density, the M5 doesn’t absolutely fatigue. The M5 TWS is brighter all around up top with a crisper lower-treble and more linear extension into the upper-treble. It has more resolution and detail retrieval throughout but also a brighter background which makes it sound less composed than the smoother MW07 GO. The M5 TWS has more extension at the very top and perceptibly more sparkle and shimmer. The M5 TWS has a wider soundstage while the MW07 GO has better layering with a darker background.

Sennheiser Momentum TWS ($250): The Warmer GO achieves greater parity with the similarly warm and smooth Momentum TWS. The Senn is more V-shaped and even warmer and smoother. It has a touch less sub-bass extension but similarly strong quantity generating a hearty rumble and slam. The Momentum has more bias to the mid-bass, creating its warmer and fuller sound where the MW07 GO is slightly warm but certainly cleaner than the Senn. The MW07 GO has better low-end control and greater definition and detail retrieval as a result. The Senn is smoother and more organic but misses some fine details.

The MW07 GO has more vocal presence which makes it more balanced overall. It sounds more natural and transparent where the Momentum TWS is more laid-back and noticeably smoother within the upper-midrange, granting it a full, organic sound. Neither have an ounce of rasp or thinness, the MW07 GO has more clarity and cleanliness while the Momentum may be too thick for some. In the treble, the MW07 GO offers more full-bodied treble notes, though it also doesn’t possess the same level of foreground focus and crispness. The MW07 GO has better treble extension and both are clean in the background. Both have a well-layered presentation but the GO provides better soundstage expansion.


Verdict –


The GO has been positioned as the most accessible MW07 earphone with the most accessible price to match. Though it makes some compromise to feature-set, the core fundamentals are not only untouched but refined for its intended consumer base. It brings the strongest ingress protection and a lightened, more compact design producing excellent wearing comfort. The same excellent battery life remains and that case is more pocketable than ever. The sound is perhaps most impressive, smoother, fuller and more impactful than any other MW07 earphone. It very well suits high-volume applications such as workouts but without a hint of muddiness or veil. This is a very well-metered warm, smooth sound with an uptick of treble crispness and midrange clarity but never in excess. The MW07 Go suits those wanting a streamlined audio-focussed TWS earphone with excellent battery life and a sound that’s warm enough for the GO but balanced enough to be enjoyed at home too.
