Master & Dynamic MW07 Go

Sweet-sounding, sporty True Wireless in-ears with an unusual design

The MW07 Go are comfortable and extremely snug fitting in-ears from Master & Dynamic. They are particularly suitable for sports activities due to their sweat and water-resistant finish conforming to IPX6. A powerful, multi-faceted sound is provided by 10mm beryllium drivers, and aptX support a high-quality audio codec. These low-profile headphones also have a long battery life and a stand-alone remote for device control.


Special mention should be made of how comfortable these headphones are; they do not cause any pressure issues, even during prolonged use. The New York-based audio manufacturer provides them with an extremely secure fit in the auricle by way of the silicone wings, which are supplied in three sizes, and which can easily withstand even strong vibrations during sports. Since these in-ears are supplied with ear tips in five different sizes to complement the wings, there is a high degree of adaptability. Another practical feature is that the Bluetooth earpieces, with their flat design, can be worn under a hat if you wish. The housings are made of a lightweight and durable TR90 composite, much like that which is used to make high-performance spectacles. The handy charging case is made from a particularly lightweight new technical fabric. As a result, the case weighs only 38 grams, while the total weight of the cordless system is 56 grams.

Compared to the MW07 the runtime of these headphones has increased considerably. Despite a higher level, the Go model has a runtime of over ten hours, which is remarkable for True Wireless in-ears and makes them very good value. Additional mobility is provided by the quick-charging function of both headphones and case, which are each 50 per cent charged after 15 minutes and fully charged after 40 minutes. This means that the in-ears can be used for a good five hours, and the battery reserves of the case are sufficient for a quick charge and a full charging cycle, which provides an additional runtime of more than 15 hours – more than acceptable, in view of their low weight. It is noticeable, however, that the display on iOS devices does not provide a reliable indication of battery status, with fully charged headphones not showing at 100 per cent, but (depending on the device) displaying a charge of 94 or 92 per cent; at 46 per cent there is a dip so that, in real terms, the battery life is only 40 minutes. Another unconvincing bit of their design is the magnetic lock on the case, which is too strong for the lightweight material; it doesn’t stay open when the headphones are removed or inserted, and so the lid has to be held in place. On the other hand, the accessories include a high-quality USB-C charging cable as well as a separate USB-C to USB-A adapter to supply power to the case.

Device Control

Pairing your MW07 Go, which support Bluetooth standard 5.0, can be done by removing them from the case and switching on the system which automatically puts them into pairing mode. If a wireless connection exists, the multifunction button on the top side of the right-hand headphone serves to control the Play/Stop function, as well as answering and ending phone calls. Pressing and holding the button activate voice assistants. In addition, it is also possible to select a title by double-clicking to jump forward and pressing three times to jump back. The volume control on the left-hand headphone is also easy to operate using a double button, and the remote has clear pressure points. Single mode is also supported on the right-hand side, with the system automatically recognising whether one or two headphones are in use. However, speech intelligibility on the phone appeared to be limited, as the users’ voices sound quite soft and dull. The wireless connection also proved not to be particularly stable within an urban environment, as there was an increased susceptibility to interference in combination with various Android and iOS devices beyond a range of seven to eight metres. Individual dropouts started to occur even at shorter distances.



The tuning of MW07 Go tends to be neutral, but by no means sounds soberly analytical or sterile. Even though most of the tuning was done without embellishment, the basic character is very pleasing and suggests a degree of smoothness. Even the well-defined basses have a subtle emphasis, play energetically and reproduce down to the low bass range, while vocals are presented in a wonderfully natural and lively way. Only in the trebles is a slight imbalance noticeable, as there is a tendency to exaggerate sibilants, but this does not mean unpleasant harshness. Unusual for Bluetooth headphones, both the resolution and the existing dynamics seem fine, especially since the stage feels very open and spacious for an in-ear system. However, you have to accept a slight background noise, and while Android users benefit from the high-quality aptX codec, only the SBC codec is available for iOS devices, as support for the AAC format has been dropped. Despite the finely tuned qualities of the all-purpose design, these in-ears also make a good impression for use during sports thanks to the powerful bass and high output.

Master & Dynamics MW07 Go scores points with a very stable, comfortable fit and a remarkable battery life, which in combination with the quick charge function of the headphones and charging case, provides a high degree of mobility. Their sound is also a successful blend of a neutral basic alignment with slightly amplified basses, which reproduces all musical styles with great attention to detail and appealing dynamics, while at the same time providing powerful support for sports use. The shortcomings of these True Wireless in-ears, on the other hand, are the rather limited Bluetooth range, the slight background noise, and the lack of support for the AAC format.
