While most people probably won't notice any huge difference, it's worth noting the MW07 uses Bluetooth 4.2 rather than Bluetooth 5.0 that's on a lot of newer models -- like Jabra's Elite 65t and others. While the latest version of the standard does offer improvements in range and energy use, Bluetooth 4.2 is quite capable of steady connectivity and great sound quality.
Speaking of sound quality, I'm not going to mince words here: The MW07 are the best-sounding true wireless earbuds I've tested. Sure, others might be offer a compelling package at nearly half the price, but strictly in terms of audio, these are at the top of my chart. The company has consistently offered crisp clarity across its headphones, and the MW07 is no exception. M&D typically opts for a more balance tuning -- what it describes as a "natural" sound -- but at times, a subtle approach to bass impacts audio quality. I'm happy to report that's not the case with the MW07 which have a noticeably more punchy low-end for a fuller, more robust sound.
You get a sense of the clarity and detail in the sound with genres like bluegrass and jazz. Styles with delicate instrumentation really show what the MW07 can do. I could tell a big difference when streaming Punch Brothers' All Ashore or The Earls of Leicester's Rattle & Roar. There's better detail than a lot of over-ear headphones I've used. The booming low end makes songs like TesseracT's "King" and Pusha T's "If You Know You Know" soar. It's not over powering, but the level of bass here creates a full soundscape that lets metal, rock and hip hop shine. True wireless earbuds can sometimes show a little too much restraint here, which makes some genres suffer. The MW07 is not on that list.
There's also noticeably more volume here than many of the other true wireless devices I've tested. Unlike a lot of these earbuds, and a few sets of Master & Dynamic headphones, the MW07 is plenty loud. I rarely found myself needing the maximum level to find the oomph I was looking for.
Comfort is always a top consideration when it comes to buying new headphones. However, when you're talking about something you're going to be cramming inside your ear canal, there's only so much comfort you can expect. Finding the correct size silicone tips helps, and foam is often a better alternative. For me, any true wireless product I wear for hours at a time will eventually start to drive me nuts. It's just part of life. This isn't a knock against the MW07 per se, none of the options I've test are really that comfortable after hours of use. At least this pair doesn't stick too far out of your ear (like the Bose SoundSport Free) so you can add not looking silly as a plus in the emotional comfort department at least.
With a $299 price tag, Master & Dynamic is comfortably situated in the premium tier. If you don't mind shelling out a few hundred dollars, Bang & Olufsen's Beoplay E8 is another option at the same price. Sennheiser and Audio-Technica announced true wireless earbuds for $300 and $249, respectively, back at IFA. Those aren't out yet, so I can't offer any impressions, but they are two more high-end selections to consider in the months to come.
