The Marshall Mid's arrived yesterday afternoon, so had the chance for a direct comparison with the Bragi's.
Again, pairing was straight forward, and initial impression was of comfort and (for me) good sound whilst listening to music from my phone. As well as bluetooth, a cable is suppled if you want to have a hard connection.
The control button on the left side works reasonably well, though is slightly vague in operation (toggles different directions for volume, track, phone etc). Construction quality is very good, and they fitted tightly without being too tight.
The ports for hard wiring and USB connection are on the right ear.
Overall, they're very good, and I'm sure that I'll get a lot of use out of them. However, having started to use them to watch TV last night, I reverted to the Bragi's as for my ears anyway, they win for speech clarity and peripheral noise suppression.
