These have gone back but what I can tell you is they were quite bass heavy which chewed into the mids quite a bit. They also sounded quite recessed/veiled to my ears, even though they improved with break in. The fancy stuff that Yamaha was selling these on the premise of was useless in my opinion.
My Yamaha HPH-W300 cans (which I've had for more than a year, and have used almost daily) remain the best sounding bluetooth cans that I've heard to date, with the only exception being the Airpods Max which I recently tested extensively. The only thing that's put me off the latter is their price as well as their battery life, which is poor. The day any company can make cans that can sound as good, at half the price, with double the battery life, and the same build quality, I'm sold. That's saying something given I'm not even into the Apple/ios ecosystem.
Hi Romani, interested to hear more about your experiece with the w300's. would you say the sound is considerably better than the e700s? and how did you find the isolation and comfort in comaprison?
cheers
