The headset came in a bundle with my Yamaha Keyboard. Very light and comfortable (if you have a big head). Long and very sturdy cable. The adaptor from 3,5 to 6,3 mm it’s a welcome bonus.
Now, about the sound... great for keyboard, bright medium and clear high frequencies. The bass it’s there but the headset it’s not for HIFI systems. So, price/quality very high if you understand the purpose of the headset.
For music enthusiasts, you can find on Thomann website headsets from: Sennheiser, AKG, Sony. And you will still find people complaining about the quality of a 300+ Euro headset :)
