SUNDARA (open-box)

The sound quality is excellent. Putting them on for the first time feels so weird! Without anything playing it feels like you're not wearing any headphones. They are almost completely transparent to the environment. The drivers are so sensitive to back pressure that having your hand a foot away from your head will change the sound.
This is not a complaint, quite the contrary! This is probably how every open back planar headset behaves, I've just never had a pair until now.
Since they are open back and very transparent you can't use them in noisy environments but when you're at home you will experience full immersion and accurate sound.

I am really delighted with these headphones.and the fabulous service received from Hifiman store. These headphones serve to connect to my FIIOJM21 dac player and have a very vivid sound stage . 5/5 stars
