Got this as a backup and for use while my custom in ear monitors are being made.... I was surprised how responsive they are. Clear highs, beautiful mids and solid lows. Personally think they are worth every penny.
Every headset I've bought has a volume level that stops too low, especially when working out and your blood is pumping which can cause ear ringing. These work so good, goes loud with a great balance of treble and bass, i'm going to buy a few more. Good job with making these!!
