The sound quality is amazing, definitely enhances the concert experience! The app could have better instruction on volumes control. And it would be great if the device had options on earbud sizes, especially for small ears.

We got these as a bonus for attending a show for Eltons 2 millionth fan. The concert really sounded a lot better with the PEEX system it’s pretty subtle still seems “live” but you can adjust and hear vocals somewhat louder etc. it really works well in real time and the concert sounded a lot more muddled without the headphones. I turned the keyboards up hoping to hear more piano and it actually turned up all the keyboards so one can’t adjust very specific instruments yet.

Tried them out for the Elton John concert in the Tacoma Dome. That venue has terrible acoustics at the 200 level and above. It definitely improved the sound. I intentionally turned up Elton John’s piano and vocals and it sounded better than without the device. My only disappointment was the sound quality of the earbuds and fit. I would have brought my own but I only have Bluetooth. I really, really, REALLY wanted to give this a 5 but the sound quality could have been better. Make this Bluetooth and you have a winner!

I used this at an Elton show in Atlanta; it sounded great on my custom in-ear monitor earphones and was a breeze to use. Looking forward to using it again soon!
