This is a much better concept and product than I expected

I think it's a great concept and a great device.

They really are an amazing concept that works well

It's an excellent concept, and has a lot of promise

So as much as I loved the concept of open ear, I don't feel it's there yet and can't compete with the perfect-in-almost-every-way delivery that Bose QuietComfort gives, so I'll just accept the sound isolation sealed earphone experience for now.

I finally had to return it.3 stars for the ambitious concept heading in the right direction.

I love the concept and the headphones sound great.

Interesting concept, high quality product

They won't replace your Jabra 65T or Bose Soundsports for the gym, or isolate you from the world at the end of your busy day like your Soundlinks or Sony
