Impressive
This pair of in ear-phones are class leading across the board, having bought (and returned) similarly priced items from major competitors such as Sennheiser, RHA and Sony.
Stand outs are as follows.
(1) Audio quality. The flat EQ out of the box (no run in required) is very clear, has a good sound stage and appropriate bass response. The Jaybird app allows you to fully customise the EQ and it has a noticeable effect.
(2) battery life of ~14hrs while connected via Bluetooth to a Pixel 3 at 45% volume (which is on the loud side for me)
(3) comfortable and versatile fit. I will not compromise on this. I use this for my commute and while training. Earphones have not fallen out in thr 7+ months I have owned these.
There are other features and I could keep giving praise but I think you get the idea. These exceed the competition at this price range. I haven't tested the form factor at higher prices.
