Open Ear Headphones Bluetooth V5.3, Clip on Earphones Wireless with Earhooks On-Ear, Sports Headset Bluetooth with 4 Microphones, Noising Cancelling/Long Battery Life/with Charging Case

They're not bad. Certainly they're very comfortable and surprisingly secure. Sound quality is OK. Not very bass-heavy (which surprised me considering the size of the drivers) though fiddling with the fit can make quite a difference. The fit, feel and sound quality actually kinda reminded me a bit of the classic Sony Walkman headphones of the early 1980s. They don't feel particularly robust, but they have held up OK so far and at least they're consequently rather light meaning they can be worn comfortably for hours. Battery life seems to be very good - at least 8 hours at reasonable volume. The charging case works well. It's large but quite flat so is quite pocket-friendly. Would be better if the case had a remaining charge indicator inside. I think they're a bit expensive compared to some of the new open-ear designs available, but on the whole I'm happy with them.

The clips do not ‘click’ after a few uses. The plastic clips work on a pivot within the earpiece, which when new are reasonably firm and positively ‘click’ open and lock. The pivot has now worn out after less than 4 months of light use and no longer remains secure when on my ears, so the ear pieces simply fall off your ears if you move your head to one side or look down etc. There is no way to adjust them and I cannot find a process for returning them under warranty. Very disappointed!
