Brilliant piece of kit, I've upgraded twice so this is my third one, customer service is excellent and the ability to record anything playing on your phone and play back makes it perfect!

### ⭐ Title: Clever idea, poorly executed — hopefully soon returned (and you should think twice)
*by C***S on 23 September 2025*

Bought these because the concept is brilliant. In practice they’re a design that rewards only very specific ear anatomy — mine isn’t it. The pads sit on the cartilage, not the cheekbone, so at normal volumes they buzz against the skin and the sound is terrible. I tried every adjustment, headband and swim-cap trick, and they still won’t sit where they’re supposed to, not that I want to walk around with that look all the time. If you want bone-conduction that actually conducts through bone instead of vibrating your ear, look elsewhere. I’ve initiated a return and asked for a refund under my consumer rights — this product, as worn, is not fit for purpose. Consider this a friendly public service announcement: great idea, shame about the execution.
