They look good, they sit behind the ear comfortably. Length of the earhook, I would say optimal, as when planting them especially and not visible, while it is convenient to press the button to pause/answer the call. Through the wall works without problems. The microphone is bad, they do not hear me in a noisy place. I would like better noise reduction when talking. So, forget about him. When connecting/off/losing Bluetooth signal/calls-there are their voice alerts, which is convenient. Keep the charge for a long time. From morning to evening I listen to music and by evening to stay 80%. So you can not carry the case with you.

Nice!!

While it’s a good product that converts your favourite IEM to True Wireless but it’s only AAC. Considering the price could have had LHDC if not LDAC or AptX HD.

It has enough power to power your IEM with multiple Drivers.

The charging case is very big but has big battery although the lid snaps shut using magnets but its lid is a bit flimsy, you need to be careful.

it’s very comfortable to wear due to hook design. Easy to use in gym or exercising as it does not fall out like other TWS.
