Very good prduit despite a few minor flaws

External Quality: the headphones seem solid and well built. The materials are pleasant to touch ,. Only the cable is a little stiff.

Appearance: the headphones are very "big" because probably the embedded electronics. The advantage over headphones with controls on the cable, there is less weight on the cable, therefore more comfortable to wear for me. But visually it is without doubt strange for others to watch.

Sound Quality: no complaints. The sound is clear and precise, a few comparisons with my wired headset (Ultimate Ears) give no real difference in sound quality. In this regard, flawless. FYI: Bluetooth is V3 with SBC codec support, AAC, APTX (only mentioned in available online user guide). I have not managed to find out what codec with my phone stream music on the headphones.

The port is stable, provided you find the right sizes for caps and fasteners, tested on and foot race.

There is one button for all orders, and the volume is initially set at a low level. And it takes a few small trials to master the handling of orders. I have not tested or stored any combination. To increase the volume, you have to click two times quickly: a short press and a long press 2nd.

The order and size headphones are for me the defects (not prohibitive) of this product.

The battery life is a fair bit, it turns around 4:00.

Note: I bought mine at 92 which is quite correct in terms of quality / price ratio.
