Bought to replace the headset - not good - came with my smartphone Wiko Peax 1. Since it is very difficult to find a headset to the OMTP standard I opted for JVC allows to use both CTIA standards ( the most common) and OMTP through a small order on the wire. This kit has a flat cord, so more nodes. It's really nice. Beautiful build quality and sound quality (it also depends on the source). The headphones would be worth a little less bulky and more rounded than square.
