Really a very good product, as good as the Sony MW1 Smart Wireless Headset Pro kit, a bit more powerful (over 115 dB), so attention to volume.
The manual is in Japanese, but if one is a little geek, 20 minutes are enough to be used fully.
Small tip, the fitting BT button is located under the cover next to the mini-usb socket ... (stores the last 8 connected devices).
Tested PowerAmp (Android) + headphones Audio-Technica ATH-WS55 and SONY MDR-1A, rendering is really good.
