probably the best on the market

why only 3 stars? almost 100 euros but are a bit steep and for that price the nerves misfire but pretty (in a song of 4 minutes increased about 10 times there). the connection is simple, the range of about 10 meters is sufficient. the sound quality is good. have the adapter connected to a Yamaha receiver RS700 coming sound boxes Nubert, the music (sometimes wave, sometimes 320 mp3) I play on my MacBook Pro 2011 OSX 10.7 that supports APTX. the latency is fine, you can also watch movies without any problems with it. the few milliseconds are bearable and the sound skips fall also less.

everything is all a good adapter. despite the dropouts and the high, probably the royalties owed price, I would buy it again, since there is currently no alternative to APTX.
