Bluetooth isn't that bad anymore, not great but not terrible. Sound quality has gone up dramatically and latency is now tolerable. What really blows is that it's still not really capable of sending lossless 1.4 Mbps uncompressed PCM CD audio so your music must be stored as uncompressed WAVs if you want good battery life and exceptionally good lossy output sound quality on your headphones.
