Re: [iPhone] Bigger Fail Than Maps ...If the headsets used WiFi or high profile PAN for their connectivity, great, but they use A2DP (at least all the ones I use) and it's a spectrum hog, 768kbps of a 1-3Mb BT2.1 capacity of which you can use 320kbps for actual audio transport as part of the standard; I'm assuming to permit substantial overhead for retransmits etc.
So while THEORETICALLY you could use that channel space to get decent audio, in practice you don't and the devices set default bit rates in the crapper which is why I stated you can improve quality by changing those default settings in some cases but even then, you aren't going to get good quality from 'em. In practice with the transcoding they'll have 128kbps quality. Not unlistenable but far from great.
Where are you getting 3Mb per channel from BT? BT 2.1 is 3Mb TOTAL from what I've read with 3.0 pushing 24Mb total as you describe. |
