Apple AirPods

Episode 1535

Chris from Miami, FL

Chris has the new iPhone XS and the wireless Apple AirPods, but he keeps getting distortion when he takes calls. Not when listening to music or watching video, though. Leo says that Bluetooth headphones have two different modes. There's a mode for use as a headset for calls and A2DP. A2DP is stereo and was designed for listening to music. Headset mode uses the minimum bandwidth possible. So that could affect it. Also, a phone call that is routed through the internet can be full bandwidth and it may be that the AirPods just can't handle it.

Episode 1502

Jim from Lakewood, CO

Jim just got a new Honda and he can't get his MP3 player to pair with it via Bluetooth. Leo says that if he can connect his phone via Bluetooth, then it supports Honda's version of the A2DP standard. The question is, does that MP3 player support it? It may be that Honda doesn't properly implement A2DP. Most cars will pair with an A2DP standard, and if his MP3 player supports it, then it should. But since that car has Apple CarPlay, he can always use his phone to stream music.

Avis from Santa Ana, CA

Avis has a Sony LCD TV and she says that she's having trouble connecting her Bluetooth speakers and home theater to it. They work with her tablet and mobile phone, but not her Sony TV. Leo says that Sony doesn't put the A2DP Bluetooth profile in the TV OS (although this year's models do). That's probably why it can't pick it up.

Episode 1158

Vlad from Walnut Creek, CA

Vlad wants to be able to play streaming music from his phone to his car stereo. Leo says that if he has a stereo that has Bluetooth support, then he can do it via A2DP. But if he doesn't have Bluetooth support, he can get audio through the lightning connector. If his stereo has USB, Leo isn't convinced that he could route it through Android's microUSB port.
