Microphones

Blue Yeti Mic

works very well, but no built in noise cancellation so it picks up everything unless you use it in Cardiod mode with the gain all the way down.

Bluetooth Adapters

1Mii USB Bluetooth Audio Transmitter B10 EAN X0014UJEH3

Function:

• for computer it is just a USB "sound card"
• internally, it transmits sound output via BT5 to headphones speakers
• internally, it receives sound input via BT5 from headset microphone
• 2 modes, switch by hw button:
  • music - high quality (aptX) - output only
  • call - lower quality - input/output

Pros:

• just a soundcard, keeps all the BT stuff away from computer
• nice for Qubes OS (just forward USB device to VM with teleconf sw)
• nice for Linux and BT5 (not [m]any working BT5 adapters yet)
• some stuff "just works"

Cons:

• lots of states signalled via single multicolor LED
• misc. state changing inputs via a single hw button

• powerful processing / mixing / assembling of video output signal from misc sources

Con:

• to emulate a virtual webcam (which then can be used by your video conf software)
  • you need an extra plugin and a kernel module and you might need to compile some stuff.
