-====== What? ====== 
-Just some notes around the Bose QuietComfort 35. 
-  * pro: wireless: bluetooth profiles for headset and High Fidelity playback (A2DP) 
-  * pro: quite good noise cancelling 
-  * pro: build in rechargable battery 
-  * pro: simultaneous connections to 2 bluetooth devices possible 
-  * con: when the cable is used, only headphone functionality is available. No microphone signal goes over the analog cable. 
-  * con: after 45min of wearing, I need to take the headset off 
  
-====== bluetooth profiles ====== 
-bluetooth profiles supported by the headset: 
- 
-  * Advanced Audio Distribution Profile (A2DP) 
-  * Hands Free (HFP) 
-  * Headphones (HSP) 
-  * Audio/Video Remote Control Profile (AVRCP) 
-  * BTLE (Bluetooth Low Energy) 
- 
-Currently I can choose between pure Audio output (A2DP profile) in good quality, or hearing/​listening (HFP/HSP profile) with lower quality. HFP in version 1.6 seems to also support better audio transport. The bluez5 implementation on Linux seems to support HFP v1.6 and HSP v1.2 ([[https://​git.kernel.org/​cgit/​bluetooth/​bluez.git/​tree/​doc/​supported-features.txt|reference]]). Not sure how to see which version is used for communication with the headset. ​ 
- 
-"​Hands-Free Profile (HFP) Version 1.6 adds optional support for wide band speech with the mSBC codec, a 16 kHz monaural configuration of the SBC codec mandated by the A2DP profile."​

-===== fixing HSF/HSP bluetooth profile ===== 
-When connecting the Quietcomfort 35 to my Thinkpad x230, I was able to listen music with the A2DP profile. Yet, selecting the HSF/HSP, I did not hear anything/​was not able to use the microphone. This message appeared in the logs: 
-<​code>​ 
-bluetooth hci0: Direct firmware load for brcm/​BCM20702A1-0a5c-21e6.hcd failed with error -2
