Revision history [back]

I tested two Jabra devices with the Jolla.

1. Jabra Halo 2 headset: audio quality for music playback is sub-par. This headset works perfectly with two Macs, an iPhone 4S and an iPhone 5S but is below average with the Jolla.

2. Jabra BT-3030 headset adapter: this adapts wired headphones to bluetooth, contains a mic and remote controls. Works perfectly with the Jolla.

Since the BT A2DP profile specifies a variety of codecs, including one with DRM, I suspect that in (1) above, the Jabra Halo 2 connection is dropping down to a low performance codec. This may be a compatibility issue between the Halo 2 and Jolla.
