Greetings.
I recently bought a pair of bluetooth headphones, August EP650. They work perfectly on Windows 7, no skipping, great quality. However, in Arch they play ok for a few seconds and then start to skip badly and lag behind (for example, if I pause whatever I'm hearing, I only hear it pausing a few moments later).
I googled hard all day yesterday to try and find a solution but no luck so far.
The logs keep spewing this

I'm using the latest pulseaudio and bluez, pairing and connecting using bluetoothctl.

Hello jpgrego,
Try downgrading to bluez4/pulseaudio4 in aur . Bluez4/Pulseaudio4 works perfect for me with Nokia BH 503 but in *Debian Jessie/ubuntu 13.10/14.04, I have no tried on Arch because I don't like downgrade things and i was using Gnome3.12 where bluez5 and pulseaudio5 is a dependency

I had those problems for months on my laptop. Perfect bluetooth audio experience on Windows, unusable on Linux. It finally got solved with bluez-5 and pulseaudio-5. So it may come down to poor bluetooth support for your current chipset.

Already tried that, didn't help though unfortunately... thank you for your suggestion anyway!

Yeah, I suspect that's it. My bluetooth adapter is embedded on the wifi adapter, so they're both from Broadcom (BCM4313) and god knows the problems I had with wifi already. Broadcom doesn't seem to have good support for linux.

I've had this problem for months and months and *finally* found the cause and the solution. Through using kinfocenter (KDE app -- lsusb could be used as well), I noticed that my USB keyboard, USB mouse, and USB bluetooth dongle were hung off the same USB host controller. The mouse and keyboard generate lots of tiny packets and tend to dominate the bus, which leaves the bluetooth dongle locked out frequently and thus unable to send the large packets of music data. Moving the bluetooth dongle to a different USB port attached to the second USB controller on my computer completely solved the problem for me. No more "[bluetooth] module-bluez5-device.c: Skipping" messages and smooth audio playback. Good luck!
