I just started using the CQ1 headset. Similar design to Clarity Aloft/Halo. I really, really like it. Cords are far more robust than Halo, boom length is about perfect, and the volume control hardware just feels high quality and seems like it will last ages. Great audio, and the best part is the mic. I don’t have any hiss that you normally get with Bose or LS. On hot mic or off, there’s no difference in background noise.

It’s a better product than Halo and even CA (IMO), if you like the passive, forget-it’s-there in ear headsets.
