Bose. For the product and customer service. I've had mine for 2 1/2 years and will never own another.
I actually sent mine back to Bose two weeks ago for some minor repairs-started going through batteries every 10-15 hours vs. 35-40 I had been getting. They rebuilt the headset. The only original parts that came back were the actual ear cup.
I did own a Lightspeed 30-3G. The most expensive piece of junk I've ever owned. Heavy, clamped on my head pretty tight, over sized ear seals were too big and uncomfortable, the smaller ones collapsed and the noise canceling would get to close to my ear causing feed back. Twice the headset just died. No passive, no active-nothing. I called Lightspeed and they sent the parts to me to fix-which required the removal of the plug ins which required me to dissasemble the headset. Oh, and they sent the parts Parcel Post.
