I purchased a Lightspeed Zulu 2 recently, but i found that the left ear had a buzz in it whenever the ANR was turned on. I contacted lightspeed about the problem and they were extremely friendly. I received a pre-paid shipping label via email and only had to pay 3 bucks for the packaging. Lightspeed offered to replace my headset with a new unit or repair the existing one. I opted to go with a new one and i received the new headset within a day of it being shipped out of their warehouse via "UPS next day air" . I tested the new unit and found it to be fault free (no buzz) and very comfortable. yet to use it in the airplane. I highly commend lightspeed for their friendly,speedy and committed customer care. Would recommend the headset to anyone interested in it.
Hope this helps
