Good guide

"Good product. Took me an hour to fit. Your guide was helpful. Would have been easier if the battery case wasn’t broken, but some how it all went back together and works. Definitely appreciate the step by step guide."

— Adrian B. (5/5)

Highly recommend

"Made such a difference. Old cable was badly frayed and crackling. Like a new headset now again. Heard mixed reviews about the A30 so glad to keep my A20 working."

— John H. (5/5)

Saved over $300USD with this

"After the original cable came to its useful life. This replacement feels more robust and is relatively easy to fit. As the cables are new they’re a little stiff to get into the small cabling routes in the remote. Just persist with shaping it in. Excellent and just a fraction of the price of sending the whole headset off for a repair. Thanks!"

Bose A20 Gen 1 cable

"Perfect. Have received my cables and have repaired one headset. Great service, fast postage."

— David P. (5/5)

Perfect Replacement

"This isn’t the easiest repair. The part itself however is a perfect replacement. You have to make sure all the wires go back in their proper routing in the battery module to get it to close. I see no reason to upgrade to A30s and Bose should be ashamed of themselves for no longer supporting one of their best products ever. Thank you Hobbs Flyer for picking up the slack."
