[Q]: I bought a pair of these at first and one has stopped working just after the return day. They sound great while they work but if you want headphones that will last you buy something else. Also tried to get in touch with customer service twice for this issue, only got an answering machine most times. Not worth trying since they were never able to send me another headset to make it right. I'm done returning them. Amazon took care of them quickly so I give them five stars.
[A]: Bad review


[Q]: I've been in an office environment with this product for a week, and am looking to see how long the tip will last before failing. The rubber is starting to pull away, showing some signs now of cracking, I only use the tool occasionally but it should not be failing so soon. Too bad cause it's perfect ergonomically otherwise. A very high defect rate on mine makes me think that's just the nature of the beast. Would love if they could re-design it.
[A]: Bad review


[Q]: I bought it to my mom and she's been enjoying it. The battery last for couple of weeks, she has a very large area, but only 2 dogs so it's fine
