Bought 2 pairs. One works perfectly, but the other has trouble connecting to Bluetooth. When it does work, it only lasts for an hour or so.

Not rechargeable!!

It fits way too tight, but worst of all is that it uses standard batteries. I would never have bought it if I had realized I would need to feed it batteries.

I use the Defy Slims every day. I’m an independent contractor so I’m experiencing loud noises at least once a day. I wore my first set of ear pro out after about 18 months. The Bluetooth would not connect. I reached out to support and received another pair free of charge! Then after another 18 months or so the wiring started to go bad on the free set. I just bought another pair and I’m looking forward to wearing them this summer as work will start picking up again.

The bluetooth performance is sketchy and I have so much interference. Also volume seems very limited I would really like to return them Is that possible
