Question: Excellent product. I was having difficulty hearing and also getting a comfottable fit with the included ear hook that came with my Jabra JX-10 Series II Bluetooth headset. I removed the hook and attached one of the 6 gels that came in the pack to the headset and found that the volume increased 40% and I was able to achieve a comfortable fit. The headset is small enough and light enough that the gel holds the headset in the ear. I was about to give up on this headset (and all earhook type Bluetooth headsets) prior to getting the gels. If you are looking for a comfortable (and econimical) alternative for earhook type headsets, I strongly recommend that you give these a try. They are well worth the price.

Answer: Positive

Question: I bought this adapter almost two years ago and it still works-kind of. The insulation on the area of the cable where it enters the brick has become damaged, exposing the outer wire. I taped it up, but there is always a connection issue, where the AC indicator at the top of the screen will often flash to battery power and then back to AC. I keep the AC adaptor in the front compartment of my backpack, so it sees some but not major abuse. I'm sure this won't be an issue if you aren't traveling with it, but I just thought I would relate my experience.

Answer:
Negative
