Question: Can this headset be used in either ear?
Document: I have long requested a headset for my desk at work and finally talked them into it. I love this headset. Of course, being the first I have ever used, I really don't have anything to compare it to  but I have no complaints. However, if I had to come up with one negative, it would be that I can't place a call on hold using the headset. Other than that, I love it!!
The worst part is that when the lifter goes down. The handset doesn't always hang up properly. And I've used up all my adhesive stickers so I will probably have to order more.As far as call quality, if I turn the ear piece volume up high enough to hear easily, there is a horrible echo.
Great unit - still getting used to it, but very comfortable earpiece, easy to use. Recommend it to anyone who is on the phone as much as I am.
Product doesn't work well...When making calls, the person on the receiving end can hear their voice very loudly and there doesn't seem to be a cure for this problem. We have discussed it with other colleagues who also have this headset, and they have said the same thing happens to them. Not sure why this is, but I would not reccommend this product.
I have to power off-on this unit 1-2 times a day - since the mic seems to get weird at times. I have tried the higher quality mic settings and this does make a difference - but I sound somewhat mechanical at times. The headset makes it for my 8 hour day - with no problems - which is better than the other Palntronics I had - as it would only last 4-5 hours.
I've had this device since March of this year, so about 6 months. Device works great with my home office phone (a Panasonic unit). My only complaint is the charging cradle. I don't do that many office calls, but sometimes when I drop the headset back into the cradle, I don't always get a good contact and it fails to charge. Wish the design of this device would have better connections, but that's really the only complaint I have with the system.
Great sound quality, easy to use. Just a little difficulty changing the ear pieces. It was easy to set up and start using!
Lightweight, very easy to assemble the entire unit. We are extremely pleased with this product and our choice. Very clear crisp line I praise this ear piece!
User happy with operation, lift sometimes failed to lift completely but changed location which improved performance. Even though be prepared for ear irritation with high volume.
I need reading glasses when at my computer (bifocals in other situations) and getting the battery part set correctly behind your ear takes a little practice unless you remove your glasses, put it on, and replace the glasses.
Answer: Yes it can!  The earpiece has 3 pivot points allowing it to go on either side with the boom still positioning naturally as well as the earpiece fitting properly in either ear.
