I purchased this headset to use with my Motorola Q to replace another headset that simply was a piece of junk. The BT5010, which has Version 2.0 Bluetooth, initially was uncomfortable but after I finally figured out how to make the adjustments it is comfortable enought for me to keep on all day. It paired up very easily with my Q without error. I have had it now for a month and overall I am still very happy with the headset. The sound is clear and the sliding boom is a feature that I very much like, it makes it very easy to make and answer calls. You can also wear the headeset on either ear. I must admit that the vibrate in the ear for incoming calls was something that I had to get used to, but I can assure you that you will never miss a call. I would highly recommend this headset to anyone, overall this headset was a great choice and one that I would make again.
