This is a very reasonable headset for the £40 paid for it. It can be used on both ears quite easily. This can be done by twisting the over-ear piece to accommodate which ear is preferred. The button configuration on the headset is convenient for both left and right handed people.
I went for this headset because I bought a different Plantronics headset about a year ago and I could find no faults with it. So far, I can find no faults with the new 510. I find that the sound quality is extremely good, and it allows you to hear the conversation easily while driving along in the car.
Also what I find very convenient is the additional cable that allows you to charge the headset in the car from a cigarette lighter. In the box was also 2 other additional ear pieces, that can be changed for every ear.
It is lightweight and easy to carry around. For the reasons above I would highly recommend the headset to anyone who wants to buy a good headset at a reasonable price.
