Great sound quality, highly adjustable/customisable fitting for the head/face. Note that you'll need a HL-10 hook lifter for simpler phones or a cable to connect to EHS-compatible phones.

I have enjoyed my Plantronics headset. I am having issues with volume on both ends of the conversation. The headset occasionally needs to be tapped in order for me to be able to hear my conversation.

We just bought our twelfth Plantronics headset and we only buy Plantronics at my company because of the reliability experienced over the years. We bought our first CS540. Excellent quality.

Love this headset. Only issue, which is not a big deal is...when you place on the charger you have to somethings wiggle it to make sure it is locked in to charge. Not a big deal for what the headset provides. Would recommend it!

Took longer than noted to charge and use. Once finally charged and used, all users on the other end of the phone get an echo with every word they say.Very expensive piece of equipment on my desk that is currently unusable. Waiting for plantronics to respond to my email.

very good construction quality.comfortable for everyday use.

great quality product

nothing when on sale

I was having a serious problem with earpiece volume being too loud on my digital office phone, and the telco experts finally said to "get a headset." I had tried them in the past and hated them. But I gave this Plantronics 84691-01 model a try, and after a month of use, I'm keeping it.

This was bought for me to replace an older Plantronics headset. This one is much more stylish, very light & comfortable to wear, and it has great sound quality. Works with existing HL10 handset lifter, which means I can pick up calls away from my desk. Really good headset, would definitely recommend

Easy to use; Looks good/design; Sound quality; Easy to set up

Good quality, good range, and easy to setup. The prices are good at Headsets Direct, but I also like the fact that they are here in the US. When I call them, I am answered by a person instead of a host of menus, and their reps speak real English. Shipping is also very fast.
