Decient headset 11/21/2013 8:15:32 AM

Pros: We have a number of these headsets in our call center. We have very few issues with them. If you put them on charge during lunch they will make the whole day. Unlike some earlier model we rarely have to re-sync these to their base.

Cons: The batteries last around a year and are expensive if you need to purchase a lot of them. Though this is the same for other headsets we have used as well.

Overall Review: Steer clear of the cheap replacement batteries. They won't get you through a whole day.

YOU SHOULD GET WHAT YOU PAY FOR 10/21/2013 11:22:12 AM

Pros: Lightweight, nice design.

Cons: Callers complain of feedback (hearing themselves) - untouched by relocating base, or adjusting settings). Within six weeks, callers began to sound like they were underwater, and volume was dramatically lower; again, no amount of relocation or adjustment would resolve issues. Final insult: the length of time it will hold a charge has decreased. I use for 5 hours, put headset on charge for one hour while I go to lunch. The first month, it worked fine for afternoon 2.5 hours. Now, it starts beeping at 1.5 hours. Bottom line, this was too much to pay for a headset that could only perform as advertised for ELEVEN WEEKS.

Overall Review: Full user's guide not included.

Pros: Lightweight. Easily converts from over-the-ear to over-the-head set up for other occasional users.

Cons: Outside callers frequently sound like they are underwater. Internal callers complain of feedback, have to hang up and call again. Base-to-telephone or base-to-computer relationships make no difference. Normal headset use is 5 hours, 1 hour on charge during lunch break, then another 2.5 hours of use. After first 85-90 days, this unit stopped holding a charge after two hours in the afternoon. This week, sound volume has dropped; I am constantly adjusting the earpiece to try improving reception.

Overall Review: Package did not include a User Guide, only a Quick Start Guide. Is this supposed to be a contribution to the "light-weight" claim?

Plantronics CS540 10/12/2012 2:30:28 PM

Pros: Light. Good volume control.

Cons: Totally agree with the previous review. Lacks information on the product and its futures. No dialing pad. Very expensive. Not worth more than $100.

Not enough info provided 9/26/2012 11:21:15 AM

Pros: Looks nice, but I cannot tell if it is compatible with my existing desk phones because the pictures and details provided by newegg are incomplete. Hopefully they will update the pictures (of all the plantronics devices) with images of the plugs and all of the included wires. I am not purchasing this item today only because there is not enough information about it here.

Cons: How do you plug it in? I could tell if there were pictures!

Overall Review: Other websites have even less information so I am not sure who is to blame for the lack of useful information on Plantronics headssets.

Extremely Easy to Use and Comfortable 4/19/2012 12:08:07 PM

Pros: This system is both light and extremely easy to setup. It also works great with the HL 10 Lifter. I was impressed by how simple it was to connect and operate. This headset comes with multiple ear pieces and the ear hooks so it can be adjusted even for the smallest of ears. It also has an adjustment on the base of the headset that swivels back and forth to make the headset easy to put on and get off.

Cons: none so far
