Plantronics Headset Flashing Red Light

Bright white light is very bright. Red/red-flashing light is cool -- not sure if I'll ever use it. Good fit and balance (with batteries in back). Lightweight and comfortable. Looks suitably geeky. Very happy with my purchase.

Paired it up with my Plantronics wireless headset and everything works great

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

I have a VERY OLD headset and M-12 base from long ago.  Unfortunately, the headset gave out.  But Plantronics still has compatible replacements such as the HW530.   B&H did their usual excellent support and had me a replacement within a few days.

It offers both a USB connection for my computer and a headset jack for my phone. I downloaded Plantronics software for my Windows 10 PC. I am very pleased with this product

I'm using this to replace a cheap in-ear headset that came with one of my Smartphones year ago. I could not believe how comfortable the new Plantronics would be. It's great for hour-long Google Hangouts/Meet and Zoom. People actually mentioned that my voice is much clearer and that there's very little ambient noise, even when someone else in the same room is on a call at the same time. The mute button only mutes on the headset but the volume buttons on the headset control the volume within Linux. I even like listening to music through it.

Purchased this to attempt to upgrade an old Plantronics USB headset with foam ear pads. I liked the foam pads because it didn't isolate outside noise too much which means sidetone isn't quite as important. Comparing these to those, these are more comfortable, but I haven't fully adjusted to increased isolation yet. The adjustment on the headset was pretty loose on one side and would adjust the height when taking the set off. I ended up removing the screws on that side and bending the metal piece to add some stiffness. It's lame that I had to do that, but it now works perfectly. Overall, I don't think I could have found a better headset for my needs, which are conference calls and music.

As usual, Plantronics serves up another terrific product. This is my second Voyager Headset and it's better than the first one I bought 8 or 9 years ago. Keep up the great work.

I purchased this to replace an older Plantronics headset with a failing, no longer supported battery. The CS540 lasts all day and has a far greater range than the one it replaced. It is a little difficult to find the right and most comfortable ear gel piece but I can wear it all day and not have a problem.
