Voice calls are nice and clear. It fits well in small/medium ears (tested) with no issues and it charges quite quickly. Overall, it's a very nice headset for a good price. Some Plantronics headsets have some issue, but this has been fantastic.

Love it

Clear Signal; Connects Easily; Fits well in ear; Good Sound; Good Volume Control; Lightweight; Long Battery Life; Noise Cancellation

Nice product and lives upto everything that was in the description

The headset work as advertised! The strap though leaves much too be desired. I purchased mine back in 3/2017. The strap refuses to charge my headset. It is not covered under warranty. Fortunately for me I found an old USB cable lying around that fit the earpiece.

I am very satisfied with this bluetooth, but I have to change it every 6 months, because the plastic cover of the button snaps out. I am good for the first year (warranty-replace), but after that period, I will be out of luck.

I regret discarding the packaging for this headset. "Breach of warranty of fitness for a particular purpose" is the phrase that comes to mind for the Explorer 500 Mobile Bluetooth Headset.

Worked for 1 month before the speaker died. Now I can hear people but they can't hear me. Useless.

I bought this as i spend so much time on the phone (at desk and driving) so i really need to be able to go through documents while also talking. The ease and sound quality of this is amazing. The rubber thing makes it fit into my ear so easily and doesnt get sore.

I'm glad Plantronics is still making bluetooth headsets as they seem to be getting more and more rare these days (many other manufacturers are focused on making truly wireless buds for music instead, and unfortunately a lot of them are not great for calls) My Explorer 500 works as expected.
