Due to the nature of my job, I frequently receive phone calls while driving, so I needed a single-ear earphone and kept a spare. I no longer need it, so I'm selling it. I opened it to check if it powers on and works. I've used various earphones, but the EXPLORER 500 is the best for calls with one ear! - Model Name: EXPLORER 500 - Brand: Plantronics - Included: Manual, charging cable, ear hook - Condition: New (opened)
