Review on Upgraded EM16 Bluetooth Earpiece, Wireless Bluetooth Earbuds 5.0 for Work, Single Earphone with Enhanced CVC8.0 Noise Reduction, 10 Hours Talking Time, IPX4 Waterproof, Hands-Free Bluetooth Headset for Phones/PC by Esera Warren

Every other bluetooth headphone/headset I've tried has hurt me. It doesn't seem to be the earbuds/headphones themselves, it's the signal. For some reason, this earbud doesn't. I can wear it all day (and it lasts all day) and I'm fine. I like the sound. I'm sure there are better sounding headphones out there, but I'm pretty picky about the sound and that's okay. The microphone seems fine. I don't get any complaints about being hard of hearing. There is no volume control on the headphones, but that suits me as well. It's not that hard, just a few clicks on my phone. One really great thing about these earbuds is the Bluetooth range. I can leave my phone next to a chair and walk around the apartment without any problems. No hissing, no pauses. Works perfectly!
