Review on 🎧 Plantronics Blackwire 3320 USB-A Dual-Ear Headset with Boom Mic – Ideal for Teams, Zoom & More! by Robert Staten

I opened the ECU to see what the problem is. One of the micro thin (like cheap, low quality) wires broke off at the solder joint. I stripped a small piece of wire, but the tension on this now shortened wire was too great and it snapped again immediately. Plantronics was kind enough to put a resin seal on the stopper knot at the end of the harness so you can't unwrap it to expose more wires without destroying the wires. I bought a Plantronics headset about 15 years ago which was solid and still works. . It's a shame to see such a cheap product today.
