if you know nothing about cars and/or have no experience installing parts on your car, do not be fooled by the ?easy-install? tagline. Overall though, its the best Ive found in this style and price range, and the little touches make the difference. Instead I received Poly branded headset. I got these for 20k during the sale but still unacceptable. It is not a dealbreaker for me, and I will be keeping them. I have given a couple of these things as small gifts. It looks like the soles are a right and a left but the tops are both rights or both lefts each time. -----------------------------------------------------------------UPDATE: After Almost 4 Months of Use1) Connectivity QualityAs I mentioned in my initial review, the headset has a tendency to drop and pick itself back up again. I was very impressed with these tbh, wasn?t expecting a whole lot but they exceeded expectations. Again, Im still just getting into the hobby, but the clarity is definitely much-improved with this stylus.
