The focus of Panasonic's RP-NJ310B is clearly on a strong bass reproduction, and the Bluetooth earpieces can handle this skilfully at both low and high levels. Advantages are the comfortable seat, the low weight, a credible running time and the quick charging function.

Product quality is average. I was expecting decent quality product at this price Most annoying part is, sometimes headphone turn off by itself and need restart

Pros:- Bass is pretty good but not great, Quite comfortable in the ears, audio quality on phone calls is good, tactile buttons Cons:- Long cable, not loud enough sometimes, no carry-case Verdict: This pair Bluetooth earphones may not be for those looking for powerful bass and serious workouts (not the best grip on your ears).

This product is great for the price, the sound quality is good the battery life is great and they are very comfortable in the ear - I recommend these headphones

Bluetooth connection is great. Great sound & lasts a long time. (Highly Recommended)

Paired easily with my S20 though takes about 5 seconds to pair once turned on. They won't pair with my Amazfit GTR2 which is a shame. Sound is good and has decent bass. I was looking for wireless headphones and these have worked out well. When you power them off a recorded voice tells you how much charge is left high medium low etc. which is a nice touch. Charge time is as advertised. Playback time is also as advertised. Comfort level is pretty good - these where a step up from the standard issue headphones that came with the S20 - for comparision these panasonic earpieces feel comfortable.
