Panasonic RB-M300 Wireless Over-Ear Headphones - Black (RB-M300BE-K) is rated 4.3 out of 5 by 28.
Rated 5 out of 5 by from Astonishing headphones. After a days of listening music through this wonderful headphones I could only say, Astonishing!! Great Stage Present, extremely defined instruments, with very natural and neutral performance. Bass is more than equal of any appropriate music, with possibility to give Extra more punch, who prefer. But if you want to hear REALLY, REALLY Astonishing sound, listen this headphones with cables. This is how start Magic, on this headphones... Capable to reproduce any kind of music, with nothing of make-up, like other Brands.. Unbelievable sound, for such a modest price !!! Very well made, nice and comfortable even for prolonged listening.. After all, WELL DONE PANASONIC !! STRONGLY AND HIGHLY RECOMMEND.

Rated 5 out of 5 by from Comfortable, Amazing Battery Life These headphones are pretty good for this price range. They aren't the most sleek headphones, however, the earpieces are pillow-like and comfortable and can used lying down without hurting, and are surprisingly lightweight. The battery life on these is the main reason I bought them in the first place and it did not disappoint. I can go about a week and a half to two weeks before having to charge them, and this with 3+ hours of daily use. The bass boost when on is subtle, but noticable and especially enchances and deepens older music.

Rated 5 out of 5 by from 2nd pair so must be good! I bought a pair of these for my daughter, Christmas 2022. She absolutely loved them! She found the heaviest and bassiest song in her library and boom!!! Fantastic sound. Really punchy bass, clear highs and mids. Unfortunately somebody stole them while at uni. She was gutted!! Christmas 2023 gave me an opportunity to replace them. She was made up!! Dad did good. 😊 Definitely a must if you are looking for new headphones.

Rated 5 out of 5 by from Phenomenal for the price. I have been using the same pair for almost a year, every day at work. I'd say 6 hours of continuous use per day, 4 days per week, with the bass setting ON, I have charged them less than 10 times. I compared them to multiple different other headsets and these came out on top. I wouldn't even bother going for the 500 or 700 series. They didn't outperform for the value. Excellent product Panasonic, one of the only things I enjoy at work is listening to these all day.

Rated 5 out of 5 by from Can't complain at all First purchase of Bluetooth headphones and I can they are comfy, sound is killer, and the noise canceling is good plus the bass option via switch is a nice addition when tryna cancel out voice and quite possibly blow your eardrugs out(to me, thats a good thing)

Rated 4 out of 5 by from So far so good These are really comfy and the noise cancelling and sound quality has been great. I wore them around the mall the other day and it was a gamechanger for me in terms of sensory overload and overwhelm. Highly recommend - especially at this terrific sale price.

Rated 2 out of 5 by from Great bass and volume. But easily damaged Bought this pair of headphones 2 years ago they were great. Great bass, Volume, and were comfortable. until they stopped charging, I cant power them on and the red light doesn't show up. Warranty just ran out a month or two before and i had to change brands.
