Model overview based on user reviews
The Panasonic RB-M300B headphones are praised for their exceptional bass and clear sound quality, offering a thrilling listening experience. They are comfortable with a reliable design, featuring swiveling earcups and a comfortable fit. The headphones boast a long battery life, lasting up to a week with regular use, and charge via USB-C. Users appreciate the intuitive control buttons and the ability to connect to two devices simultaneously. However, some users note that the ear pads wear out quickly and cannot be replaced, and the headphones do not automatically disconnect from Bluetooth, which can lead to accidental battery drain. Despite minor issues like the lack of a carrying pouch and the need to hold the button for a few seconds to switch songs, the headphones are considered a great value for money, with good sound isolation and a sturdy build. Overall, they are recommended for those seeking quality sound and comfort on a budget.

Headphones fit well. The only negative, they have a shutdown over time, but if you connected them to the bluetooth, then they no longer turn off, it happened a couple of times I forgot to turn them off so they lay on all night, but this minus is offset by long battery life. With my use for about 8 hours a day, I charge every 3-4 days, which is great! The sound is normal, for me. They connect to 2 devices (PC and phone) without problems, sometimes of course they get a little confused about which device to take the sound from (for some reason the phone is in priority), but this is solved by simply turning the music on and off on the phone, after which everything works with the PC. Fit well Battery No disconnection over time if connected to bluetooth  Vvvvbbgg Fvbb: use Panasonic RB-M300B few months |
The headphones are amazing. The first thing that struck me was how long the battery lasts. I used them for a week at work (listened for about 3-3.5 hours at full volume per day) and they didn't fully discharge. Good sound isolation. You can hear music in the subway and there's even a bit of extra volume. However, for some YouTube videos, the volume is somewhat lacking. The sound isolation is good, but you can still hear a car or motorcycle approaching from behind (which is good). I also liked the feel of holding them in my hands, you can tell they're high-quality and not flimsy, with the right weight, plus the wide metal plates inspire confidence. And, of course, the bass in the headphones is superb. The volume control buttons are convenient, and you quickly get used to them, although I don't use them often. It's still more convenient to switch music from the phone, especially since you have to really hold down the button on the headphones for a long time to skip a song. The microphone in the headphones is just okay, nothing more, nothing less. I'm not heard as well as with the phone, and it also picks up background noise. While talking on the phone walking along the road, there were no complaints from the other party. But in a noisy place, it's definitely better to switch to the phone. + Reliable design + Hold charge well + Good bass + Comfortable fit on the head + Control buttons are easy to find + Cable of suitable length and shape, does not tangle + Good sound isolation + Includes a microphone - To switch the song, you need to press the key longer than you'd like (approximately 3 seconds needed to hold the key down) - There is no carrying pouch included (I can't say it's a big downside, but still)  Katya Katetyaeva: use Panasonic RB-M300B less than month |
I bought these headphones on May 15, 2023, for 75 EUR. They have become much cheaper now, but I've been using them for almost three years, so I can provide an objective long-term evaluation. I got them for gaming, everyday use, and listening to music. Before this, I used on-ear headphones with about 8 hours of battery life - they would press on my ears and drain quickly. The main reason for the replacement was the weak battery. The claimed 50-hour battery life is accurate. I use them daily for over 5 hours, sometimes almost the whole day. I charge them every 2-3 days. After more than two years of use, the battery still holds well. The biggest downside is the reliability of the construction. About two years in, the horizontal hinges for adjusting the ear cups broke. Even though I used them carefully, didn’t throw them, didn’t carry them with tools in a backpack, and didn’t take them on trips. It was exactly those elements that didn’t look very reliable from the start that broke. I had to repair them with hot glue and electrical tape. They work after that, but I'm left with a bad impression. Another downside is the ear cushion material. Over time, the top coating layer (something like faux leather) began to peel off, leaving bare fabric behind. Functionally, it's not critical, but it loses its appearance. In terms of sound and battery life, these headphones completely satisfy me - they even exceeded expectations. But there are questions about the construction's reliability. If it weren't for the weak hinges, these would be almost the perfect choice in their class. Rating: 8/10 Long battery life, good sound, comfortable. not reliable design Dmytro Popovich: use Panasonic RB-M300B more than year |
