Panasonic RB-M700B Headphones Review

Bottom line

The Panasonic RB-M700B offer clear and present audio, as well as distortion free bass that you can feel. The headphones also provide active noise cancellation for a price which would be worth it even if either of these features were not satisfactory.


Pros
  • You have complete control over the extra bass
  • Comfortable fit
  • Bluetooth 5.0
  • USB-C charging
Cons
  • Active Noise Cancellation is mediocre
  • Plastic build that doesn’t feel durable

Design

The RB-M700B headphones are a very handsome set of headphones. But they’re probably not what you want if you’re looking for flashy and sophisticated style!

The RB-M700B are over-the-ear headphones that use a single headband to secure them to your head. The band is sturdy and flexible, but still doesn’t feel like the sturdiest of materials. The ear cups are lined with memory foam that makes the headphones soft and comfortable to wear for long periods of time. You can adjust the headband for a perfect fit and it’s designed in a way that doesn’t allow the headphones to slide around on your head.

The RB-M700B headphones come with a micro-USB cable for charging the headphones as well as an audio cable with a 3.5mm plug if you want to use them in wired mode. The RB-M700B also comes with a nice hard shell carrying case that has a mesh pocket on the inside of it to store the included audio cable as well as other small items.

Comfort & Fit

The RB-M700B headphones feature very soft ear pads that will not cause any discomfort when wearing them for long periods of time. The headband is also padded with a soft material that will not put too much pressure on your head, even if you decide to wear these for extended periods of time without taking them off.

The ear cups are big enough to cover the entire ear and are very comfortable to wear. The ear cups also swivel to allow for a better fit on different sized heads.

The headband is adjustable so you can find the perfect fit for your head. It is also made of metal and feels very solid, unlike the plastic found on some other headphones that tend to break easily after extended use. The RB-M700B headphones have a solid build quality that you can feel when you take them out of the box.

The RB-M700B headphones have an adjustable slider on each side of the ear cup that allows for more room in case you are wearing glasses with these headphones or if you have a larger than normal head. They feature a folding construction which makes them easy to store when not in use.

Features

The Panasonic RB-M700B comes with active noise cancellation, Bluetooth 5.0, USB-C charging, as well as NFC for quick pairing with compatible devices, such as smartphones. It also has an integrated microphone for taking calls and voice commands on compatible devices.

Performance

Panasonic’s RB-M700B is built with powerful 40mm drivers which are capable of producing rich bass without sacrificing clarity of the mids and highs. They’re not the most powerful headphones, but they pack a punch for their size. The bass is deep, accurate and sounds great. The low end is present and punches hard when called upon. Listening to music with the RB-M700B is a pleasure as they are capable of producing rich, clean audio that doesn’t sacrifice fullness of sound or clarity of the mids and highs in order to get the low end right.

The mid range is clear and detailed without being too harsh on vocals, which was an issue we had with the Panasonic’s RB-M700B headphones. They are able to reproduce vocals accurately without making them sound shrill or like they have been run through a processor to make them sound unnatural.

The highs are crisp and clear without being too bright or harsh on your ears. Listening to music with these headphones will make you appreciate how well made they are as you hear details in songs.

Audio Quality

The overall audio quality of the RB-M700B headphones is average. They are not going to blow you away with their sound, but they do a decent job of providing clear and crisp sound without adding too much of a bass boost or distortion.

The highs on these headphones are pretty average as well. They do not have any problems with sibilance, but they are not very detailed in the upper frequency range. The midrange on these headphones is also pretty average as it does not have any problems with sibilance or being too bright or muddy sounding either. The bass on these headphones does add some extra punch to the sound, but it is not overly boosted either.

While the performance of the RB-M700B headphones is decent overall we did have some issues with their audio quality. We found that they tended to have some minor issues when it came to high frequency sounds like cymbals and bells in particular as they were often slightly muffled or distorted sounding

The bass reactor mode on the RB-M700B headphones is pretty decent. It does help to add some extra bass punch to your music without adding too much distortion, but it is not overly boosted either. The bass on these headphones does provide a good amount of thump and impact, but it does not feel overly powerful or boomy.

Battery Life

The RB-M700B headphones have a rated battery life of 20 hours of playback with the Bass Reactor off and the ANC on. This is a huge improvement over the Sony MDR-XB950N1 headphones which had a rated battery life of only 8 hours. The 20 hour battery life is the most we have seen in a pair of Bluetooth headphones so far and will last you through multiple trips to the gym or even several days worth of commutes to and from work.

Noise Isolation

The noise isolation on these headphones is mediocre. If you are in a noisy environment, like a subway car or in the middle of a busy street, then you will not be able to block out all of the noise and still be able to hear clearly.

The level at which the ANC blocks out noise is also rather mediocre. The ANC is only able to reduce noise by 3dB, which means that it will only reduce the volume of outside noises by about 10%. This means that if you are playing music at a moderate level, like 65% volume or higher then the ANC will ensure that you can still hear what is going on around you. If your music is at lower levels than this then you might end up missing out on some sounds because they are too quiet.

The ANC will also not block out all frequencies of sounds. For example if there was a fire alarm sounding off in an adjacent room or people talking outside your door then it would not be able to block out all frequencies.

Microphone / Call Quality

The microphone quality on these headphones is average. We were able to clearly hear our callers, but they said we sounded slightly muffled or distant and that our voice was sometimes hard to understand. The microphone also picks up background noise easily so make sure you are in a quiet place if you plan on making or receiving calls.

Controls

The controls on the headphones are fairly intuitive with the right ear cup having three buttons and the left ear cup having two. The buttons on both ear cups are large enough that you can easily find them when wearing them and they are also tactile so you know when you have pressed one by feel.

The right ear cup has a power button, a volume up and down button, and a Bass Reactor mode toggle button. The Bass Reactor mode will allow you to enhance the bass levels in your music if you want to boost it or if you are listening to something where there is no bass to begin with like classical music or podcasts.

The left ear cup has a multi-function button which is used for pairing, play/pause, answering calls, rejecting calls, and ending calls. There is also a microphone built into this side of the headphones so that you can use them for taking phone calls as well as for using Siri or Google Assistant.

Wireless Range

The RB-M700B headphones have a wireless range of 33 feet which is more than enough for most situations, but there are many pairs of headphones out there with much larger ranges if you need them.

Conclusion

Since I have been using the Panasonic headphones for the past few weeks I have been able to test them out on a number of different types of music. When listening to electronic music like dubstep and house music, I was able to hear all of the deep bass that was present in both songs.

The sound quality of these headphones is very good and is easily comparable to other models that cost more than twice as much. The bass levels are not overwhelming and you can still hear some detail in the bass even when listening at high volumes. The mids and highs are also very clear which is good since most people listen to music with their headphones on a daily basis.

The Active Noise Cancellation of Panasonic RB-M700B is mediocre at best, but is still good enough to drown out the loud noises of a busy city. Although you can still hear some sounds that are around you like conversations and people walking, it is not as bad as other models that I have used in the past.

Overall I think that these headphones are great for the price and I would recommend them for anyone who wants to get headphones that sound great and have a decent amount of noise cancellation.
