Sony MDR-XB50BS Review

Sony MDR-XB50BS Review

The Sony MDR-XB50BS are their new wireless in-ear headphones designed for working out. But that’s not the only reason to consider buying them. They are also advertised as bass heavy headphones and they come with a relatively inexpensive price tag. Which on paper makes it perfect for working out! So let’s see if that’s actually the case as well.

In The Box

  • Sony MDR-XB50BS
  • 3 sets of ear fins
  • 4 sets of ear tips
  • MicroUSB to USB charging cable


These aren’t exactly the smallest wireless headphones. I’d say that in terms of size, they are around the same as the Beats Powerbeats 3 Wireless headphones. But surprisingly the Sony MDR-XB50BS weigh much less and are also more comfortable. The size also comes with a positive side. The larger footprint also means that they also stay in your ears better.

For that, Sony has also included some extra ear tips and fins in different sizes. There are actually 4 sets of ear tips you can choose from: SS, S, M and L. They provide a really nice tight fit and that’s exactly what I’d hope to get as well. Not only does that help at keeping the headphones in your ears, but it also improves the audio quality.

Sony MDR-XB50BS Design

The audio can be controlled from the right earpiece. It has 3 buttons for changing the volume and pause/play. There is also a MicroUSB port for charging the headphones. This is also why I like the size because the controls are actually easy to use. Oh and another thing that I really like in terms of the design is the cable. It’s a rubberized flat cable that’s really durable and you don’t have to worry about it breaking.

If it’s possible, then I do recommend trying on these headphones first if you are buying them for running. I personally haven’t had any problems with them slipping out of my ears as the fins fit me perfectly. But I have read different experiences where the fins haven’t locked into a persons ears tightly. They are perfect for lifting weights at the gym though.

Wireless Performance

It’s easy to pair the headphones to your phone. Just turn them on and connect via bluetooth. Once they are paired, they will connect to your phone automatically. If you wish to connect them to a different device, then you need to reset them. The overall wireless performance is fantastic. The wireless range is around 10 m / 33 ft. And the audio quality remains crystal clear at even those distances. So you can easily walk around the gym without having to have the phone on you.

Sound Quality

The Sony MDR-XB50BS wireless headphones have a pretty impressive audio quality. They sound especially good when you listen to EDM or Hip-Hop. Basically anything that is bass heavy. Sony even calls these the Extra Bass wireless headphones and I have to agree with that. It has a decent amount of punch and stays good even when you turn up the volume. So these are definitely good for people who like bass.

The in-ear headphones also have a built-in microphone. So you don’t have to take them off while someone is calling. The call quality is fine but I wouldn’t use them in a noisy environment.

Battery Life

It takes around an hour to fully recharge the built-in battery. A fully charged battery should give around 8 hours of continuous music listening. Which is really good considering the price of these headphones!


If you are looking for high quality wireless sports in-ear headphones without having to spend too much, then the Sony MDR-XB50BS are the ones for you! Sure there are cheaper options available as well but those are usually by no-name companies. With Sony you know exactly what you are getting.
