Sony MDR XB90EX In Ear Extra Bass

If you are someone who can’t get enough bass, the Sony XB950B1 was built with you in mind. Not only does it offer incredibly powerful bass, but the bass is adjustable, allowing you to fine tune the amount of low end delivered to fit your personal preferences.

Add in wearing comfort, the freedom of Bluetooth wireless connectivity, and other features such as built in mic and onboard controls, and you have a bass centered headphone that not only sounds good but is packed with features as well. In additional to all of this, the XB950B1 also includes app control for Android and iOS devices, giving you more control and flexibility than ever before.

Check out the following Sony XB950B1 review and see why this headphone is a feature packed bass monster that will satisfy even the most discerning bass heads.

Pros: Comfortable; lots of bass; good overall sound; fun to listen to; built in mic; additional functions available via the app; virtual surround sound; onboard controls.
Cons: A little on the bulky side, although in fairness this helps with the bass projection. They are not the best choice for portability.

The Sony XB950B1 offers thick foam ear cushions that are comfortable to wear without being overly heavy. The padding on the headband and the oversized earpads are super comfortable and do a great job of relieving pressure on the ears and temples. They also feature the added bonus of minimizing vibration which results in a tighter seal, minimal vibration, and more powerful bass.

The heavily padded earpads stick out farther than most headphones but I don’t feel they get in the way or are at all uncomfortable to wear.


The Sony XB950B1 seems to be solid and well built. They are not on par with some of the more expensive Sony headphones I have tried, but this is to be expected. For the price, they are well built and will stand up to daily use and the occasional bump or drop.


Sony MDR-XB90EX BoxedIn terms of features, the Sony XB950B1 does not disappoint. The model I reviewed features a stable and easy to pair Bluetooth connection with a ten meter range. Battery life is up to 18 hours with the bass boost on. When it’s time to recharge, connect the included USB cable and the headphones recharge in about 4 hours.

A built in microphone allows you to make and receive calls without reaching for your smartphone. You can also use the mic to give voice commands to your smartphone.

Onboard controls are also included which allow you to adjust volume, pair, turn bass boost and surround on and off, play/pause, and skip. The coolest feature, however, is the additional controls that come from the app. With an iOS or Android device, you can use the app to adjust the bass levels and choose between presets.

While most headphones either have a bass boost that is permanently on, or one you can turn on or off, the XB950B1 allows you to customize the bass to your particular needs. This is an especially great feature because not all types of music require the same amount of bass.

There is also a virtual surround setting which can be used to add additional ambience to your listening experience.

If you want to conserve battery power or if you run out of battery, you can use the included 47 inch detachable 3.5mm cable to use the headphones wired. Features which run on battery power such as the built in microphone will not work when used in wired mode.

Sony has also included voice prompts in the XB950B1. A clear and articulate female voice informs you of things such as when you’ve powered on the headphones, turned the bass on and off, etc. This is a handy feature which keeps you from having to continually take the headphones off to look at the settings.

How good is the Sony MDR-XB90EX for Sound?

Bass heads will love this headphone as it provides a powerful low end response that is as customizable as it is deep and powerful.

With the app you can fine tune the bass to your particular needs, even turning it down into the negative areas, making them sound more like a flatter conventional set of headphones. This is a nice feature, since there may be types of music which don’t require as much bass. It’s nice be able to turn the bass boost down if you’re listening to a podcast, for example.

If you love bass, this headphone can easily go from neutral, to boosted bass, to more bass than you could ever want! Even with the bass all the way up, the headphone still sounds clear and doesn’t distort. There is also enough volume on tap for any situation.

The highs and mids sound good as well, but this headphone is definitely designed for bass. The Sony XB950B1 I reviewed was super fun headphone to listen to and comes highly recommended.

Our Verdict on Sony MDR-XB90EX Headphones

If you love bass, you will love the Sony XB950B1. It’s really that simple. There are lots of bass oriented headphones out there, but most of them fail to offer options other than turning the bass boost on and off, and many don’t even do this.

With the XB950B1, you can customize the bass level to your particular needs.

This is a great feature since not all types of music require the same amount of bass. You can have an insane bass level for hip hop or dance music, for example, but turn the bass to a more moderate level when listening to classic rock. If you’re listening to a podcast, on the other hand, you can even turn the bass down to neutral levels.

When you consider how much bass this headphone offers, as well as the additional features such as a built in mic, simulated surround sound, app control for iOS and Android, onboard controls, and voice prompts, it becomes clear how much of a value this headphone really is.

The Sony XB950B1 is a bit on the bulky side and may be too large exercise or for on the go use, at least for some people. Still, if you want a wireless Bluetooth headphone with all the bass you will ever need, you can’t go wrong with the XB950B1.
