Sony WF-SP900 Review

Behold the street-smart Sony WF-SP900 Wireless headphones; a one-of-a-kind Sony installment designed primarily for sporting activities. It is a multipurpose Bluetooth earpiece that has many unique features under its sleeves. But for all it’s worth, the draw point for this product is its distinguishing water-resistant feature that swimmers look forward to more than anything.

The Sony WF-SP900 has also has NFC compatibility, features a 4GB internal storage, and a battery that lasts up to 12 hours. Now, before we give you the spoilers, let us give Sony a resounding accolade for this accomplishment. Sony really gives the Apple AirPods a run for its money with the WF-SP900.

It is indeed interesting how Sony changed the game in such a few short years. During the late 90s and early 2000s, Sony channeled its efforts into the video gaming industry with its flagship product; the PlayStation. Sony was so immersed in the gaming world that it fell short on so many advancements in the audio technology industry at the time.

All that changed, however, since the man behind the Sony Walkman was brought on board to once again put Sony back in its rightful place. Now, with the Sony WF-SP900, the Japanese brand will be continuing on that long tradition. 

Subsequently, this will be a comprehensive review of the Sony WF-SP900. We will highlight its general specifications before discussing its sleek features.

Features of the Sony WF-SP900

Now, let’s dive into the main features proper for the Sony WF-SP900. Before anything, we reiterate here that the Sony WF-SP900 is targeted at sportspersons who enjoy listening to music while on the go. This installment is a successor to the WF-SP700, another Sony masterpiece, but certainly fairs better in many ways. With that said, here are six unique features that give the Sony WF-SP900 its bounce.

  1. The Water-Resistant Feature

With the WF-SP900, Sony attempts to improve on the concept of listening to music underwater. The Sony WF-SP900 earphones are therefore dedicated to sport and swimming. And yes! Sony really went to work on this piece to deliver a set of earbuds that perform optimally underwater.

You may recall that Bluetooth signals can’t really transmit inside water. However, this is where Sony bypasses the rules of physics. You can listen to your music conveniently while swimming if you are listening via the onboard storage. This was a brilliant and well-thought move on the part of Sony.

  • Accessories

What you will find amazing about the Sony WF-SP900 is the way it pays attention to detail. The package comes with a large assortment of accessories to aid portability and comfort. The silicone ear pods are available in four different sizes to fit snugly for any ear size. Even the arc supports are also made in four sizes; the small (S), medium (M), large (L), extra-large (XL).

When it comes to the earbuds, the WF-SP900 also packs an additional set. Swimmers will particularly benefit from its watertight fitting. It is a no-brainer that these too come in four separate sizes! Take a look inside the box some more. These guys also added a round cord to hold items in place, which could come in handy, especially when doing strenuous activity.

You can tell the Sony WF-SP900 is one hell of a bumper package.

  • Battery

The battery is also an interesting feature of the Sony WF-SP900 for a few reasons. First, it provides three full hours of “Bluetooth” listening time. Subsequently, you can get six hours out of the battery if you listen via its in-built memory. If you charge it using the charging case, you can get anywhere from 9 to 15 hours of playtime.

Now, this is where things get interesting. The Sony WF-SP900 battery has a proximity sensor that detects if you have the buds on or not. It is so dead-on accurate that it can tell the ears from any other body part. In that case, when not fit on the ears, the sensor assumes the headphones are not in use and triggers the off switch to conserve power.

  • Controls

Controls are something to talk about on the Sony WF-SP900. This one’s actually kind of tricky, especially if you are not very familiar with this line of Sony headphones. The whole thing works on tap technology. You need to tap the controls to play or pause songs, change tracks, take calls, and increase or lower the volume. It takes some getting used to but can be fun once you fully wrap your heads around it.

  • Storage

The Sony WF-SP900 comes with 4GB storage to carry your music, especially while doing chores around the house. All you have to do is connect the device with your PC to add or remove songs. You would not even require any kind of special software or app to do this. 

  • Sound

Let’s talk about the sound quality of the Sony WF-SP900 a bit. There are a few things to watch out for here. First, the bass isn’t as high as expected. The volume isn’t as ear-busting as its contemporaries in the earbud market. A high-profile headphone of the caliber of the Sony WF-SP900 should have a more impressive sound output. Nonetheless, they didn’t do all that of a bad job. You will still get a decent play using this product.

Pros and Cons of The Sony WF-SP900


  • They did well with proximity sensors to help maintain battery life.
  • The tap features are also very smooth and super-intuitive.
  • You can access the voice assistant on your phone with the WF-SP900.
  • Has a great battery life.


  • Some may find the tap controls not as conducive as anticipated.
  • It has poor ambient filtering.
  • The audio quality isn’t as top-notch.
  • The turbulence movements in water produce unwanted noise.
