The bass of ATH-WS99BT wireless headphones is said to be over the top. It’s sad to say though that the product didn’t exceed or even reach the expectations for some other features. There is a fascinating detail in its sound. It’s transparent and the sound quality is good. You can clearly hear the separation of the sound of the different instruments. It has an excellent frequency and dynamics.

You can perfectly hear the mids, the small mids’ accent is there, but it doesn’t sound muddy. The highs are as clear as they can get, though they don’t sound as crispy as they could be. These headphones are one of the few wireless headphones that sound good whether you go wired or wireless.

Design and Build

The design of ATH-WS99BT wireless headphones is not the best when it comes to comfort and practicality. They only have a few buttons, which sit close to each other. You would have to look at the buttons when you are pressing them since you can’t quickly identify which is which.

The package for these wireless headphones comes with a USB cable, carrying bag, microphone, and an audio track. The headphones’ headband is adjustable, and the memory foam seems right, though it is a bit thin.

These wireless headphones are made up of good resistant plastic which makes them durable.

They have combined it with albeit leatherette. It feels that these wireless headphones would last long, as long as you would take good care of them.

The memory foam is quite good, but it is slight, and thin, which makes it feel like as if they are not there at all. The replacement for them is available, but you would have to purchase them separately. The headphones’ headband is well padded, though, making them feel comfortable on top of your head. They are also adjustable so that they can fit any head size. These wireless headphones are quite comfortable. It would be ideal if they would change the thickness of the ear pads.

Call Quality and Noise Isolation/Cancellation

These wireless headphones are meant to listen to good music but they are not ideal for making or accepting phone calls. The quality of calls when using these wireless headphones is good. The noise isolation in them is also good quality. When you turn up the volume, you’d be sure that you’d be turning heads since they don’t isolate the sound coming from your headphones.


Upon using these wireless headphones, comparing it with other wireless headphones, I can say that these wireless headphones would be one of the best when it comes to bass sounds. They give rich mids and highs, letting you appreciate the experience when you are listening to music. And the lightweight construction makes it easy to carry around.
