  • Overview

    The ATH-SPORT50BT wireless in-ear headphones pair great sound with great fit and freedom of movement to fuel your workout wherever it takes you. The comfortable ear-hook design keeps the headphones securely in place so the powerful 9 mm drivers can deliver all the crystal-clear audio received through the Bluetooth wireless signal. And with a mic and controls conveniently built into the left housing, it’s easy to handle calls and control your music on the run.

    The fit and sound characteristics can be adjusted further through the interchange of two types of included eartips: standard silicone eartips (XS/S/M/L) that provide outstanding sound isolation and ridged eartips (S/M/L) that allow some ambient noise to seep in for safer use outdoors. The internal lithium polymer rechargeable battery delivers six hours of continuous use and recharges easily with the included 30 cm (1') USB charging cable. The headphones are also IPX5 Waterproof Certified*, so you can wash them off when your workout is through.

    Available in black (ATH-SPORT50BTBK), blue (ATH-SPORT50BTBL), pink (ATH-SPORT50BTPK) and yellow (ATH-SPORT50BTYL).

    *IEC rating “IPX5” (“Washable”). The headphone may be washed using running water (not completely waterproof).

    Not really sport worthy


    I have been using these for about a year now and even though the sound quality is great they keep falling out of my ear. Pretty annoying when you are running.

    Really good product


    Awesome product. Only problem is that there is a quiet hissing when I have the music very very low, not sure if this is supposed to happen or if there is just a slight error with mine.

  • Q & A

    Do these use the same drivers and EQ has the SPORT70BT?


    No, the tuning and sound signature of the two are different.


    Can these still be used while they are recharging?


    Thank you for your inquiry. This site is designed to answer questions for the Americas. Please see the below link to find the Audio-Technica office responsible for your part of the globe. They will be happy to help.


    I can choose the style from the drop-down menu, but there's no option to purchase the headphones.


    The ATH-SPROT50BT are now available for purchase via the website.


    I got a pair of these headphones as a birthday gift, however; they keep falling and just not fitting. I don't have the receipt or the payment information, but I want to know if I can exchange them for something else.


    As the manufacturer, we do not sell direct and any exchanges, returns, etc would have to go through your dealer. If you purchased through the Audio-Technica website, you may contact the company that handles the online orders here:


    When will these be available?


    Thank you for your inquiry. They are available now.
