  • Overview

    Don’t sacrifice great sound when you hit the gym. Audio-Technica’s ATH-CKP500 active-fit in-ear headphones feature ergonomic C-shaped eartips that nestle naturally in the outer ear to hold the headphones securely in place. Their angled housings direct the cord behind the wearer’s neck so it stays out of the way. In addition to standard sound isolating eartips, the ATH-CKP500 comes with newly designed ridged eartips that allow the user to hear ambient noise like traffic or other runners for safer use outdoors. The headphones have IPX5 Waterproof Certification* that allows them to be washed after use. They are available in black, red, white and blue, and come with a cord clip and 2-ft. (0.6 m) extension cord.

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

    Nice ear buds that lock inside the ear for retention


    Most active earbuds have designs which use the outside of the ear for retention, which can be uncomfortable for long-term wear-- especially when wearing glasses or sunglasses. These have a unique silicone cushion that secures the bud into the ear by locking into the natural contours of the outer ear. Sound quality is reference-perfect to my ears; neither too much treble nor too much bass-- nice, neutral, flat. The two-piece quick-disconnect cord is a great feature as well. The *only* criticism I have for these is that the outer jacket of the cable transmits a bit of vibration into the ear whenever it rubs against clothing. All earbud sets do this to some degree, but for these it seems a bit more pronounced. Since buying my first set I have purchased several more both as spares and for family and friends who are looking for a quality set of sports earbuds.

  • Q & A

    How do I wash the headphones?


    You may wipe down your headphones with a damp cloth. There are also third party cleaners you may use.


    does it come with volume control ?


    No, there is no inline volume control.


    Ok so im looking for something new but cheap kinda just for music because my old ath-m50's (not m50x) broke. How well do these compare to my old ones


    The ATH-M50x headphones are no different than the original ATH-M50 headphones except for the addition of a detachable cable.


    I took off the silicone tip so I could put a new one on, and now I can't fit any of the tips on. The opening is way too too small. Is there some trick to putting the tips on the earbud that I am missing?


    You may view a helpful video here:


    Do you offer a shorter extension cord? Something 6" to 1' shorter? Your product team clearly designed the CKP500 for either arm band users or people who put their device in their pocket, but it doesn't work well for people who carry their device on their hip.


    You may use any third party 3.5mm extension cable to connect the standard 3.5mm connection from the headphones to your source.


    Where can I buy replacement tips? The curved part of one of the ear buds is starting to tear and I would like to replace it before it rips completely.


    Please contact our Parts Department at (330) 686-2600 ext 5002 or at for assistance with this.


    Length of cord to earbuds not equal?? I bought a pair of ATH-CKP500RD and the right ear bud cord is a foot longer than the left ear bud cord and it puts disproportionate weight on my left ear. Is that a flaw or how they are made? Thanks.


    The longer one is designed to go around the back of your neck to your right ear.


    The cable lengths were designed to be different.


    can this be used with mp3 player?


    Thank your for your inquiry. As long as you MP3 player has a 3.5 mm headphone jack they should work.


    Lost ear tip Is there any way to buy a replacement ear tip? I lost one of my medium "active-fit" tips.


    Any ear tips for Audio-Technica in-ear buds can be purchased through the Audio-Technica Parts Department ( Thanks!


    Since these headphones are c shaped contoured for maximum comfort and stability will these fit all ears comfortably especially teens IAM a teen needing good headphones do you recommend these


    This can be a difficult question to answer, because every one has different sized ears. These headphones are designed to ergonomically fit in most adult-sized ears. If you believe your ears are of comparable size, then these earbuds should work for you! Thanks!
