When you think of Audio-Technica headphones, the first thing that comes to mind probably isn't an in-ear sports model. Rather, the company is much better known for its full-size over-the-ear models, including the popular
So it comes as a little bit of a surprise that in the waterproof ATH-CKP500 SonicSport earphones, Audio-Technica has made very good-sounding -- and well-fitting -- in-ear headphones that are sporty but also work just fine as a day-to-day pair. I wish there were an in-line remote with a microphone for cell phone calls, but otherwise I didn't find too much not to like about the ATH-CKP500s.
Design and features
While they have an all-plastic design, the ATH-CKP500 earphones -- available in black, red, white, and blue -- seem sturdily built and are certified as IPX5 waterproof headphones. That means they can withstand a good dousing with a sustained "low-pressure" spray, but can't hang out underwater too long (so, no, you can't wear them swimming). That said, you can rinse them clean, and they're certainly sweat-resistant.
What I liked about them was the fit. As with some competing sports models, you get a few different sets of "wings" (Audio-Technica refers to them as C-shaped eartips) that are designed to "nestle" inside the inner rim of your ear and create a secure fit. Monster's sports earphones have a similar design but I found the ATH-CKP500 earphones slightly more comfortable.
Along with the typical silicone eartips, you also get three sets of ridged eartips that allow some sound to filter in from the outside world. This can be important for runners and bikers who want to be able to hear oncoming traffic. Without a tight seal, you do lose a little bass, but that's something some people can live with in exchange for a bit of extra safety.
The cord has a couple of design traits worth highlighting. For starters, the cable running to the right earpiece is longer than the one running to the left earpiece. This is called an "asymmetrical" cable and the reason for it is so that you can wear the longer section around behind your neck.
Secondly, the base cord is relatively short and is designed for use with armbands. A 2-foot extension cable is included to add more length if you keep your device in a pants pocket or clipped onto your belt.
