Recently I bought a new sport earphone from Audio Technica – ATH-Sport3. Here’s my experience of this amazing sports earphone.

Design – Cool design, light weight & very comfortable

Besides the cool red design, Sport 3 is has water resistant feature. The cable that connects to the housing (You can refer to the diagram for the name of the parts) is covered by a flexible plastic tube. You can bend it according to your ear shape too, very handy. It comes with additional earpieces that you can replace according to your ear shape. There are two types of earpiece. The standard one is the default earpiece that you see, another type is the active earpiece. When you use the active earpiece, external environmental sound can be easily heard. If you are running on the road, this will be very helpful.

Sport 3 is very light and comfortable. When I wear it, if it’s not because of the cable, I can hardly feel it. It fits nicely in my ear. There’s a cord slider for me to adjust the length of the cord behind my neck. Sometimes it’s quite frustrating if the cord is too long. When you are running, you feel something keep tapping your neck. Sport 3 solves this problem.

Sound – Awesome sound quality

I’m very impressed by the sound quality of Sport 3. I didn’t expect it to be so great. All the previous earpiece that I owned has a common issue – I can’t really hear the low frequency when I was running. How many of us when wanting to hear the bass better, we need to push the earpiece further to our ear? I did that many times. But with Sport 3, I don’t have this problem. The bass was strong enough but not overpowered. The high frequency response was great too, up to 25,000Hz. Usually majority are only projecting up to 20,000Hz only. The overall sound is balanced and open. Stereo image is clear. I feel like the performance is right in front of me.

Only thing that took me a while to get used to it was learning how to put on the earpiece. Apart from this, everything is great! Highly recommended.
