The yellow in-ear type is my favourite. It’s so light you feel no stress wearing it, and with nine hours of playback time, even for an overnight trip, I don’t have to worry about the battery. While I’m traveling, I sometimes use the red ear-clip type to match my outfit and bag.
When I’m doing the warm-up stretch, it doesn’t fall off, even when I roll around or twist my body. It feels really light, and there is no stress, however I move.
The day after a match, I often go for a 20 to 30 minute jog. Since I can hear the sound around me, I feel safe while running with the earphones on. They stay put even when I’m sweating, and the cables don’t get in the way, so I almost forget I’m wearing them. It’s really convenient that you don’t have to worry about the battery running out, even on long runs! I like the way you can wear it around your neck using the clip-on magnets.
I sweat a lot, so by the time I finish training, I have sweat running down to my ears. So this washable AE is really great! It’s become my training pal.
