It's been several months since I bought MDR-1 RBT. Then, It's now getting too warm to wear headphones. So I bought another device to listen to music and English teaching materials; what I bought was, this time, an earphone, JayBird BlueBuds X, which is able to connect to iPhone via Bluetooth.
I hate large receivers which existing devices of this kind have. On the other hand, JayBird BlueBuds X has minimum things that earphones are supporsed to have to complete the functions.
What I like the best about it is that the earphone can be charged via USB cable and the way looks cool as below:
Honestly, I don't like its package design. It resembles ones of Android or something in terms of color, yellow-green. They're just awful. However, I can avoid the color since they also offer a color set, without the color, which consists of white and black.
Bluetooth headphones/earphones are looked like their sounds are comparatively worse than cabled ones. I can't feel it's so bad so far. Basically, I don't mind the quality of sound if only it's not too terrible, so you should doubt of what I'm saying.
