          Best in-ear headphones I've ever owned

          I bought these to see what they were like because I was so impressed with my UiiSii T8 in-ear headphones. The T8S in-ear headphones cost a bit more but they are absolutely worth it in my opinion because you will hear so much more detail in every track you listen to. Music is just more enjoyable to me when you can hear more of the original recording's details. I can hear things I've never noticed before in my favourite tracks. Things like individual instruments rather than the overall sound of the band, more of the notes being played, the singer taking a breath, what people are cheering in the background on live tracks, where in the soundstage each instrument sits, etc. They are really enjoyable headphones and really worth a try.
          One thing to mention before I end is the bass on the T8S seems less loud but more controlled than on the T8. If you want louder bass, you can of course fiddle with the tone controls and/or equaliser settings on your music player. Like any in-ear headphones you need to get a really good seal with your ear canal. The T8S comes with many silicon tips and it doesn't take long to find the ones that fit you best.
          If you're thinking of upgrading your headphones you should give these a go. I'm really impressed with them.


          Granted I'm no audiophile but as your regular sound noob just needing a pair of headphones to listen to music. So far I've been pretty happy with both the sound quality from the headphones and mic quality when speaking on the phone.


          The earphones work well in my ears, but more because of the shape of the ear and not necessarily have anything to do with the earphone itself.

          Love these

          Absolutely impressed with the sound quality of these, I use my pair 8 hours a day 5 days a week and just keep finding new notes in songs I didn't hear before.


          I've had these for awhile now. They sound great. I want both red and black. I compare it and still think that red is more fashionable. The sound quality is very good, the pattern on the earphones is also very beautiful, the quality is completely ok, I know it is good when I take it in my hand, I also sent a small ear bag, like it.
