          i recommend!

          I like the tuning of Uiisii. I bought the DT200s. Since the tooth sound is like a steel tooth, I will give it away. The DT800 is much more natural than the DT200s, and the tri-band connection is more natural. The low frequency is heavy, but the dive is still not deep. The intermediate frequency is naturally smooth. High frequency is an advantage, the resolution of the instrument is quite good, and many kinds of music that can't hear the sand hammer becomes more vivid. The included slow-recovery memory cotton cover can better close the ear canal for better low frequencies.

          Okay, it's not very often than I am impressed by earbuds however, these DT80s Quads are amazing!!!

          Before I gave these DT-800 Quads a try, I tried some TBI Pro i6 3 driver earbuds; I sent them back the same day because my cheap $15 and $30 SONY earbuds blew the TBI Pros away—this just simply should not be! Then, my DT-800s came in and I really liked the sound of them right away! It took a little bit to get used to the Dual Balanced Armature Drivers (1st time listening to these kind of drivers) but after listening to them for a while there was all kinds of upper frequency detail and separation between instruments that I've never heard before in the music that I listen to. And the bass, (OMG!!!) was so much better than the TBI Pros—and the Pro i6s had one huge 10mm driver and two 6mm drivers. In spite of this, there just simply was no comparison; the bass on the DT800s was tight but not overwhelming. Could they use maybe just a little bit more bass, sure but they don't really sound like they are lacking; it's just because the mids and highs are so clear that you don't notice that they still have plenty of bass. They are a very well-balanced sounding earbud—I just really love them!!! So much clarity and detail and if I really want to add more bass I can just simply EQ some in with the ROCK EQ setting on my iPod—but I don't even think I'll do this because they sound so great as-is! Thank you UiiSii for making these really great sounding and very stylish looking earbuds—I am a first time customer and I bought 3 of these on Amazon.

          Excellent store highly recommended.

          Headphones are great! I hope to buy again in this shop!


          Exceeded all my expectations! A wealth of beautifully presented gifts. I am a teacher who teaches piano. The requirements for sound quality are still relatively high. The earliest try this earphone, the sound is bigger than before, and the analysis of high school bass is not bad.

          Recommend Uiisii!

          Product received as fast shipping! Thank you very much! Let me say that wearing the feeling, the earphone itself is moderate in weight, there is no top-heavy feeling, the white earphone is very nice to look at, it is very comfortable after wearing it, there will be no falling off, and the replacement earplugs are also very intimate. In terms of sound effects, the low-frequency and heavy feelings are full, the dive is deep, the vocals are slightly insufficient, the high-frequency is clear and soft, not so harsh, it is quite good, and it is worth the money.
