As we know, adopting Beryllium driver minimizes the audible ringing and distortion heard from traditional metal diaphragms (e.g., titanium or aluminum). Beryllium enables an extra octave of useable, non-resonant high-frequency energy-pushing breakup modes beyond the audible band. JQ 4U has made advantage of this type of driver to present you a shockingly satisfactory sound effect.
Cable is the least to be overlooked components in a HiFi earphones set. Thus we have chosen the high quality 5N OCC silver-plated cable along with the braiding technique. The cable can great reduce the distortion and improve transition. Detachable feature provides future upgradeability. You can either change the cable with a new one or just replace with a preferred cable. The choice is yours
Handmade isn’t only about technique but also our attitude and aesthetics towards handmade earphones. Each pair of JQ 4U is carefully crafted by our artist with unique pattern. Designed with two colors, you have more choices. Built with German imported Egger resin, the shell is durable and stable as well
Based on large data of human ears, JQ 4U is built with a special shape to fit your ear securely and also comfortable. It can also greatly decrease the noise. With it, you can enjoy longtime, no disturbance music, anytime anywhere.

I finally bought these from Linsoul on Amazon and I must say, they’re pretty good. I do think I payed a little too much, but worth it. The only thing I did was put on another cable for more bass. A copper cable really helps. I also used final “e”eartips. I would put these up against my KBear believes! Don’t expect a ton of bass, but they have enough. A little burnin helps. I would like to see more YouTube reviews on these to let people know. Good purchase, recommended!
I would like to buy these, but I’m afraid they might sound too much like the Fiio FD-1s or the Jade Audio EA-1s which I already have. I like single DD drivers and this one looks good. If it goes on sale, I might buy it. Keeping an eye on it. Only review on it is from BGGAR on YouTube!
