10mm Beryllium Diaphragm Driver

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.

Detachable 5N OCC Silver-plated Cable

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

my fav iem 2021

Thumbs up to JQ 👍 for this excellent IEM: buttery smooth tuning, gorgeous looks and ultralight comfy fit.
Excellent fast punchy bass. Addicting sound signature I want to listen with these for hours and hours....and I do.
I guess I'll order a 2nd pair in case they are no longer available.

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!

Could be good?

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!
