Look what just arrive!
TENNMAK PRO DUAL DRIVERS:


(All my Dual Drivers earphones: tennmak Pro, VJJB V1S, KZ ZN1 and Brainwavz R3)
Out of the box they REALLY IMPRESSE ME by their clarity and instruments separation, bass is quite big and punchy too, soundstage over average, construction is excellent and they are the most comfortable of all Dual I have, like they were mold for my ears, first time I put these in I got the perfect seal (use good tick silicone tips).
Will give more impressions. Now I listen to them with my Ibasso DX90 wich make the sound razor sharp detailed and bass more punchy than vast...with the DX80 bass was perhaps too much so will give them more listen and come back!
I buy it there for an absurb 22$:
