Just got this message from Nicehck...
Old friends,
This is our new 7 driver units earphone, NICEHCK NX7, 4BA+2DD(Dual Carbon Nanotube Dynamic Driver)+Piezoelectric Ceramics Driver, hybrid 7 Units.
/:011Now, NX7 is $65 no mic version(with mic $66) , for our old friends ❤
A senior head-fi audiophile friend told me: NX7 is the best sound quality within US $100 ^_^ /:006
I think you 100% will fall in love with NX7.
Sound signature of NX7:
Overall balanced sound.
High resolution, Clear sound profile, Bright and transparent timbre.
Soft intermediate frequency sound with clear vocal. Nice low frequency sound of great sense and with quick transient reaction.
Extraordinary high frequency extension makes the extremely high frequency fabulous and adds more sound details.
This is the link of NX7, buy it from here, i will change the price for you, thanks /:014
