JDSLabs CmoyBB Headphone Amplifier



JDS Labs’s success is due to cMoyBB’s legendary bass boost switch. Switched off, your original audio signal is amplified. Switched on, bass increases up to 9.4 dB for a perceived 2x increase in bass volume.


Older cMoys use thin wires or protoboard to transfer audio signals. cMoyBB uses a carefully designed PCB with attention to detail that cannot be achieved in protoboard amplifiers, or even in circuit boards designed by experienced hobbyists.


cMoyBB handles more than twice the voltage of most cMoys and supports dual rail splitters. The result is over 200% higher power handling than the original cMoy! Decoupling capacitors on all power pins significantly enhance opamp stability and sound quality.


cMoyBB’s power input jack allows you to power the amp from your desk. Optional charging support also provides convenient, integrated 9V NiMH battery charging.


cMoyBB is cased inside of a brand new Altoids ® Peppermint tin, protecting the circuit from some forms of external EMI / RF interference. You may choose between two tin styles: Peppermint or Wintergreen.


Specify your headphones during checkout and we’ll optimize gain, bass boost, and output power for best performance with your headphones. A technical summary ships with each custom cMoyBB.

    Ni salah satu prodak yg gw beli dari headfonia setelah sy minta review dari tmn2 yg make plus ntn video review youtube headfonia dr mike berulang-ulang ampe kuota kandas and akhirnya sy devide ambil dan lnsg versi MOB

    Cmoyy ni bener-bener Amazing dengan pricing segitu, dengan cmoyy ni suara file lossless dari ipod classic menjadi lebih tebel, bersih dan lively. Plus ni jg bener-bener boost bass menjadi bulet sehingga suara terkesan ga terlalu sopan tapi elegan he2

    Overall, great to hav this stuff and can’t wait to pair it with my MSR7NC dr Headfonia juga yg blm sempet gw tandemkan karena lagi charging pas gw type review ini dan jg Co-Donguri yg lg PO
