Review on CCA CA4 IEM Earphones: HiFi Stereo Bass DJ Monitor with Noise Isolation, Removable 2pins Connector, and Mic - Black by Tony Ledbetter

Got the CC4 headphones today and started using them straight away. The product is nicely packaged but there were no different rubber ear canal plugs in the kit. I'm eclectic when it comes to music, so I've listened to dance, pop, R&B, early music, classical, etc. For the price these headphones are excellent, the bass is a bit punchy at high volumes but that's to be expected with a tiny driver. I work as a DJ and these headphones come in handy with passive noise canceling. I will try the big brother ca10 and report. I think for everyday use these headphones are fine, but if you're performing or need to hear all the instruments then invest in something better.
