Review on KZ ZAS Wired In-Ear Headphones, Hybrid 16-Unit High-Frequency 7BA+10mm Dual DD HiFi Stereo Sound Earphones, Noise Cancelling Earbuds (Black, No Mic) by Jermaine Krishnamoorthy

I use KZ in-ear headphones when I'm on stage with my Shure in-ear monitor system. I lost one of my old ones to an outside install (it broke the cable and never found it) so I ordered this as a newer/updated version. I have small ear canals and just couldn't get any of the tips provided to work for me. The sound was sub-optimal with the wrong fit (very limited bass). After ordering the Comply earbuds (you want size 500 btw) I was able to get a good seal and the sound improved significantly. They give a "big" sound, maybe not if you want big bass, but they're pretty darn good and very clear.
