🎧 KZ PLUS Waterproof Aptx Bluetooth In-Ear Headphones with Mic - Replacement Cables for KZ ZST ES3 ES4 ZSR ZS10 AS10 Review

The audio is fine until you decide to use it for hands-free calls. Audio output from the speakers and microphone-in is of unacceptably poor quality. I hope it's just because it's the Bluetooth 4.0 version. Someone mentioned that connector B fits all headphones KZ makes. The reader is warned - this is simply not true. There are ports A, B, and C, and each is different enough to make a difference.

This one works well with my CCA headphones but has some issues, the left ear has some very bad feedback issues, music playback is fine but with everything else it's terrible, there's significant audio delay and the left ear randomly gives in and out no longer plays bass, this is fixed by turning bluetooth off and on again, but after a while it becomes a problem. The audio is delayed by about 4/10 seconds and the buzzing sometimes doesn't stop…

I only use them at the gym when the cords get in the way. I only use them for three or hours before charging so I'm not sure how long they will last on a single charge. I use KZ ZSR (three drivers) which are always included. The KZ headphones are well priced, but constantly changing cables is not a good idea. Connectors are not made for abuse. I usually use a dedicated DAP with wired headphones, so I wasn't expecting very good sound from Bluetooth and phone. The sound clarity and overall…
