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

Good headset, hard to find B pin bluetooth module. 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 and gets incredibly annoying. Sound quality depends on your earbud, but only about half the time. The buttons are awfully tiny, it's a shame I've never pressed buttons that small before, it's ridiculous.
