Review on 🎧 KZ ZSX 1DD+5BA Hybrid HiFi Stereo In-Ear Monitors: Noise Isolating Sport Earphones with Detachable Cable (MIC, Purple) by Imed Artun

They don't fit well and are difficult to keep in the ear. My much cheaper headphones sound a lot better and have a lot more bass. The highs are very high, but that's all you hear. Buy well-known brands and you will get more honest advertising and better quality. I wasn't expecting good bass from in-ear headphones, but that's not the case and high frequencies can ruin your hearing. It might sound better in a few hundred hours, so I'll let you know. At the same time, you pay a little more, but get a well-known brand.
