Review on KZ ZSN Pro X Earbuds Earphones Yinyoo - Hybrid Dynamic Driver Balanced Armature Headphones, Dual Driver 1DD 1BA, Deep Bass Stereo Sound, Ergonomic & Comfortable (with mic, Black) by Steve Cooper

These are "KZ ZSN Pro X” in-ear headphones. These buds exceeded my expectations. What I like best is that the frequency response is very balanced, there is nothing boosted or dampened. The highs are crisp and clear, the lows are smooth as silk with just enough "rumble" to keep everything reasonable. I listen to Hi-Res Classic 24bit 96kHz and hear everything that can be heard. Nothing collides, every detail that is in the recording is reproduced by these headphones. I use these earbuds with the LG V60 phone, which is by far the best phone for audiophiles, and these earbuds make it even more obvious. So if you're looking for in-ear headphones that you can use with any high-end portable audio player, consider these headphones. Since the cord is detachable on phones, it is available with or without a built-in microphone. I accidentally bought the microphone version. The microphone option is fairly cheap, so the microphone is the bare minimum for phone calls. It doesn't even offer vol+ vol- buttons. The cable itself is an ornament and looks classy, which matches the characteristics of the headphones. Another advantage of the KZ ZSN family is that you can also order a replacement Bluetooth cable. This turns wired headphones into networked wireless ones. The BT cable has an LDAC and AptX HD codec, this is not a replacement for the cable, but there is an option and it is a high quality one. I am attaching a photo (but to be clear this needs to be purchased separately). Back to the earbuds: they are shaped to fit and practically disappear in the ear. The included 3 sizes of rubber ear tips are pretty standard but when installed properly they offer good outside noise blocking but you can still hear small noises around you when not playing. The cable has a rigid over-ear loop that keeps the earbuds in place even during physical activity. I replaced the included ear tips with the T500 memory foam as it's more comfortable in my ears and blocks out outside noise a bit better. By the way, these are not noise canceling earphones. Active noise cancellation is probably not what you need if you still want to hear every detail available in whatever piece of music you're listening to. Overall I am very happy with the headphones, they exceeded my expectations, I don't know why they are priced under 25€, in my opinion they can compete with almost anything. I can't find any cons other than the fact that memory foam tips should have been instead of the usual rubber tips.
