the 1more is quite a bit more v shaped than the A4, with teh configurations I have tried thus far. The 1more treble is more energetic and relatively more forward and overall A4 is more balanced compared to the 1more. The A4 won't wow you out of the box since it doesn't have the shimmer or sizzle of the 1more triple driver.
Overall clarity and resolution sounds better on the A4 to my ears, the A4 is quite comfortable, its pop in and go. With the 1more, due to its thick and angled nozzle isn't as easy to pop in and get a good seal every time. I should mention that the 1more treble makes it harder to listen to at higher volumes vs the A4.
Remember, this is all relative of course. Does that mean the 1more triple driver is bad? Heck no, I love mine to bits! Its a lovely piece of kit, but the LZ A4 is a more mature and refined iem with a lot more flexibility.
