So after listening to the Andros, S8, Fh7 and T800. I can conclude while the T800 is bright, it's actually a warmer sounding iem compared to the rest. The Fiio FH7, Moondrop S8 and Andros all sound very different to each other. All have strengths and differences. 100% the T800 is the warmest out of all of them. When you keep swapping one by one, to my ears it sounds like the Andro is the clearest out of the 4, the FH7 is the most balanced, S8 is the one with most treble energy, T800 is the most warmest. But the T800 to my ears is the one with the details right at your face. Then come Andros, S8 and FH7. Now they all are seriously clear iems. And all honestly have great low end. FH7 would come first, T800, S8, Andros in terms of tightness. In terms of extension, T800, Andros, FH7 S8. In quantity, T800, Andros, FH7, S8. Mids I also find a big difference. Yes the T800 sound the more in the back but they sound correct. They also have the most timbre and thickness while still having great detail. The FH7 while sounding a bit more forward, feel like if the mids are more back then they should. They feel slightly distant but I do agree, this gives a great sense of depth. But detail ultimately feels the least compared to the other 3. The T800 to my ears I feel have the most detailed mids but in a controlled, laid back way. Very in your face but effortless. Andros bring the detail in a clear, crisp, airy way but sometimes lack some of that thickness than is needed in guitars. But clarity is awesome. The S8 is in between the T800 and Andros but some part in the mid sounds a bit shouty, but this only come rarely to me. Treble, is where it gets interesting. The T800 feels the warmest here as well. But in detail terms, it would be T800, Andros, FH7,S8. Even though the T800 feel the warmest, they still deliver the details without a loss of clarity. The Andros are crystal clear, more analytical, great for listening, but I wouldnt use as a every day iem. For me the Andros can be a bit more fatiguing after a while, but they are tuned very nicely. The FH7 have that extra sparkle, more so than T800 and Andros but it's done so so nicely, maybe it's one of the most cleanest trebles I have heard in an iem. It's energetic but yet very controlled. But I still do hear more detail in the other two. The S8 is a mix of all three, it sounds slightly similar to the T800 but weight in the treble to my ears lack a bit. It's energetic, maybe even more than the rest, but detail I feel is the least out of the rest. They all have a bright signature where clarity, detail and resolution is the focus. But they all do it in different tastes. Soundstage. Width for me goes to T800, Andro, S8, FH7. Height goes FH7, Andro, S8, T800. Imaging. T800,Fh7,Andro,S8. Depth, T800,Andro,FH7,S8. This is with me using the 9038s as source and using cable 171 with all iems. So far if I had to rank them. The T800 and FH7 are my favourtie out of the 4. Then Andro and S8. But damn, they all are great iems and honestly you can't go wrong with any. It may seem that the S8 are my least favourite but nope. I actually really really like them. What they do better than all the rest is being able to give a mixture of all of them and make you feel like you arent missing out. All are great iems
If you want fun, warmth, the most detail. But not the most balanced. T800 is the one to go for.
If you want a bit more balance, a bit more treble energy, high clarity, leaner mids. Andros are your poison. Very great for analytical listening.
If you want balance. Good for all day listening. Detail is the least. Great treble tuning. The FH7 is your pick.
If you want a mix of all them because you can't decide which to go for. The S8 is your pick.
