I bought this when my Sony XBA-N1AP had started to stop working and it totally goes beyond my dying pair for giving many little details which used to hide in my old earphones, yet they both share a very similar sound signature to each other. However, 1MORE Quad Driver steps to a slightly brighter path in terms of sound. Nonetheless, the Quad Driver still sounds great in dark-sounding music such as Doom Metal, Stoner Metal, Stoner Rock and so on.
What surprised me the most is how it can separate each instrument so greatly. In busy-sounding music with a lot of layers like tracks in a self-titled album The Dark Element. For example, The Ghost and the Reaper. The earphones deliver dozens of layers from instruments and synthesis so clearly. You can hear almost everything, if not everything in the track.
A majestic symphonic track like Edge of the Blade also shines in terms of fun-sounding and revealing hundreds of minor details such as a lingering flute from a back left side of the soundstage and a brass from the right side during some parts. Moreover, it can balance the heaviness from practical instruments, a synthesizer, and vocals greatly.
The problem for me is how vocals stay slightly behind in those 2 tracks during choruses with a lot of raging instruments going on, but it's only a minor issue.
How about its low, mid and high ranges?
They all are fine while the mid-range is the greatest one by far. High-range is pleasant and will never ever hurt your ears. Additionally, it can reach the far side of this range while staying relaxingly. The low-range is surprisingly good. Surely, it's not bassy, yet it can bring enough bass to please you without ruining another range. It can be heavy when whatever that you're listening is trying to impress you with the bass aspect, not to mention that you can easily notice this range since your first listening if you choose a right song or a right listening matter for testing. The range also displays its power really well in Doom Metal, Stoner Metal, Stoner Rock etc. which I mentioned them in the first paragraph. In King Goat's Conduit album which is the Progressive Doom Metal record, the bass lies behind, yet easily noticeable. If you're looking for a bassy pair, this one is not for you.
I have another extra thing besides music. A highway scene in Deadpool below is the sequence that reveals the true power of this pair fantastically. Its imaging and separation are so realistic. It's like I'm in the scene myself; it blew me away while I was watching this scene for the first time with Quad Driver. Whether you have the pair or not, you can try watching or listening to this video to test on how your earphones or headphones work in terms of cylindrical degrees, imaging, and separation work.
In conclusion, 1MORE Quad Driver is the definitive and quality v-shaped earphones that can beat some, if not many higher prices pair. Like I said in the beginning, it totally and undoubtedly beats my old Sony XBA-N1AP.
