L2 has slight midbass and subbass boost, but it is tight enough not to bother me. The uppermids and upperhighs are also a bit emphasized, but extremely non fatiguing (I'm very sensitive to treble)
And the treble sounds realistic enough for the price point, the whole sound doesn't sound artificial to me at all.
Although I have to say that the Ostry KC06a with KZ WHIRLWIND tips has more clarity, while being as smooth. But that is the only thing they're better at. They broke today, and I've switched back the Philips L2, and L2 basically does everything better except clarity.
BUT they're nicely clear own their own, it's just that the KC06a with the WHIRLWIND tips are exceptionally clear, especially for that price.
