Summary: It's time for another review that I've been sitting on for a while. Writing a review of a vintage headphone is difficult at the best of times, and there are some strange features of the AKG K340 that are even more difficult to deal with.
Pros: musical, fun, stunning treble, no fatigue, forgiving
Cons: Requires monster amp, not especially detailed, a bit slow, slightly muddy bass, each pair is a bit different.
Conclusion: For a while now our favourite headphones have either been the Etymotic hf2's or the Philips SHE9850 as both deliver a brilliant sound quality and fit. Unfortunately for AKG, the K 340 earphones don't come up to scratch and therefore we can't recommend them over those two sets.
Pros: Volume slider, if you can get a good fit they sound great
Cons: Loose in the ear, hard to tell the R and L sides apart, lots of sound leakage
