Summary: These will make you lose hf sensitivity, if you haven't already. Nice bass and mids,but intolerable highs with sharp, sibilant sounding peaks:
No, they really will not improve with burn-in. Really. Especially wrt sibilance.
Pretty comfortable (tips/fit), but otherwise practically fall apart in months and sony only gives 90d ltd warranty and flatly refuses to replace afterwards.
Pros: Nice fit, good mids, if you are hf deaf. Great mids/highs details
Cons: Sibilant highs,uncomfortable y-split, back plate on L fell off in 1/2 year, cable expanded and became slimy, plug and earpieces enamel peels off in 3m
Summary: Excellent headphones. I bought them a year ago and I was truly amazed by it's quality. But now the sound in the right ear plug is starting to be glitchy due to a fault in the wiring even though I've always carried my earphones in the case they came with. i probably won't buy them because they are to expensive and don't last very long.
Summary: I bought these headphones for running with, as my previous sennheisers cables had (once again) snapped inside. Like the look, thought they seemed different. The sound quality is good- though it does lack bass. I am not an expert- just like a good rich sound, which these did not quite reach the standard of the aforementioned sennheisers. However, and the main reason I give a 3, they are VERY noisy when running- regarding the wind.
Summary: ich brauchte einen in-ear- Kopfhörer, der sich von den durchschnittlichen Kopfhörern unterschied, leider sind so viele Plagiate unterwegs und man kann sie leider vom Aussehen kaum vom Original unterscheiden.Also Hände weg und nur vom deutschen eingetragenen Händler kaufen. Kostet dann auf jeden Fall über 200.-Euro.
