Pros: Guitar strings, Heart-wrenching highs, Great Bass extension, Detail
Cons: Comfort, Dependent on ear-canal size, Price if purchased new
Absolute steal at this price.
Should have given a review on these a long time ago but unnecessary because for one simple fact.
You either get a good fit on these and experience pure nirvana or dislike it for any possible conceived ideas.
It's quite inaccurate to listen to people's opinions as well.
Some people clearly state that the IE8 is much better than the Tf-10 but the Se530 is inferior. Others state the Tf-10 is worse than the ck-10s. There are even people that claim the tf-10 lack bass and the highs are sibilant. This all depends on many confounding factors.
But regardless to say, imo, I couldn't be happier with these.
