Pros: price, durability, tangle free cord, isolation, loudness, bass, details, large driver.
Cons: sounds muddy before proper burn-in. also, doesn't sound as good if worn normally.
here's a weird thing about them: these sounds punchy and more enjoyable if worn around the ear (worn somehow like se215), if worn normally, these sound little bit muddy and mainstream, unrefined and lacks punch. i don't know why, but it's true (might not work for you, don't blame me). wearing them around the ear is a bit tricky though!
Sound: After burn-in (and worn around ear), the soundstage is large, bass extended well and punchy. Good quality recording sound surprisingly good. Hard to believe, these sounded so muddy and dead after unboxing. These got exceptionally better with burning in and wearing around ear.
these have smooth treble without annoying peaks. The midrange is smooth. Bass doesn't veil anything. The bass extends low, has huge impact and punch. surprisingly, these don't need equalisation when listening to pc (foobar). very slight equalisation when using neutron music player.
These are reviews after wearing them around ear.
These isolates very well too and quite durable.
compared to my previously owned ex300 (these sounded very good, trust me), cx300-ii, ex85 or any iems had before, these are clear winner.
These are quite cheap you should give them a try if you're looking for big sound at small price.
