These earphones are a great find. The sound across all ranges is crisp and clear. No levels are drowned out and the blend is superb. The bass response is also very good for an earphone, but it isn't overdone as many bass-heavy earphones are these days. The bass here is truer.
My only issue with these earphones that nobody else has seemed to highlight is the leakage. They do seem to leak moderately. They are not in the same league as Apple earphones, for example, which are the bane of the commuter's existence. But the leakage is noticeable, to the point where you feel self-conscious listening to music at the volumes you would like to in quiet places, like a train for example. As mentioned, the leakage isn't too severe and don't let it put you off these great earphones, just be aware.
So only 4 stars for now and I look forward to the next edition of these generously priced earphones where they sort the leakage issue out.
