Just got mine today. Was browsing amazo, found this little gem and couldn't help myself not to order one. It's a freaking $13, so I thought to myself even if they sound bad, I got nothing to lose anyway, but the reviews say otherwise. So, first listening, I can say this iem sounds good. It does so many things right.
1. Treble is smooth, yet sparkly and airy.
2. Mid is lush, not thick, but not thin either, very natural.
3. Bass is tight and punchy. It doesn't cover up other frequencies.
4. Build quality is very good. Love the cable and housing.
For only $13, I think everyone should have it.
