So I am not a big fan of IEMs and I want something simple to carry around and earbuds are becoming rare and rare. So Yuin PK1 are widely regarded as one of the best earbuds in market closely followed by Blox RE3. I didn't get PK1 since they are 100$ range and I don't have amps to power them. I got the next best thing that is Yuin PK3. First impression: They are very clear and don't hiss or any other extra noise. High Fidelity. They are not too loud, so they don't always bring the boost. They have flat audio signature, so bass drums don't pack the punch which was more prominent in my AKG earphones. Mids are very clear. Vocals sound amazing. I am more or less happy. It is tricky to choose between actual bass and slightly boosted bass.
