The sound quality is excellent! They fit comfortably in the ears. They block out outside noise effectively, making them suitable for walking on the street. They have a lot of bass, with the mids being reasonable and the treble sounding great! They are a very good value for the price. Compared to the Xiaomi Hybrid Pro, the ZSN has a more pronounced bass, fewer mids, and almost the same treble. The bass is perfect for use on the street, but it might be excessive or annoying when used at home in a quiet environment.

The seller is good, and the product is good. The headphones are exactly as described, have good sound, are well-made, and look nice; for the price, it's hard to ask for more. It took a month for them to arrive, but the package could be tracked the whole time. I'm very happy with this purchase, thanks.

The product is excellent and as described, though the delivery was slightly delayed. The quality is good considering the price.

The product is authentic and of high quality. It includes four additional pairs of earbud tips, which fit the ears perfectly, as the complimentary gift promised. Delivery was sooner than expected. I am very satisfied.
