Wired Piyohon 4 by Hi-Unit, comes with a carrying case for convenient portability. There is a volume discrepancy, with the left side sounding quieter, which feels off. I purchased this on Mercari, and after contacting the official support, the warranty was not applicable, so I haven't had it repaired. Therefore, I am selling it as a junk item. No returns or refunds, please. - Brand: Hi-Unit - Accessories: Carrying case - Cable Type: Wired - Earphone Type: In-ear - Other: With clip Thank you for viewing.
