SHOKZ bone conduction headphones with an open-ear design and volume control buttons. - Brand: SHOKZ - Model: Bone Conduction Headphones - Features: Open-ear design, includes a dedicated pouch - Operation Buttons: Volume control buttons available - Certifications: CE, UKCA Thank you for viewing. I purchased these for approximately 10,000 yen around May of this year. I haven't used them much since I bought them, so I decided to list them for sale as I thought it would be a waste to keep them. Thank you for your consideration.
