This is the beyerdynamic LAGOON ANC JP TRAVELLER (Black). [About beyerdynamic] While it may not be a familiar brand in Japan, their headphones are used in music production environments overseas, and can be seen in recording videos, etc. *This is about the manufacturer, not this specific product. [About the Product] Supports Bluetooth and wired connections. Noise cancellation can be set to OFF, 1, or 2 levels. Announces battery level on startup (surprisingly convenient). Sound quality can be adjusted via app integration. Volume and track control can be operated by touching the logo on the earcups. MOSAYC (sound personalization technology) is available. [Condition of the Product] The ear pads have deteriorated and have been replaced with non-genuine pads. The head cushion also has cracks. There are no other noticeable scratches. The operation is fine, and the battery is also fine. The only included item is the headphones themselves, but they can be charged with your own USB-C cable. Please purchase if you understand the condition of the product.
