Product Details

This is the Fosi Audio GR70 vacuum tube headphone amplifier.
I bought it because I wanted to try the sound of a tube amplifier, but it didn't suit my preferences.
Usage time: 2 hours
The main unit has no scratches or dirt.
As it is shipped from overseas, the outer box had dents and crushing upon arrival.
All accessories are included.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
