Thank you for looking.
This is a Cayin RU9, purchased new from e-earphone around August of last year.
I am selling it due to downsizing my equipment and changes in my life circumstances.
Please note that this item is also listed on other flea market sites, and may be sold out.
The total usage time is less than 30 hours, and I don't believe there is significant degradation.
As it was always used with the included case, there are no noticeable scratches or dirt. However, please understand that as this is a personal inspection, there may be minor oversights. Please check the attached photos for details.
If you have any questions or requests for additional photos, please feel free to contact me in the comments.
The Cayin RU9 is an all-in-one portable DAC that features MagSafe and vacuum tubes. In addition to three sound modes, it offers higher output and more powerful sound when powered, and can also be connected via Bluetooth.
Unless there is an urgent matter, I plan to ship it on the same day or the next day after purchase.
Thank you for viewing until the end.

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.
