EF500 (open-box)

Everything was fine, the EF500 sounds perfect! Great discount! thank you

Very good sound and value. Absolutely recommended.

Excellent for the price and a great pairing with the HE1000 stealth.

great sound, but device is a little noisy, overall very good

I have the entire EF series equipped with the R2R Himalaya, and this is definitely the best value for money (open box). For the price of a dongle, you get a top-notch all-in-one that can also be used as a pure DAC (which is what I use it for).
