Fiio M11 Plus LTD ss + Samsung 512GB

I purchased this item new from e-earphone.I used it regularly for about two years after purchase, but I haven't had much opportunity to use it since then, and it has been stored for a long time.While there may be some minor scratches on the main unit, I believe it is generally in relatively good condition. A glass film is applied to the screen and back, but as you can see in the photos, the glass film has some scratches.I believe there are no particular problems with the sound quality or operation. I mainly used it with a 4.4mm balanced connection, so I am unsure about the usage with a 3.5mm unbalanced connection and a 2.5mm balanced connection.Regarding the battery condition, there may be some deterioration due to it being a used item, but when streaming lossless audio on Apple Music while connected to Wi-Fi, the battery decreased by 1% in about 4 minutes. Although it's a simple calculation, it suggests that you could use it for about 6.6 hours from 100% to 0% (※Please understand that this is a reference value as it may vary depending on the usage environment).I don't think the battery drains extremely quickly, but please be aware of this if you plan to play music continuously for a long time.In addition, I will include a Samsung EVO Plus 512GB MicroSD memory card (2024 model) + SD adapter and a dedicated silicone case. faultless for everyday use. superior materials and excellent craftsmanship ensure long-lasting durability.
