Snowsky Echo Mini

Hey guys! Im looking to buy an mp3 player for school as were not allowed to use our phones even on recess. I have been looking at many players but one really caught my eye, the snowsky echo mini. And i just wanted to ask, is it a good player for the price? The cheapest i can get it for is about 90 usd. I've heard aliexpress is good but the official FiiO site doesn't have it listed on there and i dont fancy buying from a random seller. And then im wondering if a pair of Bluetooth headphones i have right now are fine? (Soundcore Liberty 4 NC) And also if I can transfer music files from my Android phone to the player with a USB c cable? That's all. Thanks in advance.
