Quick review :
I got this around 2 days ago and have been listening to it with my ath ew9. So far I'm loving it!
the sound quality is so much better than my phone, which is great because I got it so I could avoid using the phone for music. My ew9 are bright (or sharp? Sorry I don't know which term to use ^^;; ) so the "s" sound pierces my ears (very noticeable when listening to the 3rd track of Galileo Galilee's See More Glass album feat Aimer) but on the x3 it's so much better: not that piercing, sounds rounder (not that sharp). As for female vocals, there's just something "different" but I just can't put my finger on it.
From what I've listened to, it seems like this player prefers more relaxed music such as Halsey, Daft Punk (Random access memories), Angel Snow, Joshua Radin. More powerful music like Fall Out Boy (American Beauty album) and Nickelback (no fixed address album) sound veiled, like there's a padding or something;it lacks that punch and oomph. I think that's because of my earphones. I'll have to try the x3 with my k550 when I return home after vacation.
UI is very basic, reminds me of my old OPPO mp3 player with 256mb memory iirc, very nostalgic
What bugs me though is how you have to press so many buttons just to go to the now playing screen. For example, I like to browse different folders while listening so I can change albums or songs, but if I want to pause the current song, I need to keep pressing back until I reach the home screen,then I need to press a few buttons to get to now playing. It would be better if I could get to the home screen/now playing screen by holding the back button for a few seconds. This would be a great feature especially for people with lots of folders.
That's pretty much it. Overall, amazing device considering its low price. I'll have to try pairing it with my other gear to see what goes best with it
Thanks and happy new year!
Update: Carly Rae Jepsen 's I really like you and breaking Benjamin sound great! I guess the recording of fall out boy and nickelback were bad...
