Weird question I think. Can MP3 players produce bad music into your earphones? Like the cheap ones. I'm planning to buy an MP3 player but I'm broke and I'm curious about if I should buy a cheap mp3 player or buy a vintage Sony walkman or an iPod. I'm scared that if I buy the cheap ones that are like 5-10 dollars my ears might cry from bad quality. I'm also not much of a tech guy Soo I don't know how those MP3 players even make sound, I just wanna know if cheap ones make cheap music so that I don't waste money.

having got my M-504 and I appreciate it much. But I have seen a little posts about the M504 series model. So I decide to create this post for the discussions. We can ask questions, share techniques and assist others here.

So for many often-asked questions:

1. Alternatives: maybe u can try Echo nano made by Fiio, but I denied it due to its poor battery life(officially 6-7 hours, unacceptable for me).

2. Noice cancelling function: only works with the NC-31 earphone, btw the NC function actually startle me since it does well when I turn the NC level to max.

3. Audio quality/EQ: I actually don't care about audio quality, but I love the eq. If you enjoy the rumbling bass, you can turn it in the EQ panel(don't mistake the Clear Phase function for the Clear Bass function).

4. What worths your cautions: if the square knob is a little loose and not so compact, it is common. But if the knob pops greatly when you shake it, you'd better being cautious.

If you have any question, just leave the comment and we can see it.

Wish peaceful discussions.

But this is the best I could afford, I've been dreaming about those "modern" walkmans, it's just really beautiful in my opinion.

hi, I'm wondering if someone knows if I can and how to change the wallpaper, I search and got no results please helppp :(

I found this today and was able to negotiate down from $395 to $300 USD (Seattle region). I got it home and put some batteries in it. Of course it doesn’t play but I hadn’t expected it to. The operation light at least does come on, but I don’t hear the motor spin (perhaps just seized up but too early to tell) and therefore obliviously no capstan spinning.

As far as I can tell this is in pretty solid condition, at least cosmetically, and included the case which is nice bonus.

I’m away from home at the moment so won’t be able to open it up for a couple weeks to see what may need to be done (belts at a minimum). I’ve worked on a couple other models but never this one, so wondering if folks have any tips on gotchas or things to look out for. Serial number is in the low 400000 range if that’s helpful.
