While I like the overall sound of the TSMR-3 Pro, I can't seem to place them in my ears for more than a few hours. I'm hoping to change the stock IEM tips for more comfortable tips. What tips go well with these?

I decided to buy a refurbished iPod Classic 5th gen. Now, I'm just wondering which IEM would go best with it. I listen to mostly rap, R&B, and podcasts.

While they are still a great set of cans, I am looking to upgrade my ATH-M40X's. I mostly listen to hip-hop/rap, need close-end headphones, and will be using the Cowon Plenue D2 as my DAP. Price range: $200-300. I'm willing to buy used headphones as well.

Which one should I get? I use the ATH-M50's but hope to upgrade them in the future.

Do you see any differences in the overall sound quality?

Why

Which MP3 is the best? What are the pros/cons? Which ones would you pick?

Are there any cricket-compatible phones I can use as a MP3 Player? I'm trying to use it with the Ibasso it101.

Gotcha. I'm thinking of buying a Sony NW-A45 Walkman--do you think that will make a difference in terms of sound quality? Or would I be good using my android phone?

What do you use as your music player?

Which one has a better build? Which one would be better for the genres I listen to? ( hip-hop/rap, EDM, and podcasts).

Are they durable though?

I'm thinking of getting the ibasso it01

How do they compare to audio technica ath M50x?

I forgot to add--budget is 100-150
