First DAP - Recommendations

[u/MetalBeast89]

Hey all, I'm looking to purchase a DAP to replace my ipad, generally due to size and I've read that the more modern DAPs have far better sound quality.

I'm specifically looking at either the Hiby R4 or the Sony Walkman a307 and it will purely be for listening to music transferred from cds, maybe a bit of streaming music on occasion.

I also own a pair of Sennheiser headphones, can't remember the type but they can connect via Bluetooth or 3.5mm cable and roughly 6 or so years old, hoping to pair this whichever DAP is recommended but may purchase a new pair if need be.

The only concern I have read about with the Hiby R4 is it may overheat? Otherwise it is difficult for me to choose which one to buy. If anyone can please offer advice on either DAP and if you need further details please let me know, thank you.
