player

Hi everyone The jack input of my Fiio Mark 3 being broken, I've been thinking about buying a new player (Sony NW A105 or Hiby R3 Pro Saber), but after reading different articles (some of them contradictory) I'm now wondering about the usefulness of a headphone amp I'm ignorant about all that...

I was thinking of buying the Sony Walkman NW-E394 8GB used for £38. Is it a good buy? Its for listening to MP3s. I have had two Sandisk Players but they both broke. https://www.amazon.co.uk/Sony-NW-E394-Walkman-Player-Radio/dp/B01BBWU596 Thanks
