Room for improvement
I bought this almost a month. The sounds quality is no doubt on it, I love it! However, there are some areas still room to improvement like; notify when ‘low battery’ instead if ‘no battery’ and straight cut off. Also, the maximum volume is not that really enough to for me. (I using Spotify)

Exactly what I was looking for.
After an exhausting search for an MP3 player I finally stumbled across these headphones. I was on the fence by the mixed reviews but at the end of the day they had what I was looking for so I got them on sale. I'm not gunna lie, it took me awhile to figure out how to get music on it which was actually the feud between my Surface and Huawei phone not the headphones. Now I have tonnes of songs on them , used them last night and they didn't budge once. My only complaint is they are pretty ugly and it would have been nice to see some options for the ladies instead of just black. Girls like pretty things :) highly recommend!

Expected More
I Brought the Walkman series in a duty free shop in Bangkok airport. The expectation from Sony was really high for me. Even the shop guy convinced me to buy Sony. But now I feel there are three major issues with it...
1) The inner ears start hurting so badly that after maximum an hour its a battle to wear it for more longer time. mostly like Pain vs need kind of a scenario.
2) The battery capacity of the Walkman is quite poor, hardly 2.5-4hrs backup.... depending on the mode... if on Bluetooth its just 2.5hrs otherwise it might go up to 4 hrs.
3) The sound output is not that great.
