I have a pair of Phillips Fidelio X2HR for my PC where I listen to most things; an unexpected brand compared to the likes of Sony or Sennheiser. I'm considering an upgrade to a close-backed pair of headphones since I don't live alone and my PC space is nearby to the kitchen, so I would like to block sound out.
In the gym out back I use a Google Mini. Living where I am now I haven't needed earbuds for public transport so I don't have any. I will eventually buy a pair for when I go camping and want to watch something on my phone.
