Wireless Headphones. Need help!

[deepbreathsanddeath]

I've decided I need to invest in a pair of wireless headphones. My girlfriend likes to go to sleep fairly early while I'm a night owl and tend to watch movies late at night.

The light she can deal with. She has a mask that she's happy to wear but I feel bad about the noise. Often I'll just end up turning everything off long before I would like to so she can get to sleep.

Problem is... I know jack shit about wireless headphones. Can I get some advice on what to get? Keep in mind, I'm pretty broke at the moment but I can put them on layby. I'm not looking to go expensive but I do want good sound quality without much sound leaking out if that's possible.

Keep in mind I live in Melbourne, Australia so I must be able to get them locally.

Any advice would be appreciated thanks
