Hi,
This is a little beyond your stated budget, and it may not suit your use-case.
https://minirigs.co.uk/speakers/bundles I picked up the 2:1 system a few years ago as I was travelling so much – it meant I could get decent sound wherever I was without carrying around a huge system. Now that I’m more staled I find myself still using them as they are so versatile and the sound is so good.
They can be used with bluetooth (pretty good sound and battery life), or wired (better sound and excellent battery life).
Maybe no good for you, I just thought they were worth you taking a look. I love them, and have had no regrets about buying them despite the high price.
edit: Hmmm, seems like a cannot do a link for some reason. The speakers are minirigs from minirigs.co.uk, and I was specifically recommending the ‘two stereo speakers + subwoofer’ bundle.
