Noise Cancelling Headphones - Recommendations

Hi everyone

I want to purchase some noise cancelling headphones but I'm unsure which ones to buy - there are a lot of choices.

I've got some Loops that I use at home which are great, but if I wear them out people often try and communicate with me because they're not visible. I don't mind communicating with people but sometimes I think the visual aspect of noise cancelling headphones would be useful.

I don't have a limitless budget so does anyone have any recommendations for decent mid-range noise cancelling headphones?

Thank you in advance
