So here seems to be a really decent deal on some top end ear defenders, essentially with the massively overpriced Bluetooth accessory for free...
The ear defenders are £34 on their own on Amazon / £39.99 at screwfix. The Bluetooth thing is £60!
The reviews for this unit are top tier.
I know it may seem a lot for ear defenders but if your wearing them everyday or need to cut out all sound... Quality makes a real difference and sense IMO.
I needed some for normal uses and also general use on occasion as I am autistic and sometimes struggle with sound.
