Or saving even more......
Why not try auction websites for H10-40s? No longer available new, but if you buy the latest version they'll last almost forever (mine are 20+ years and going strong). To tell if they are latest type look for flattish round volume control button - not the cylindrical one that sticks out more. Head pad is also different - new one is ridged from front to back, not side to side. More comfortable!
Expect to pay between £90 and £120 for a good pair. Sometimes there are almost unused sets to be had. Look for good photos that show unmarked ear domes, and clean pads inside the earpieces.
If they don't have gel ear seals when you get them, invest in the undercut comfort set, and you won't regret it. Will last you until you move up to jets, and then you can resell and nearly get your money back 😊
