I regularly use a David Clarke H10-13.4 and a Harry Mendelssohn HM40.
Both are fine, very little to choose between them, the HM40 is cheaper.
Transair or Harry Mendelssohn are both good shops to buy from. Flightstore is fine in person, but they have a bad reputation online.
Bose are magnificent, but expensive, fragile, and OTT for a new or low hour PPL to be frank. I did borrow one for my CPL, but still do most of my light aircraft flying with an HM40, and can still pass the hearing test for my class 1 regularly after 13 years of using an HM40. I tried an experiment last year - swapping between the HM40 and DC10-13.4 a few times on a longish trip to see the difference. Basically, there wasn't any.
