sorted byA few things:
They are quite tight (me = adult, medium head) and the cup isn't generous around the ear. So they fatigue quicker than my qc-45 (i know comparing apples and pears - but gives an idea).
Sound is good wired and not wired. Easy to use. Feel of quality. Good battery life. Decent accessories (better cables than Bose delivered with the 45s).
The refurb will be like new and boxed (looking at you centres direct).
I returned mine as the ANC was problematic - a lot of distortion on the left ear which made for a poor quality listening experience. That said, I hope they replace with a good pair as I really like them! (edited)
When I change to UK it takes me to a different site which doesn't have these refurbs. Can anyone help with the link please?
I could now easily wear these all day.
My last one were Huawei big ones last year so as long as similar to them I'm happy
Silly Beats Flex are 10x much better than these crap
Beats Flex are earphones so not sure if you're confusing these with some other product?
From soundguys.com review (reviewed at $199):
"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise cancelling is good and sound quality is great—quite rare at this price point."
ANC is not the best compared to both Bose and Sony that I own but you can say it's good enough I guess.
