Tempting to think you're buying from B&O themselves with such a similar name, but you're not

Could it be fake?

I believe you are buying from B&O here - check out the copyrights etc on this page, which mentions it's the official store etc...

It's a shame alot of the phones are starting to get rid of the headphone jack. iOS lighting - Android USB-C

Having once worked for Philips I can tell you that B&O were nothing more than a designer of fancy boxes, and the internals of the things were all made by Philips, and just the generic audio which could be bought at a fraction of the price if it had the Philips badge on it.

There's little reason to think anything has changed, but headphones aren't exactly ever going to be a design classic, I do wonder what is actually inside these, probably a cheap Sennheiser set with a B&O badge.

I have b&o earphones.
Not impressed, similar or cheaper shure earphones beat them everytime.

I've been through a fair number of headphones - (unable to find ones I liked).

Got these a few months ago - they are keepers.

I bought mine from here about 3 or so months ago. currently my main portable headphone that I use. They are actually really impressive, have a really nice spacious natural sound to them, would highly recommend them for £129!
