A few years ago I bought a Philips DAP from a local distributor, warranty and all. And it wasn't cheap either, around $60-70 at the time. As it turned out, the DAP had a firmware bug - which was minor for other people apparently, but rendered the DAP useless for me.
First, it took me 15 days of haggling with Philips customer support. At first, of course, they misunderstood my problem completely. Then they presumed I was using the unit wrong. Then they demanded I send videos and proofs of the bug. Then finally, after days of silence I got a reply basically saying: "Yes, it's a bug in the firmware. Deal with it."
Oh, and the extras in the retail package? A USB charging cable. They didn't even include the complimentary earphones, as cheap as they'd probably be. Even a $17 Ruizu gave me one.
When I went to return the unit to the local store, they wouldn't accept it. I couldn't even exchange it for another DAP (I was even willing to pay the price difference). The only thing they could do, the clerk said, was send the unit to their official repair shop and have the tech guys look at it for any defects. And since there weren't actually any (software bugs didn't count), I was stuck with a brick worth $70. So the warranty was worth diddly-squat.
Even before that, when I was a teen in 8th grade, I took a substantial portion of my savings and bought myself a Sennheiser earbud. Don't remember the model, but it was around $30. The thing, with the usual brand names budget cables not being worth a penny, crapped out on me rather soon - the left earbud went dead, despite me being extra careful with them. Guess what happened when I went to the local store to complain? Yeah, you've guessed it.
Extras with that Sennheiser? Honestly, I don't even remember if I got extra foam pads, as I remember wearing them padless for a time - which begs me to presume there weren't any in the retail box.
A few months after that, I went for another Sennheiser, this time over-ear and even costlier, since I thought I didn't go high enough price-wise the first time, and had it coming with the cheap cables. As it turned out, the cables on this one were equally as bad, and again a driver failed, only the right one this time. Did I get my money back? Or a replacement unit? No, I didn't.
And extras? Perhaps a carrying pouch, something? Nope. Chuck Testa.
So, warranties from my local distributors are pretty much worthless to me. In fact, I avoid dealing with local distributors as much as I can. They're more expensive and they have a far poorer selection of everything. In fact, they can all go bankrupt if you ask me, the way they treat customers.
And, as imagined, I've acquired quite a dislike for the brand names in the process, after getting the middle finger for putting my trust in them (there were more earphone failures after that 2 Senns). What's more, the cheapest KZ I've got, the ATE-S, beat both Senns in sound quality (and I'm pretty well sure time will prove it will beat them in build quality also).
On the other hand, the Chinese sellers on E-bay and Aliexpress treat me as an actual valued customer (albeit in broken English). That's also why, for my step up in IEMs, I didn't even try local stores, or brand names. I went straight online and - after extensive reading - got myself a PMV A-01 mk. II which I presume I'll be a very happy owner of, probably far happier if I'd had spent that money on another brand name.
EDIT: And look at the amount of "luxury" the Chi-fi IEMs had got us expecting: detachable cables at a price as low a $10-15. If a Chinese IEM costs $20+ we expect detachable cables almost as a right, not an extra. But do people expect such cables with a $30, $40, $50... even a $100 brand IEM? No, they don't. They don't even regard it a shortcoming!
