Several months ago, Sony did away with its Sony MDR-W08L Vertical In-The-Ear Headphones.
Yes, I know they're old school, but the sound is good and they stay in place, all the time. I have run thousands of miles with these headphones and can attest they fit well, lock into place, and offer a nice mix of bass and treble.
I used to buy 5-6 pair at a time from Amazon, at about $8 a pair. I'd run them hard and sweat them out, then go to a new pair in six months or so.
Imagine my surprise when I tried to re-order and found out they were discontinued. I actually went as far as to call Sony, where a disinterested customer service rep tried to steer me towards Sony's more modern wrap-around-the-ear model. I have tried several models and brands and don't appreciate the fact I have to readjust them every 5 minutes. Once you've been on the roads and trails with the Sony MDR-WO8L, anything else is second place.
It's easy to see the value in this product. The re-sellers who still have some in stock are selling them for $89, or more.
I do understand change, but it's hard to understand why a product that worked well is obsoleted by products that don't work as well.
Sony, if you're out there, please reconsider and bring this top performer back on the market.
