Can't have very good stereo separation if that's true. You would only be listening to one channel unless you are listening to your music in mono. Or perhapes you don't listen to music on them.
I have a refurbished pair of BeatsX Wireless in ear headphones which I bought online for just $9.00 more than the Apple EarPods. Yes they have a cord between them which I find an advantage as I can use the controls with either hand and they never get separated in my bag. If I take them out I can leave them hanging around my neck meaning I'm not always trying to remember where I put them. All in all I think haveing two separate earphones is just an invitation to loose one of them and what are the chances of being able to replace just one.
As for sound quality I can not even begin to compare the EarPods to the BeatsX. They make the EarPods sound flat and tinny, which in my mind they are. I can even activate Siri with Remote Talk and they came with a Lightening to USB-A charging cable. So before you praise the Apple Earpods too highly at least look and compare the alternatives. eg. Walk into a Bose store and try their SoundSport range of Blue Tooth EarPods, then you'll really be able to evaluate the Apple EarPods.
Whatever works for you.
But just fyi, people who use the one Airpod mainly do it to charge the other one in the case. It's one of the main benefits of them.
If I needed to use one Airpod, I'd only use the other one for phone calls. If I was listening to music, I'd just charge both of them at once, as listening to music through one isn't enjoyable.
The cord on the older Earpods actually increased the chances of them falling out, as they pulled on the buds. Most people find Airpods an improved fit. Some find them just as loose as the Earpods, but if anything, I've read more stories of the Airpods fitting more snug than less.
Sound quality to someone depends on what they've been exposed to prior. If the Earpods (wired) are the only buds someone's heard, then the Airpods will be an improvement.
The Bose may very well sound better, but the overall package of the Airpods within the IOS ecosystem, for someone who's happy with the fit/sound quality, will be all they need.
