I still don't understand why people pay so much for what is exactly the same sound-wise as the standard included earphones. I got the BeatsX and they are cheaper and have way better sound, combined with the W1 Chip!
As an owner of BeatsX, which I'm assuming the batteries are now shot on because I can't even reset to charge them, lasted less than 2 years using them an averaging about 3 hours a day. Most days about 2 hours. So I'm hoping airpods batteries will last longer.
I feel like you have to consider more than just sound when comparing the X's with airpods. Assuming you are an iphone owner, airpods should be more convenient. From what I've heard, just ordered my first pair, you literally take them out of your case put them in your ear and music starts playing. Beats X have one of the worst on off switches I've ever used, also easy to forget to turn them off, draining the battery and missing notifications on your phone because they are still going to the headset.
Not having a wire at all should lessen them tugging out of your ears which I found annoying when running. The fins offset that but also a bit less comfortable. Airpods, from reviews I've read are one of the lightest and most comfortable wireless earbuds to wear. I'm personally really looking forward to not dealing with that wire around my neck.
Sound wise I've recently started using the current earpods, hadn't used them really since the old circular ones way back in the day. They actually don't sound that bad. I was especially surprised at sound stage/sound separation, and how they seem to push vocals. I do find they seem a little under powered maybe? The highs can distort a bit at really high volume and both the low end/bass and highs could be more detailed.
I wouldn't say the X's sound significantly better though there is an advantage having sealed earpiece, though the open design on pods tends to be better for sound stage IMO. I'm also having a hard time remembering the X's sound now. For the price, especially when on sale, the X's are definitely a solid deal. Probably overall sound a bit better than airpods, will fit most peoples ears better especially when exercising though they do not like sweat and water as the adhesive on the driver screens was coming off on mine.
Personally, I'd probably buy jaybirds vs beats X since they should sound better than the X's and have better water resistance for working out. But for I want to see how airpods can handle going for a run. If they stay in I'll stick with those as my commute/exercise earbuds. Maybe buy a set sony wh-1000xm3's if they go on sale for commutes and at work.
