I started getting back into Ear buds and IEMs a year ago, and these looked interesting---Dual-driver earbuds, in the design style I prefer. To be honest I was highly disappointed in these when I first tried them out. I was absolutely baffled at how poor they sounded, even after trying quite a number of different ear tips---Not just from the ones supplied, but also my large collection of them from over the years. The ear buds always came up as quite anemic. from time to time over the last year, I would revisit them and try them again---once again, trying different tips/etc. to help them along. I decided to give them one last shot today, and tried an older, very delicate and larger size ear tip that I typically use and it's like someone switched on the lights for the first time. The range opened up and there was finally detail and bass extension!For the price range, these are actually pretty good. I think there's better values out there, namely my go-to buds, the Betron BS10's. For a little more you can get a LOT more ear bud, like the 1More Triple drivers or go with an IEM like the Linsoul KZ ZS10 PRO X 12-driver units.That said, I found the sound to be well balanced and warm, and fairly smooth as far as the response curve. the midrange lacks a little detail for me and they won't be for bassheads, but with a decent amp they can be quite nice. They don't have as much high end sparkle as some others, but I didn't find it unpleasant--- I prefer a smooth response to some people's preference for boosted highs and lows.In summary, a decent choice if you're starting a venture into the deeper end of audiophile ear buds, but make sure you pair them with the proper ear tips---They WILL disappoint you unless you do. This may require you to use aftermarket tips, but it's something you get used to once you start getting more serious about your experience.Edit: I'm revisiting the review and adding a star. I have lots of various makes and models of headphones, and I keep coming back to the Backwins fpr daily use. They're not perfect--- the cord especially is way stiffer and microphone than it should be, but I'll be dammed if I can find better sounding ear buds than these at the price point. Cheap enough to not be busted up if they get ruined, but they have a very smooth and detailed response with very little eq necessary---i'm adding a bump around 1k to open up the mids just a little, as they're a little darker than my taste out of the box. The highs are very nicely detailed without being sibilant, and the lows extend far lower and with more assertiveness than they rightfully should. I'm buying a couple more pairs.

Nice, very good sound. Blows my older ones away.

These headphones/earbuds have great sound. Good left/right separation. Great response in midrange/treble. Good response in the bass, too, except the bass was ever so slightly muddy. But not bad. Definitely listenable. Just sliiiiightly muddy. I'm very happy with these buds @ $30. Great deal. Have not checked the noise cancellation yet - that will have to wait.

The microphone and speaker quality are excellent. I can hardly raise the volume past halfway, as it remains quite loud on my Galaxy Phone.

These are not noise canceling! Sound is quite clear and intelligible. Not much bass for music listening. Ear fit, for me not so good!
