ShureAONIC 215 TW2 True Wireless Sound Isolating Earbuds with Bluetooth 5 Technology, Premium Audio with Deep Bass, Secure Fit Over-the-Ear, 32 Hour Battery Life, Fingertip Controls - (Gen 2) - Black

I originally picked up the Shure TW2 to go with my SE846s so that I could go to the gym and wear audiophile-quality earbuds. But then I noticed I could've gotten these for not much more than the regular TW2 price, and I'd get AONIC 215s for cheap. Score!I absolutely love these earbuds. Are they as good as my 846s? Obviously not. But I don't need them to be. I use my 846s for gaming and audiophile stuff; I use my AONIC 215s for working out and mowing, and they're PERFECT for this. Honestly, I think they'd be fine for just about anything, but if you're into high quality music listening, then you'd probably want something just a little better than the 215s, but that's only because I'm an audio nerd. For most people they'll probably be an improvement over what most people have been listening to music with.But, again, why I really bought these was for the TW2s, and it's amazing. Because high end Shure IEMs come with detachable wires, you can use the TW2s with anything in the Shure line-up (so long as the wires are detachable, of course). So I can switch in my 846s or my AONIC 215s depending on where I am or what I'm doing, or keep the AONIC 215s in my gym bag while I keep my 846s at home. Replacing the IEMs are super easy. Simply pull them off, snap the new ones on. No issues whatsoever.The battery life is very good. I can go about 8-10 hours on a single charge, and the case (which is VERY bulky, but they're very protective and has a sizable battery) has about three extra full charges in its battery, so you can easily go on long flights or trips and not have to worry about running out of battery.I also like the app. It's simple to use, and switching between IEM models is as simple as snapping the new ones in and then going into the app and selecting the new model. You'll have to do that because the TW2s will transmit slightly differently depending on the model, which increases or decreases the volume (and other EQ info). On that note, the app itself is highly customizable for the sound, both with many presets for higher or lower bass, treble, etc and you can also customize your own presets for your own preferences.So whether you're just in the market for entry level audiophile earbuds or if you're already a Shure devotee and just want TW2s, I strongly recommend picking these up. You get an amazing IEM in the AONIC 215s for cheap while you also get the TW2s, which you can use with any other Shure IEM (that has detachable wires). Given the sound quality and EQ options, you can't go wrong with these, and that's coming from someone who has both the entry level IEMs like the AONIC 215s and the super expensive professional/audiophile quality 846s.

I needed to get new wireless earbuds after my Bose Sound Sports stopped charging. I had tried their newer model but whenever I ran it fell out of my ears. With these that is not a concern at all. When running and working out with them they stay very secure and require little correction. They also work well with glasses and sunglasses. The only problem is for this secure fit it takes a while longer to get them put on. First getting the wireless adapter over your ear then fitting the bud into your ear channel.Sound Wise, these are very good but with one big downside. I had thought my Bose had good sound quality but with these Shure earbuds, i have never heard music crisper. With these, I can actually hear the difference between an HD and an UltraHD song on Amazon Music. The biggest downside of them though is they have a very weak bass. Even trying to use the equalizer to improve bass profile makes almost no change.Functionally these are decently user friendly. Other than volume control users can do everything with only one earbud in which is a nice feature, but would definitely be nice if all functions can be done on either ear bud, especially if your carrying something in one hand and can't free it up. I also like their slimmer profile since they don't stick from my ear as far as the Bose do.

I paired them up to my Samsung S8+ and I was greatly disappointed by the sound quality. I could hear the treble and mids fine, but there was very little to no base. The whole reason why I decided to spend $247 on these earphones was because they are advertised as having deep base. I contacted the manufacturer and was advised to mail them, at my cost, to the service center in Wheeling, Illinois. I am in San Diego and I didn't want to spend any more money or time to send these earphones to Illinois, so I opted to just return them for a refund. Now I have to wait to see if I get my full refund....
