Works with OnePlus 7T (RIP 3.5mm headphone jack). Bought mainly as a backup for my Bluetooth headphones in case I run into battery issues. The earphones come in their own carrying case with 3 different tip sizes. There is also a pocket clip to attach the 3.9ft cable to you. The cord is good and long so you can keep your phone in your pocket and not choke. The headphones don't come with silicone ear grips, but the standard ear size fits me perfectly. It's reliable and doesn't fall out when I shake my head hard. I haven't worked with them yet, but I hope they stay. I'll be using it primarily on my desktop, as long as it stays there I'm happy. It sounds really good with my music and Spotify. Judging by the product page there is a DAC but I can't tell as I'm not an audiophile. At maximum it gets very noisy and can probably cause damage if you're not careful. The headphones have a controller. You can increase/decrease volume and play/pause. On the OP7T, you can skip to the next song by double-clicking twice. If you press and hold , you can bring up Google Assistant. Triple press did not skip to previous track on this phone. It's okay if I can quickly skip to the next song with a double tap. I also have an OP5T but these headphones don't work with it. The OP5T does have a headphone jack though, so that's fine. All in all I recommend them!
