 Hey guys, Thunder E here and we're taking a look at a brand new pair of in-year wireless buds from Sennheiser, the CX-400BT. Want to thank Sennheiser for sponsoring this video. I am excited to see this, but guys, before we continue, don't forget to like, share, and subscribe. Now let's jump in and find out more. These are true wireless earbuds from Sennheiser that really hit a certain point for you. Now they're currently priced at $149 and if you're thinking about something to pick up within that price range for the holiday season, yeah, you definitely should pay attention. So let's take a closer look at what we have here. Now they're coming to you different color variants, black or white. I do like the white color and I wish more manufacturers would take this path in making color variants for, of course, the true wireless buds. Does have USB Type-C charging in there, so you get some faster charging. The earbuds themselves are nice and clean. I definitely love the looking white. You've got the Sennheiser logo on top. With the case, you get 13 hours of battery life and with the earbuds themselves, you get seven hours. So in total, 13 hours of use, but quite a long time while using the earbuds themselves. They have a very comfortable fit, so when you take them out, you place them in your ears, they're comfortable and they automatically turn on and sync to your smartphone. Now, Sennheiser does have an app that you can use with these earbuds and the app is really nice and a bit simplistic, but I like the simplistic nature of the application. You can go in and customize the controls on the application, so you can customize your playback function, your call answering function if you want to, and you've got the EQ settings as well to customize the EQs the way you like. Now, as you can clearly see, my EQs are neutral. I like it that way, but you can mix and match whichever way you want to go. Now the main thing you guys are probably wondering is what about, of course, audio quality. How good does it sound? It's really good. Now, this is Sennheiser we're talking about. So they've got a good pedigree in terms of audio and you've got really nice separation between your highest mids and lows. Now, the mids are not, say, as sharp as the momentum, which I definitely love those, but these come out really well. You get a full reach of all you're listening to within the song, so you can hear those highs. The mids come out pretty well, and the lows come out really striking overall. So very nice overall sound balance, especially listening to music at that neutral soundscape. Now in terms of noise cancellation, there is none, but the isolation is really good. Once you play music, it really blocks out everything, so you can just keep doing what you need to do, enjoy the music you're listening to, and have a good time. Hey guys, this is a quick mic sample of the CX400BT from Sennheiser. He has an idea of how well it sounds, and giving you a clear indication of what you're getting when you're using this for voice calls. I definitely recommend these. I think these are worth picking up, so if you have any questions or any comments, let me know guys. Don't forget to like, share, subscribe, and always enjoy your entertainment.
