 So today we'll be unboxing the BFU WaveTooth. This is, and I'm just quoting from the packaging here, first waterproof BT headset can swim, IPX8 certified to waterproof, 3 meter, 24 hours, noise rebound technology makes clear talk, 13 hours extra long talk and music time, and it has stereo earphones included for music, as well as waterproof earphone included. Check that out. So this is a pretty unique product in that, okay, well here, hold on, let's go through all the, well there's no need to, okay, it has a 360 milliamp hour lithium polymer battery. It has, okay, we've covered the, okay, standby for 240 hours, and it uses Bluetooth version 2.1. Okay, so we'll have a look at the, uh oh, hopefully that piece of paper is also waterproof because it fell in the very scummy water that's near our office here. I'm just gonna, whoa, that's dirty water. Okay, oh, lifetime warranty. And you know what, I think the card is waterproof. Nice, it's plastic. Sweet. Okay, so I'm just gonna, yeah, dry that off there, and please inform us, serial number and buy date, buy Facebook. That's to get your lifetime warranty, no way. You register your lifetime warranty on Facebook. Okay, they've also got some terms and conditions for their warranty. Okay, yeah, yeah. Alright, and then that's not in English so I can't read it. Okay, so here we go, we've got some random stuff there, we've got, what else is inside here? So, here is the actual Bluetooth device itself. It has a little clip. So I guess you could clip that there to your swim goggles. If you were swimming with your Bluetooth headset, there's presumably volume up and volume down. Neutral button or Z, Z, okay. Let me see what else do we got here. So we have one set of waterproof headphones. So this is for listening to music on your music enabled, Bluetooth enabled phone. Okay, left and right. I can tell you how comfortable they are. Hey, that's not bad. Okay, okay. Then, wow, that's a really noisy truck behind us. Sorry guys. Then there is a USB charger cable. So that's probably going to plug in here. There you go, so that's how to charge it. I've seen these adapters before. Then we have the actual Bluetooth earpiece bit, I guess. Well, how does it actually hear you? Hold on. Well, this can't be, okay, no, talk and music time. Well, it has to be able to hear you somehow, right? Hold on, we better pause this one while I figure this out. So I took three NCIX employees and the manual here to figure this out. We'll go through the manual in a minute because it's definitely worthwhile. But I do want to explain exactly how this device works. So you can see out of the box, we took the waterproof bag, which uses a double seal as well as a folding flap of plastic to keep water away from your iPhone. This is the cameraman's iPhone. Okay, so we got two ziplock seals here and then we just put the iPhone in there. You fold this up and then you just use a Velcro to keep that shut. Okay, and then the way that the WaveTooth itself actually works is you use the Z button in the middle for pairing to answer and to make calls. And then this changes your audio track and then this is the volume button. Oh, apparently I just made a call. Sorry, sorry, Tim, don't answer that. Don't answer that. Sorry, it was my bad. Okay, I hung it up now. So that's what we were using for testing. Now the microphone is actually here. All right, so something that I want to explain about this is it is waterproof. Now bear in mind the mono earpiece is the only one that's waterproof. The stereo one is not. It's waterproof so you can kind of like listen to music, okay, while you're swimming or whatever it is you're doing that you need a waterproof sound system for. But you can't actually talk on it in the water, which makes sense. So suppose someone calls you, you hear it in your Bluetooth, you get out of the pool or you get away from the water and then you talk into the microphone and it should hang around your neck or it has a clip on it where you can clip it to your collar or something like that. So and then this has a strap on it so you can keep your phone somewhere conveniently close by. All right, so now let's go through the manual that helped us to determine all of these things. First of all, the microphone. It is made waterproof and don't worry water go inside. Don't put sharp things into this hole. So make sure you do not put sharp things into that hole. Okay, let's find out what else. Okay, sea rust and sweat may rust the... Sea water and sweat may rust the headphone jacks. So be careful with that if you go swimming in the ocean. Don't pair to K-touch and China cell phones. That will make BFUZ misfunction. So make sure you don't do that. Not recommended for use with water skiing as it may hit your body. And there's a rubber band here to prevent sands going inside. You can use your own headphones if you prefer. Okay, the wave tooth's core is sealed. Just pour out water and keep using. Okay, a headphone maintenance. Please take special care on the headphone head because it is very weak. Don't force on here when you insert it. So be very careful with that. Use clean water to clean it out. Let me see if there was anything else on here that was very pressing. Oh, please ensure the jack hole is dry when you charge the battery. Whenever you're charging the battery, ensure the jack hole is dry because... Remember, you do use the headphone jack hole in order to plug in the USB adapter. See here? Okay, so that plugs in there. Alright, so I think that's pretty much everything to say about the wave tooth. And thank you for checking out the unboxing. Don't forget to subscribe to Linus Tech Tips.
