This little bluetooth earbud is pretty much everything I want. It is very light, very small, has exceptional battery life, is easy to charge, can connect with multiple devices at once, switching between them on the fly, and doesn't hurt your ear because it is held in only by the rubber bud.PROS:Extremely SmallGood Bluetooth RangeLoudLong Battery Life (4+ Hours Easily)Wireless Charging (sort of)Two USB ChargersConnects with Multiple DevicesCONS:Sub-par Sound QualityCan Fall Out of EarHonestly, there is little more that I would want from this earbud. Does it fall out of your ear sometimes like others have been complaining? Yes, if you are walking or running, you'll probably have to push it back in with some frequency. That doesn't mean it comes flying out unexpectedly, it just shakes loose, just like most other earbuds, and that's why some designs have rubber attachments that wrap around your ears. However, I didn't buy that model, I bought this one, and having to push the bud back in from time-to-time is far less annoying than having to strap on a crazy hearing-aid style wrap-around, personally. Also, since it comes with three different sized rubber earbuds, it is moderately customizable to your ear.The "wireless charging" is awesome. How it works is the little USB chargers have two prongs in the center of an indentation that has a magnet behind it. The earbud sticks to the magnet and slides onto the prongs. If you practiced, you probably could throw it at the charger and have it start charging. I really can't stress how simple it is to attach, it's mildly magical. The magnet latches on and about a second later, the blue LED on the earbud turns and you know it is charging.Pairing it with a bluetooth device is simple: When the earbud is off, hold down the button for about 5 seconds. At about second 3 you'll hear a slightly accented voice say "Device On" and then at second 5 it says "Device Ready to Pair" (I may be paraphrasing here). At that point you need to tell your bluetooth source (be it your phone, or your laptop, GPS, car, whatever) to start searching for a bluetooth device, and it should find a GoNovate G8 and then pair up after about 5 seconds or so. Then the voice will say "Device Connected" and you may even see the G8's power bar on your bluetooth source's screen. I can confirm it does this with the iPhone 5s, but does not with the MacBook Pro, for whatever reason.You can have the G8 paired with multiple devices and run them simultaneously. HOWEVER: It will play audio from only ONE at a time. So you could be listening to music played by your computer, that would be interrupted when your phone gets a call, for example. Not as cool as playing both at the same time, but still useful.Basic operation of the G8 is pretty simple: Hold down the little button for 3 seconds to turn it, listening for the voice prompt. You can pause or play music by clicking the button briefly. You can answer calls by clicking the button, or deny them by holding the button for 2 seconds. Plus, like starting it, you shut it down by holding down the button for 3 seconds. That's it. Just 1 button with different hold times, and everything is identified using voice prompts.MY ONLY NEGATIVES:Firstly: The sound quality isn't great on this thing. I would describe it as a bit "muddy", with a lot of different tones bleeding into each other. High notes are reasonably crisp, but voices and anything pushing into the bass ranges tend to lose distinction. Personally, I use the G8 to listen to podcasts, which don't require great sound quality. Everything is easy to hear and understand, but you aren't going to want to listen to complicated orchestral pieces on it. The G8 is designed for convenience and portability, and at $18, it is really cheap. It's not exactly a surprise that it can't match my over-the-ear, Sony Studio Monitor Headphones. What is crazy about modern technology isn't that the G8 isn't as far away from those Sony's as the price would indicate. It's no masterpiece for sound quality, but it is sufficient, and that's a long, long ways away from cheap headphones of twenty-years ago, or even ten, or possible even five-years ago.Secondly: The original shipment arrived with a Flexible USB charger, and a non-adjustable Car USB charger. The Car USB charger worked perfectly, the Flexible USB Charger didn't fit the G8. So I contacted the seller and the immediately shipped me a second Car USB charger, which also works perfectly. I don't know if this is the case for all of the Flexible USB Chargers, but I must commend the seller (in this case: Ken from GoNovate) for rapidly responding and correcting the issue by providing a second Car USB charger for free. Now I have two chargers, as advertised, and they both charge the earbud perfectly.CONCLUSION:It is cheap. Its battery lasts a long time. It is very easy to use and setup. It doesn't hurt your ear. Charging it is very easy. It is cheap. The sound quality is good enough to not be annoying. It can be used by multiple devices. Plus: It is really quite cheap.
