F10 Mini Bluetooth Earbud Smallest Wireless Invisible Headphone with 6 Hour Playtime Car Headset with Mic for iPhone and Android Smart Phones(One Pcs)

This is my first Bluetooth device, and I am really happy with it. Delivery was on time and package in great condition. It was fully charged in 20 minutes, and the menu options took a few minutes to get used to. It is all one button with different clicks/holds to for different options, so you need some practice to know how long to hold.I paired it easily with my Moto G (3gen) running Android 6.0 and my Samsung laptop running Windows 10. It connects to both devices and easily communicates to both at the same time. I played music from Spotify on my phone for a few hours, then switched to listening to Hulu on the laptop. 5 hours later, and I'm still on the first charge. Sound quality is satisfactory for me, but I'm no super user of audio equipment. I don't plan to answer calls with this.I have pretty small ears, and based on the reviews here about the fit of the earbud, I ordered some triple flange ear tips in size small. They were a tiny bit too long, so I ended up cutting the third tip off, so with the two tip flange these fit securely and fairly comfortably after a few hours wearing it. I did some jumping around and head wiggling to get it to fall out, and it stayed put. I wore it to the gym and it worked pretty well. It stays in just fine when moving around and is comfortable. Of course, to block out the annoying gym music (untz untz untz), I had to also wear an earplug in the other ear, which worked fine. I could still hear the overhead music, but it was blocked enough that I could ignore it without turning up the earbud volume too much.I also use this at work, and like that I can still be present and responsive to my coworkers if needed, while still getting lots of work done on focused tasks with enjoyable music. I also have some mindless tasks that allow me to listen to podcasts at the same time. All in all, I really really like these, but one thing I would want is a lighter color so people will stop staring at my ear as though I'm ignoring them. Oh, and some way to find out the remaining charge on the battery. Battery Low doesn't start until it is about 5 minutes from dying.*Update* Count me among those who lost the tiny earbud. I put it in my pocket sometime after lunch, and by the end of the day I didn't have it anymore. I could use some way to store it more conveniently than my pants pocket, because the hard case is too bulky to carry around. Of course, I bought a new one. The price is good for something so easy to misplace, and it will be nice having a second charger to keep at work.*Update* I ran the second through the laundry in May. Bought 2x of a different brand because it came with more chargers, exactly the same body/software/performance/price. More chargers means I keep them on a dock wherever I am and less likely to keep it in a pocket. Two for the car, two for the work desk, two at home. I'd still like some way to keep them docked on my person when not in use, a lanyard or bracelet or a smaller pocket pouch...

Updated 2020 after over a year of usage:UPDATE: I've now bought 4 of these, two for myself and 2 for family as gifts. I own a pair of Apple Air Pods, and after 9 months of use (non-pro edition), they are beginning to glitch and show signs of age. Compare this to my Focus Power earbud and it's night and day. Apple has Trillions of dollars to make great gear and this small startup makes an earbud that is smaller, fits better, and lasts through the test of time.I just ordered another FocusPower earbud (b/c I tend to lose mine at no falt of the product; I'm just forgetful with technology devices). I use it to supplement my aging Air Pods. For this price, I really don't think there is anything that comes close to this product. I looked at other options and the size of the earbud is HUGE and very unattractive... talking about Bose and JBL...If possible, Focus Power really needs to build on what is an excellent product in this category by making a two earbud edition and continuing to produce the single earbud with longer battery life and a different low battery indicator. The "Low Battery" voice is pretty annoying and could be replaced by a phone notification or something. Airpods literally just die with no notification so that's always an option too... I'll be using the mic on my new set and will update this review to let everyone know how the mic quality is for calls and zoom meetings.ORIGINAL REVIEW-THE PROS: I bought this not expecting much since it's only ~$25. I thought the fact that it came with one earbud was a little bit lame, but in reality this is how I use many of my headphones anyway when I'm at work. I have found this headset to be very quick to connect with devices, great sound quality, given it's only in one ear... , and it never falls out of my ear which is awesome.THE CONS: It could have better battery life. That's honestly my only con to list. I've used mine for a few months so far about 3 to 4 times a week. I make sure to have the little charging usb plugin with me so I can always keep it powered. Just plug it in when you walk away from your desk or whatever. I'd guess that the battery lasts around 5 hours of continuous play, maybe more, maybe less at times.SUMMARY: This is a really cool earbud for the price. I've run with mine, showered with it in my ear, use in the office, and use in the gym. It's really handy, and for the price point, I was impressed with the product feel and function. I give it an honest 5 Stars for all these reasons.
