Anker SoundBuds Sport NB10 Bluetooth Headphones, IPX5 Water-Resistant Bluetooth Headset with Adjustable Neckband, Sport Earbuds with Mic and CVC 6.0 Noise Cancellation for Work Out, Gym and Running.

I've owned hundreds of dollars worth of bluetooth headphones ($20 to $40) at a time over the last few years. I'm an avid runner currently nearing my first half marathon, and I sweat buckets when I run. I also lift weights a couple of times a week. I've owned QY8 (terrible), AYL (okay), Blayz (decent), and several others I've forgotten.Background:Years ago, I got really awesome headphones in the form of these waterpoof beasts https://www.amazon.com/Sony-Walkman-NWZW273S-Waterproof-Swimming/dp/B00I05EFMG. With these I kickstarted my running habit and began to enjoy the sport more. From a physical standpoint, these are the best headphones I've ever owned. They are incredibly comfortable, lightweight, and easy to control aside from turning them on and off. The downside is that they are not bluetooth, and thus I can't use them with all my cloud-based music easily. Another downside is that they have trouble charging due to contact corrosion that has amassed over time exacerbated by sweat, and it's not great that they use a proprietary charger. If Sony made a bluetooth version of these in this same form factor, I would buy it in a heartbeat. However, Sony does not make a bluetooth version of these.Anyway, I knew that the rigid-back formfactor could really work well from my experience with the Sony headphones. Unfortunately, Amazon is full of terrible bluetooth headphones with fake reviews that make it hard to dig through them all, and most manufacturers make the kind with a soft cable connecting them. I really think the only reason that style took off is because it is cheaper to manufacture. Anyway, after trying lots of disappointing headphones, I decided to give these a shot when I was weighing getting some bone conduction headphones since my wife (also a runner) got some.I heard about these from a facebook ad oddly enough, and later found them again on Amazon. I was frustratedly comparing headphones when I stumbled across these the second time. The reviews appear to be genuine, which is rare in this product category. I've also owned Anker products in the past, and they have mostly been great. Even when one wasn't, they tried their best to make it right. Also, lots of friends of mine love their products in real life, and the price was right so I figured why-the-heck-not go for it.These are the best bluetooth headphones out there that I have experienced. The wrap around back piece appeared a little too floppy in the videos, but it is more rigid than I expected once I got my hands on it which is a plus. These stay in my ears pretty well. The retention rubber band piece across the back doesn't slide when sweaty doesn't budge whereas the one on my great Sony headphones would slip all the way to the back of the band, so these are even better in that regard. The bluetooth signal is reliable, battery life has not been an issue, the startup and shutdown sounds are pleasant (like a record spinning up and slowing down). Also, the charger cover is sturdy, and it uses a standard cover. The earpieces are big rubber one piece jobs (not a little earbud nub, but a cover that goes around the speaker and has an earbud branching off of it) which makes it easy to rotate them for optimal positioning. Sweat hasn't bothered these. As far as signal, these don't lose connection when I have the phone in my waist belt and them on my head while running, though sometimes they do when I turn my head to the side. This sounds lame, but I'm tall and there are many headphones that can't even maintain a connection when my head is straight. When my phone is not pressed up against my flesh, the signal is great. I can leave the room with these in my house and stay connected, and at the gym I can leave my phone in one place while getting water or using a machine some distance away without issue usually.My only real complaint with these is the controls. The controls are awkwardly placed. I have to scratch my ear to operate the buttons which are all crowded on the top of the right earpiece. I'm not sure why the controls weren't placed on the back or bottom of both earpieces. The sony's had track skip buttons and play on one earpiece bottom with volume on the other and power/lock on the back of one. It would also be nice if there was a track skip back button. However, while I'm bashing this one aspect of the controls, I have to commend Anker on the reliability of the controls for voice actions. I can reliably use voice dialing or control my music via voice by holding down the center button for a second or so. None of my other bluetooth headsets were as easy to do this on, and some (Blayz) totally omit that feature while costing more than these. It also helps that their instructions are very clear and well laid out, and they are probably the best headphone instructions I've seen.So there you have it, these are the best I've used. The combo of price, comfort, and usability is astonishing frankly compared to the other garbage on the market. If you are on the fence about buying your tenth set of bluetooth headphones, I wouldn't be any longer with these. They are the last type I'll buy. I'm already considering grabbing another pair so I can have a backup set in case anything ever happens to these.

These are the most extraordinary earbuds I have had to date! They are very comfortable, a perfect balance of sound range (base/treble), loudness, and quality- and they stay in my large oily ears without falling out! With the silly cord between the earbuds that most have- the weight and length typically cause the ear-buds to come out of your ear over time. I thought it would be great if all wireless bluetooth earbuds could "lose" the cord between the ear pieces, but Anker designed the cord to actually work to keep the earbuds in the ear (rather than pull them out)! I'm an engineer and will say that this design is incredible! A+++++ job!!Update: Battery life is about 5 hours on 3/4 volume. Not quite the 6 hours Anker notes, but far better than the six different brands I've owned/used before!Update: The Bluetooth signal is the strongest of any of the earbuds I've owned. The signal range is about 40' and has never dropped within that range. It also is less affected with objects in the way then any of my previous ear buds!Update: I have read other reviews complaining about the poor bass. The bass is not extremely heavy because the rubber buds are designed to fit at the surface of your ear-canal, not inside the ear canal as most other earbuds. This makes the earbuds much more comfortable over long periods of time. It's probably better from a health perspective as well!That said, make sure that the correct ear bud is in the correct ear (there are markings on the black rubber buds-for example, "LL means "left lobe" and the "RL" means right lobe for the right ear). You'll need to experiment whether the best fit with the small, medium, or large lobe earbud.Update: i've now had a chance to have a few conversations and opportunities to dictate to Siri using these. The microphone is much better than any of the previous ear buds I've used. Not perfect, but you'll be surprised how high the quality is- even with ambient noise outside. Your conversations are very clear with no crackling sounds!Conclusion: I have spent way too much $$ only to be moderately pleased at best (including a high-end model which I won't mention the brand- but let's just say LeBron James endorses them!). Purchase these- you will NOT be disappointed!
