SAVFY V4.1 Bluetooth Headphones Wireless Sport Earbuds Sweatproof in Ear Stereo Earphones for Running with Built-in Mic, Black

These things are surprisingly great! The sound quality is on par with my $130 sennheiser wired ear buds! It's amazing these are sub $20 but work wonders.I docked a star because-The ear buds don't fit perfectly in my ear. Maybe a double flange would work better for fitting than a single flange?-The "battery low" warning is WAY too late. You get maybe one song left once this warning comes on. Being at the gym and starting your set, only to realize it's been a few days since you charged is a serious buzzkill!But I'm really just nitpicking.

Good

**I received this product for free in exchange for an honest and unbiased review.**Much more comfortable than I expected. I thought it'll be too tight since the loop around ear is not adjustable but after wearing for an hour or so, I didn't really feel like it is there. Took me a while to put it on comfortably though but after that, it feels nice. The sound quality is pretty good also, very clear, couldn't hear much background noises. Pairing was fast, only took one try. This give you great mobility, doesn't have a long cord that tangles when you walk the dog, do things around house. It sits around neck when not in used, doesn't fall when only one ear piece is in used. Great little pair of headphones.

These are my first pair of wireless headphones. For the price they work great! They communicate flawlessly with my phones.They take a little getting used to - as they fit snugly and block most external noise. I found this good for using them while working or exercising.The string connecting L and R is the right length.

Love these! Wish I could find another pair

This item was returned as soon as opened the package. It did not work and the quality is poor.

There's an old saying, "You can't get there from here." Devices like this can't match the level of performance of a wired set at the same dollar. It's an exercise in working against yourself at every turn. It's nearly physically impossible. Why? Because; Physics. Keeping this in mind and bringing a reasonable set of expectations to the table you leave with a surprisingly well performing product for a humble price. I'm not going to recount features or other information that's already covered but address my experience and observation - that is the reason they sent me a pair to evaluate after all. The good: Long run time of at least 4 hours before charging, pairs easily, comfortably lightweight, very well featured. The bad: Poor clarity, high noise floor, limited frequency response, potentially difficult to operate features due to limited controls. The takeaway: If you're looking at a product like this you are going to have to accept compromises. Argue all you want but some things are literal facts. This set of bluetooth earphones suffers from the same constraints any other device of this type is going to be plagued with. It was however comfortable for use for several hours at a time. It was not any more difficult to operate than any similar device I've used. The sound was more than acceptable for where it is intended to be used and was fairly surprising for media purposes. Who should buy this? Inner city commuters, people on the move, those who frequent the gym, anyone more concerned with portability and features over performance. And for those individuals, this offers a very well balanced set of features at a very attractive and affordable price. Product was provided for purpose of review.
