Tenergy Bluetooth Beanie in Dark Blue

My Kids love these things. Sadly, the charging port on one of them broke, because the light does not respond immediately, leaving my boy to think it's not plugged in all the way. The opening in the back could be a little bigger to help get the device from the hat for washing. The sizes vary too much between colors, I ordered 3 different colors and each one fits differently.I have a small head (I wear a size 7 1/4 hat) The light blue color I got the hat was so small and so tightly woven that it squeezes my head, giving me a headache over time It does look a little goofy when the kids are wearing them, but they are happy with the fact that they can basically lay down and roll around while still hearing their music. As far as the microphone goes. Huge disappointment. I was looking forward to talking on the phone with relative comfort, since the comfort was not going to happen I was hoping the microphone would be the hat's saving grace. Sadly, the microphone was not exposed enough to pick up my voice and I was told I sounded like I was talking from under the bed. For listening to music though, my boys love it, and I am sure the sizing problem is case by case, like I said they all seem to be different sizes.

Great product but battery life is not long lasting always charging. Better if you have ear plugs for sound quality. Still i like them

The battery doesn't hold a charge long enough.

This has been excellent for the price! I listen to these when I work in the cooler at work, always syncs up nicely to my HTC One M7 and the loudness is fine even with the loud cooler fans running. Quality of sound isn't great but good enough to enjoy, about what you would expect @ this price. Also, the beanie was high quality and thick so it is actually quite warm! I get nice comments from co-workers all the time.Controls on the beanie are working as advertised. It works with the Amazon prime music app too.

Connected easily and sounded ok (not great, just ok), but the fabric tore after a few weeks and the headphone started falling out, we returned it.

This is my second Bluetooth beanie and I found the audio to be even better than the first. Tenergy also fixed a few of the issues I had with the first one I got, and now I'm much happier with the way it functions. Improved is: audio response range, the buttons are much easier to press, the Bluetooth range is bigger and no longer does a loud voice tell you "POWER ON" every time you turn it on. Instead it's a subtle boop noise which I much prefer. This beanie is a bit thicker and better insulated than the first too, it's not really a summer or all-season beanie, more of a winter/fall one. Anyways, onto the main part of the review...What I Like:-Wireless headphones actually sound surprisingly good-Beanie fits comfortably and is warm-Headphones are removable for washing the beanie-Headphones have a good mix of bass and treble-The bass actually has some omph-Does not cut out external noises like real headphones so is safe to wear while walking, or exercising or anything where external noise is important to hear-Acceptable battery lifeWhat I Don't Like:-The speaker unit on one side is larger than the other which makes it feel off balanceConclusion: I was pleasantly surprised that the audio from this headset was not only good, it was very good! So long as it is aligned properly with your ears (as long as the beanie part fits right), the audio actually sounds pretty great for most genres. There is a good mix of bass and treble and the bass actually has some omph to it without drowning out treble. The volume isn't super loud though and it is worth noting that this device does not cut out any external sounds like actual headphones so you will still hear everything in your surroundings. The beanie itself is comfortable enough - I mean it's a beanie, that seems a bit hard to get wrong. The fit is fine for me, but it's a personal thing so it's hard to say whether it'll fit for everyone. It was a little bit tight around the ears at first but after a day or two of wearing it I got used to it. If you are sensitive to pressure headaches maybe this is not the right fit for you, but otherwise I have a pretty standard head size and I like the way it fit. Overall I think these beanies are great because other people don't know you're wearing headphones so you can get away with wearing them in situations where it may be frowned upon normally.-DrekiTech

Product did not work, tried calling support and unable to enter phone number for a call

Bought as a Christmas gift and was informed the charger would not work straight out of the box. Had to find another way to charge it.
