I bought this for myself In the Early Fall. It was such a good deal that I couldn't pass it up. I didn't have high expectations for the price, but it ended up being a great accessory. A single charge lasts for a week or so with casual use, and, apart from the blinking light on the ear, nobody knows you're listening to music while it's on. If you're looking for a killer hat that will blast some killer music via Bluetooth wherever your head may need some warmth, this is your hat.
So! The beanie itself, it's nice and thick and feels fairly high quality. It's warm and snug on my head. The speakers sit about where they're supposed to be, and it feels super comfortable. Beanie quality is great. I have bought few of them fr my little nieces, they should be very happy with the gifts, I think :))
I received this earlier today and got a great opportunity to put it to the test. It was an abnormally cold day in VA for fall (windy and about 38º) so I took the dog for a walk. I took it out of the box, saw the instructions and immediately threw them aside. If i was to test this out I was going to do it blindly to also check the ease of use. I pressed and held the play button on the side until it chimed (it also makes the led on the patch blink blue) and then I went to the phone. Bluetooth picked it up and it connected very smoothly. I picked a podcast and hit play, it played perfectly.
It was time for the walk. I headed out with the dog and realized that the hat was perfectly warm for the moderate weather. the sound was loud enough to drown out traffic but probably will not work at all for snow blowing when it gets even colder. I tested the buttons and they all worked fantastically. I got back from the walk (15-20 minutes later) and realized I hadn't charged it yet so I grabbed the micro-USB cable it came with and plugged it in. It took maybe another 15-20 minutes to charge up and was ready to go with a full battery. I can't attest to the quality of the battery life or the use of the microphone yet but if they are as spot on and flawless as the rest on the product them I am sure they are dead on. Obviously, the battery life can be affected by the volume and not properly turning the headphones off when done but it will more than suffice for my needs.
This hat looks beautiful, feels comfortable, and works with my phone. Highly recommended.
