Review on Stay Warm And Jam Out With Rotibox Bluetooth Beanie Hat: Perfect For Outdoor Sports And Xmas Gifts by Kimberly Jackson

The idea is excellent but the actual implementation not so great. The problem is that everyone has a different head size & a different space between their ears! :) I'm a "normal" 7.5" hat size and I am relatively thin. The hat fir fine (maybe a tiny bit on the small size but wearable) but the problem is (was, as I returned it) the 2 bluetooth speakers didn't cover my ears. If I put one speaker on one ear the other speaker would be on my cheekbone. If I centered the speakers neither one would be on my ear and the sound level would be greatly reduced and muffled. This hat must have been designed with a small person as the "model." It is made in China and Asian folks on average are a bit smaller in size then the average American so that might have something to do with it. I REALLY wanted to keep it but the speakers just didn't end up in the right place (I even tried rotating the hat 180 degrees, Too bad, I like the idea and the style and even the soundBy the way, I ALSO tried a different brand of BT hat from Ebay. That one fit over my ears just fine but the hat was just so bulky and ugly (it was a heavy rope knit with 2 layers of material, this was a thinner single layer) I didn't like it. I much preferred this one for style but unfortunately the speakers just weren't spaced properly. So now I am back to a set of bluetooth earmuffs but I would have preferred the hat.In a future version they should consider allowing the BT speakers room to "slide" to adjust to different ear spacing. I would rebuy in a second.
