  1. Tempest V

    This product is a joke. I’ve used real bone conduction headsets, and they aren’t anything like this hat. The speakers on the hat are just that- regular old speakers. Whereas the real bone conduction headsets don’t make noise when they aren’t on your head, and can be turned to decent volume without being heard by others, the speakers on the hat can be heard quite clearly sitting in your lap, and if you turn up the music loud enough to be heard, everyone else in the room is hearing it too. They are no different than headphones, except that they aren’t directly over your ears, so you need considerable volume to be able to hear anything out of them.Build quality is abysmal. The speakers are attached to the sweatband of the hat via a magnet that sticks to the back of the speaker. One of the speakers slipped off the sweatband, and while trying to peel the magnet off to reattach it, I thought the speaker was going to split in half before the two magnets separated. It is clearly not built to last. The wires running from the brain box under the brim of the hat to the speakers are kept in place via double sided scotch tape. The hat is of very light duty manufacture. That’s not a big deal if it’s a cheap hat that you replace often. It doesn’t work when it’s a host to the electronics. Even if the electronic bits last a decent amount of time, if the hat rips, you can’t just buy a hat to replace it. The hat is also very ugly to boot.After seeing how horrible this hat was, I quickly went to my Amazon account to return it, and found that it could not be returned because the seller had marketed it as “flammable or explosive”, which makes the item unreturnable. Thankfully, I contacted Amazon customer service, they contacted the third party seller, and I got my money back.

    Ok. I have bought multiple units over the last 8 years. The best application is if you work at a factory and use earplugs. It’s this case this is the greatest investment you will ever make! It is discrete (get the black hat or put it in a hat of your own. (with no brim stitching) with earplugs in and proper contact with your head (not too much hair blocking) and proper hat fitting (good tightness/tension in your hat) and you will enjoy Siri/Google assist/music/podcasts/audiobooks/ phone calls….at work! This isn’t beats audio! But try wearing those suckers into your workplace. Had been truly life changing.
