Review on 🎧 ISOtunes Original Noise Isolating Bluetooth Earbuds: 26 dB Noise Reduction, 4 Hour Battery, OSHA Compliant by Mandy Tyrrell

Pretty good for the price. I work in a factory. So if you're working on small projects on the floor and sitting in one place for several hours, ordinary headphones won't do the job of adequately canceling outside noise. They (when using the standard noise-cancelling pads) work amazingly well and are definitely OSHA certified. also depends on the connected device) and you get a good 3-4 hours of battery life. They even come with a nice case that you can slip in your work bag and carry around, but it also fits perfectly in your pocket. The sound quality is also excellent. I would even call them studio quality. You can hear all the highs and lows that matter with reasonable clarity, and none of the "blurry" ones you can think of have excellent external noise cancellation. I can't give you exact numbers, but for those who sometimes spend 8 hours or more a day listening to music, they are of really good quality and offer a good listening experience. The only problem I have or could see is getting the cable out of them. This is a very small and nifty cable that exits the headphones at a 90 degree angle. It's nice to wear and use, but once they're in the case and ready to be encased I would stress caution and definitely not overtighten them. I use mine regularly and haven't had any problems, but I think it's worth looking into. Definitely recommend these headphones.
