If you’re looking to buy a new set of earbuds, you’ll want to check out The NuraLoop Smart Earbuds. These earbuds are truly intelligent with their app-based hearing test that adapts sound to your ears. The test is automatic and quick, finding imperfections in your hearing and correcting for them. This gives you a solid sound experience. Also, the buds can be both wireless and wired. That’s a convenient option in case you run out of batteries. And speaking of battery power, these smart headphones boast a respectable 16 hours of playtime in Bluetooth mode. That’s a few days worth of sound without a recharge. Finally, the over-ear design and inner buds provide double isolation and a more secure fit for wear during workouts or even just a brisk walk.
