First I buy and test many different headphones and test them with two different iPhones (XR and 11 Pro). I have to say Apple has locked down its audio and is offering a much more subtle music experience with the iTunes controls. Android systems allow for much better software and tools that work with all types of audio at the base level of phones. Now let's get to my review. All of my test comparisons are measured against existing, store-bought standard Bose in-ear and noise-cancelling headphones, Sennheiser HD570, Philips SHB3060 and JBL Titanium in-ear headphones. It is highly recommended to use Sennheiser HD1 Free. Pros: They're solidly built and offer plenty of headphone adapters to fit your ears perfectly. The controls on the cable are clear and easy to use. The sound quality for music is the best we've tested so far. The bass is even and undistorted. (see my other reviews). High and mid frequencies are clean and crisp. The left/right separation is excellent. They're good for the gym, phone calls, and real audio listening (8/10). Cons: This is the last few years, seconds since Bluetooth 4.2, and the box has white self-adhesive labels covering the barcodes. Then why are they being sold as new? In-ear earbuds will never be as good as Bose's soft earbuds. No other manufacturer has succeeded in doing this. And those adapters are crucial for proper ear canal closure and bass response, as the headphones can't offer that much bass even with those tiny drivers. They are essentially very small near-field monitors. No additional programs or features (although not very necessary). I am sending them back as they are not new.
