Like all products there are pros & cons, it’s really just a matter of what you can put up with con-wisePros:- The ability to use any wired headphones you want without getting your phone out.- Make ‘normal’ headphones into hands free headsets thanks to the built-in microphone.- Inexpensive compared to many wireless Bluetooth devices.Cons:- Reduced my iPhone’s battery life twice as quickly as a standard wireless headset- Sound slightly out of sync on Amazon video which is usually fine (I appreciate this is not an issue if just using for audio)The Cons are too much for me to be able to give a good review. I watch movies regularly during my commute & the out of sync dialogue ruins it for me. Then there is the ridiculous energy consumption which for a Bluetooth device is unusual but with an iPhone’s already hard-pressed battery is pretty much a deal-breaker. Expect to have to carry around a spare battery pack (if you don’t already) if you plan to use this.I do want to like this product but it just isn’t refined enough to take on wireless headsets just yet.
