Apple has it's own certification. MFI standard. That's means the cable is tested to use safe with Apple devices. I don't see anything about this cable that it is qualified with this certification.
Apple devices only handles 2.1 A as far as I know. So 3.0 A won't show any difference in charging time.
If the cable isn't tested for this certification, your iDevice will show a message you use a not-tested cable.
Maybe some will blame me for this advice.. But for earbuds I use the Apple EarPods. I like them a lot.
Not the best sound in the world, best I like how they fit in my ears and the sound is good enough for me.
It is a good choice, it will get the Android Nougat update and the price is still very good.
Of course, it isn't the most up-to-date Phone, but for the price it is worth it.
I loved to play SA:MP a few years ago. Still see people playing it, but it isn't as huge as in that time.
Indeed, MTA is still updated, but haven't play it myself.
Indeed it is personal peference, but I will recommand the DT770. Especially if you use your headphone for long periode of time, it is by far the most comfortable headphone out there.
