The majority can't be wrong? Are you kidding me?
If a car manufacturer sells 5 million cars and 100,000 cars have a problem with the brakes but the rest are fine I am guessing you would have no problem travelling in it with your family. The majority can't be wrong can they?

So not going to genuine.

£2.99 from China

How do you know eBay ones are genuine

How do these compare to the Xiaomi Piston ones?

Mines turned up and have to say the quality is the same as the black pair I had ordered previously from amazon, so they seem legit to me.

Please check the negative feedback of the seller...there were quite a lots of negative feedback for for seller specifically relating to the "Skullcandy Ink'd 2.0 Supreme Sound With Mic Earphones" that he sell with mainly complains of mic doesn't work that these might be fake.

works fine for me, he also has a lot of positive comments about the same headphones, so make a decision instead of posting smear?

Where is the smear?
