Why does my earpods sound better with laptop?

Why? The laptop gives more bass and a better sound than my ipod touch 5 gen. I just bought my ipod touch 5 and its not fake and the jack also don't have a problem! I checked the earpods with the iphone 5 also the sound is the same as my ipod touch 5
so tell me any reasons shoudnt the ipod give more good quality sounds than laptops?
or because the laptops more powerful than an ipod touch?

Mobile devices are not designed to push enough power to make it sound better, they use very low quality parts and low power parts. Laptops are more powerful and push more power through the audio card.

It might be your laptop has actually got a better than average sound card, or there's some sound enhancement/equalization turned on. Ipods in general have excellent sound quality compared to cheap unbranded mp3 players as the reviews will tell you. The quality however is always dependent on the bit-rate of the file you are listening to.
