These are going to be my first grado headphones.
Source is mostly a macbook and a galaxy S3. I dont want to spend more on an amp for now, these seem to be driven easily. I mostly listen to rock, indie, a lot of Radiohead, Thom Yorke (the eraser), Atoms for peace, etc. 
Is there any big difference between them? Which one should I buy?
Thanks in advice.

many people will tell you to just shell out the extra money for the 225i's. it's worth it.

The SR 80i was my first pair and I outgrew it pretty fast. I would say go for the 225is as there is a noticeable sound quality difference.
