I brought the original samsung s4 headphones. Comparing with the S1 headphones that comes default with GT 8.9:
- Sound is a lil bit better and deeper.
- Volume control, the flat cord and adjustable wire splitter (or pinner or whatever its called), is a plus.
Design wise, i like the S1 better. Its has a more raw look while the S4 has a round ballish outward look that is bit protruding out of the ears.
