These earbuds are very comfortable to wear, and block noise form outside on a certain extent. Modern look, L-shaped connector and tangle-free wire make it so much easier for everyday use.I purchased CX 300II as well, they are similar overall. But CX3.00 provide a much clearer voice and wider space sound, and never get tangled like CX300II(I hate that, have to untangle it every time), and wires are equal long left&right(CX300II is unequal long).The only thing I feel..
GREAT Sound. VERY comfortable. I upgraded from the Sennheiser CX300 II and I am very happy I did. The CX 3.00 has symmetrical length cords. The buds sit more low profile in the ear. And the sound is better.
