Summary: Do you want a grado? Are you on a budget? Do you live outside the usa? Get these.
I'm going to say it like it is.
Grados past the sr80i aren't worth it. The alessandro ms1 is essentially a sr125i for $99.
I own the grado sr225i (well they broke) and i put these to the test. Since the right cup on my grado sr225 is broken i swapped cups and listening with the alessandro ms1 on the right while the grado sr225 is on the left.
Summary: My first set of 'real' cans. It transformed my music library over just a few weeks. The texture and detail are the best I have heard for their price, and the best I have ever owned. While not good at electronic, acoustic, rock, and metal sounded fantastic.
I unfortunately killed a driver while performing my 900th mod. I miss them. Hopefully I will own them again one day.
Pros: Clarity and detail at its pricepoint. Moddibility.
Cons: Emphasized mid-bass. Small soundstage. Uncomfortable pads.
Summary: I wanted some tried and true entry level Hi-Fi quality headphones. Easy Answer: Grado.
I research and researched... Which ones to get? SR60i, SR80i, SR125i? Then I found out about Alessandro.
Alessandro MS1 was basically the SR125i sound, but for only $99.00. Perfect!
The first time I played these (even with no burn in) I knew I had made the right choice. CLEAR! So clear with a wonderful mid bass bump. I heard things in songs I never knew were there.
Summary: These where my first good full-sized headphones and have served as my main headphones for home use since 2007 until recently (2013).
At $100 these are a good price, especially for people living outside of the US where Grados are just way too expensive. The sound is relatively flat, but the mid-bass is a little emphasized. Some might call that "fun" or "punchy", but I could live without it, honestly.
Pros: Very good all-rounder, excellent value for the money
Cons: Tiny soundstage, can become uncomfortable after a while, mid-bass hump, leak a lot, not really suited for portable use.
