Summary: I am a production sound mixer and absolutely love these. It's important for me to hear only what I'm mixing and no external noise or any "enhanced" frequencies that aren't going to the recorder.
These sound very transparent and do a great job at sealing out external noise.
My favorite attachments are the round, gray rubber ear molds. They have the best noise cancellation to comfort ratio.
Love the "over the ear design" for the cable.
Summary: If your an audio enthusiast that only demands the highest quality of audio sound, you will definitely love the Shure SE420 Earphones. At around 220 euros, most people might think money waisted, but for the audiophile its money well spent because of its high end luxury design and awe inspring sound that it produces.
Pros: Excellent audio reproduction, high end quality design
Summary: These earphones were to replace an old pair of Shure earphones that I left by mistake on an airplane. I had been looking at other makes, but knew what to expect with Shure. I can wear these for hours without them falling out or making my ears ache and the sound isolation is so good that I can just wear them as earplugs without anything playing through them if i need too. The sound quality is very good.
Summary: By any measure, these are expensive headphones, but they do sound incredible, with a very full, clear, concise and immediately responsive sound, and great sound isolation. In case you're worried, let me say now that you can definitely hear the difference in quality - they're unlike anything I'd heard before, including my old Shure 210s, which are already streets ahead of your average earbud or high-street in-ear headphones.
Summary: After unpacking the ear phone I had to choose the right sleeves. Not easy, because there were 7 different ones. I started with the medium soft foam sleeves. Not the right choice, but it worked. After a few days I tried the small ones and it was a fit. Not just better in my ear, but the sound was also much better. Used on my iPod touch it does sound better than the original Apple earphone, but used in combination with my CD disk player, a whole new (musical) world opened.
Summary: I have been with Shure for some time now. Initially started with the SE110, which was without doubt an amazing upgrade from the Sony earphones I had. When I first played music through the SE110 I remember feeling my hair raise, they were leaps ahead of the Sony's, and provided clarity I was not expecting, and did not even know could be achievable using earphones. This being said, my story with the SE110 was cut short when I lost them.
Summary: After some 12 months of playing iTUNES on a 80gB iPOD Classic with a cheaper headset I took delivery of these today. I have to say at the £159 Amazon are turning them out for they are a steal. Defined and deep in the bass, rich and detailed in the middle and smooth in the treble this really is iTUNES getting closer to hi-fidelity. Us audiophiles are a fussy bunch to please and our frequent complaint is of lesser quality equipment quickly becoming tiring and overbearing.
