gretax's Full Review: Grado SR-125 Professional Headphones
It's a given that Grado cans, while not "street stylish" or hip in the looks department, offer the very best in price/performance and cost-effectiveness, especially in the $60 - $200 range.
Basically, the standard one should use when selecting between Grado cans is "how good is my equipment?"
Case in point: along with these SR-125, I own a pair of Grado SR-225s. Mostly, I use them on my cheap, 1990-ish JVC boombox (it's the closest CD player to my desk).
I also use them with "better" component systems located around the house, BUT if I were only using them on that boombox, the extra $50 between the 125s and the 225s would not, in my opinion, be justified. It would make a difference, but of such minuscule significance that the purchase would not be justified.
If, however, you are running a more audiophile-grade component system, the extra cost would be justified and real aural benefits would be reaped. If you have "better" components (or are planning on getting a good headphone amp, especially the Grado RA-1), buy the best set of cans you...well...can! The cost will be justified (for more on this, see my <a href= http://www.epinions.com/elec-review-3ED3-3A045A4-3A245CAC-prod1 >Grado SR-225 review</a>).
As far as the particulars on these cans go, I found them to be a nice "step up" from the 80s. They have even more bass, however, they seem to "overwhelm" themselves sometimes with it. I don't entirely like that and that is one of my main reasons for getting the 225s.
The SR-125's UHPLC copper (Ultra-high Purity, Long Crystal Copper) voice coil wire made a noticeable sonic difference to me up from the 80s, but again that bass sometimes takes over too much, to the point where it is distracting.
Supposedly, the earphone diaphragms are put through a de-stressing process as well, and I'm sure that made up a part of the audible difference between the 80s and the 125s. The bass, midrange and treble are wider and the soundstage is improved to a good degree over the 80s.
At the end of the day, your first consideration is what you can afford, second is what components of what quality do you have. This will, in the grand scheme of things, get you what's best for you.
