As for the cable, Shure provides plenty of length: 64 inches to be exact. However, those who had a pair of SE310s might be disappointed to learn that the design is no longer modular. That is, you can't split the cable at the Y-junction in order to make a shortened length for a player clipped to a lapel or worn in a shirt pocket. This is a bit of a bummer, because the cord is quite heavy and tends to pull at the earpieces with the entire length hanging free.
That being said, we appreciate the thickness and flexibility of the cable of the SE315 as it speaks well to the headphones withstanding the test of time. Plus, the Y-junction and L-plug housings are extra-rugged, and Shure now reinforces the cord with Kevlar. Add to that a two-year warranty and the fact that the earpieces are user-detachable, and you have a setup that practically screams "durability."
As for extras, the SE315 earphones include the usual suspects. You get a soft-sided, zippered carrying case and an earwax-cleaning tool. Plus, there's Shure's standard fit kit with three sizes (S, M, L) of the flex and black foam sleeves, as well as one pair of triple-flange and one pair of universal-fit yellow foam sleeves.
Of course, sound quality is perhaps the chief concern for a pair of earphones costing a couple hundred dollars, and the SE315s are mostly impressive, though we couldn't help comparing them with our $80 Klipsch Image S4s during testing. While the Kilpsch earbuds provide excellent balance and stellar audio across all genres, the SE315s sound rather anemic by comparison, specifically for rock tracks. Tom Petty's "Refugee" had a slightly hollow quality with an overly forward midrange, and that seemed to carry over to punk rock and folk tracks as well.
That said, we enjoyed the audio quality while testing hip-hop and electronic tracks. Bass is deep and encompassing without being too overwhelming. And hi-hats and triangles come through crisply with a fair amount of sparkle. Still, for $200, we expect a pair of headphones that sound good for all music, since you can find that for around $100. It seems that you're paying more for design and durability in this case, so if you value that and listen to mostly hip-hop and electronic music, the Shure SE315 earphones could be a good fit.
