## Questions & Answers

**Q: are these compatible with iphones (5 or 6) and samsung galaxy phones?**
A: These are true studio monitor headphones! They have no inline controls and a long, straight, somewhat heavy cable with a heavy metal 1/4" phono connector. So, although they will work with ANY phone, they are not the best suited to portable use. They don't fold up and you'll need an adapter to plug them into your phone (they don't come with one, or anything else for that matter). They also have fairly flat frequency response; for most people this is experienced as cold, "sterile" sound with not enough bass! If you are set on these, might I suggest the MDR-7506 model. They are almost identical physically, but fold up, have a coiled (but still heavy) cord and a "warmer" more pleasing sound. They also come with an integrated mini phone adapter (just unscrew the 1/4" connector!) Still, not the most portable and no inline controls, but you'll save some money and probably like them better.

**Q: Is it possible that after 10-hour flight bass become weaker? Thank you.**
A: Weaker? No. I have owned 3 pairs in my life over the last 2 decades. Highly doubt this will happen in a 10 hour time period but over time, the pads can flatten and therefore the drive becomes just a half-millimeter to one millimeter closer to your ear causing it to sound like there is less bass and more prominent mids and highs. I say this because when my pads deteriorate over time and I've bought new stock pads, It sounds like the highs become slightly recessed making it sound like there is more bass.

**Q: I'm looking for a case for these, can anyone give a reasonable recommendation?**
A: No

**Q: Are the legit ones Made in Japan?**
A: Yes
