Where do I even start with the AKG K371. When you listen to these, it's like everything disappears, leaving nothing between you and the music. It's arguably the best closed back headphone that you can easily drive with mobile devices, like cell phones. The only closed-backs (headphones that don't leak sound everywhere) that are a significant improvement start at around 900 dollars, and you can only get the most out of them with a bulky amp, which cost a few hundred. For most people, this is as good as you'll ever need. And once you consider the price of around 150 dollars, it's arguably the best overall.Now the sound. Oh lord the sound. These are quite frankly, beyond words to describe. If you're going from crappy earbuds or even mid tier headphones like the ATH-M50, it feels like listening to your songs for the first time all over again. It feels like there's nothing between you and the music. As for the actual sound signature, it's one of the best tuned headphones period. The slight bump in the sub-bass adds a subtle but fun kick. The bass is impressively detailed and controlled. The mids are well balanced without being reduced into the shadow realm. And finally, the treble is detailed and fun but without being too bright. Overall, it's very detailed and the tuning is to die for. Soundstage is rather impressive, and although it's not quite the best in that regard, it's nonetheless great. Noise isolation is okay, not great but good enough. Imaging (left-right differentiation) is very solid.These headphones excel at pretty much whatever you throw at them. I listened to a mix of Pop, Hip-hop, classic rock, metal, classical, electronic, jazz, synth, you name it. It's not just a jack of all trades, it masters then all. Gaming with these is also pleasant. I played Minecraft and Team Fortress 2 with these, and you have a pretty easy time discerning the direction of in-game sounds.Finally we get to the overall physical build of the headphones. This is where the only real flaws show up. Some people online reported QC issues, but they seem to be resolved at this point, and indeed my pair is fine. The top of the headband has some soft plastic imitating leather. This is actually a good thing, since it feels like it probably won't start flaking off in a few years. The inside of the headband is some sort of padded silicone material, which should make it real easy to clean. The headband adjustment mechanism is odd. It combines the function of adjusting the headband and letting the earcups rotate inward for storage. It's a little more loose that I'd like, making it hard to get an exact position while holding it, but it holds in place flawlessly once on your head. Fortunately, there's an easily accessible screw once you remove a soft pad on the inside of the pivot, so tightening the whole thing is no problem. the bottom part of this mechanism is made of metal. The earcups are hit and miss. They're comfy leather, but can have trouble sealing, especially with glasses. Furthermore, AKG does not seem to offer replacements on their website. I've found that Shure SRH1540 earpads function as a suitable replacement, albeit an expensive one. But I could not perceive any difference in sound between different earpads, other than an improved seal using the Shure earpads. The included accessories are nice, including the drawstring carrying bag. The cable is slightly microphonic (noise gets transmitted through the cable when you touch it), but you don't notice it at all with music. The cables themselves though (you get three, none with mic, just a 1m, 3m, and coiled cable, with a screw-on 3.5mm to 1/4in adapter. Having detachable cables is a very nice touch.So despite all the minor issues with the build, you might wonder why I'm still rating it 5 stars. Well, it's because they just sound that good. I couldn't recommend these enough. And for 150 dollars, it's a no-brainer.
Rating: [5 of 5 Stars!]
