AKG N40 Customizable High-Resolution In-Ear Headphones

Very revealing! Much better than the Monster Turbine Pro Copper it replaces, which were pretty good to start with.

I researched these before I bought them. Several reviews made the same observation: these in-ear headphones behave like "reference speakers," in that they faithfully reproduce the signal sent to them. When I first opened the box, I tried them out on my iPhone, and was disappointed with the sound. Then, I tried them on my high-end DAC with quality digital inputs. They are phenomenal when fed a high-quality signal. They do not cover up flaws in a low-quality signal, but allow whatever detail (good or bad) that's there to come through. Since I bought these to use with my main system, they are great--exceeding my expectations for that purpose. I'll use my less expensive buds when listening on my iPhone or iPod. Ergonomics are fine. The bodies fit nicely into the outer ear and the stiff cord loops nicely over the top of the ear. I replaced the standard baffles with the base ones. It was very easy to do. There is not a lot of additional base response, but enough to make it worth the change.

has awesome sound!! i prefer to oppo pm3. you need amp to get the best from them.

Just beautiful sound, straight out of an iphone 6s it is already better than any other earphones I've ever tried (used in the range of 150-350usd). If hi res music is used like the files from Tidal, one starts feeling line there is actual music on one's ears instead of good sound. Instruments are separated, small details can be detected, voices are just incredible... I think it performs it's best on the mids but the low and high frequencies are still presented nicely with a nice amount of bass. I added a Audioquest Dragonfly Red and the earphones come even more alive, you gotta be prepared to that because you will be rather impacted if you are used to less quality. It's pretty much a new level.Great fit, really excellent cable (not noisy) and the fact it can be changed is just essential, comes with an awesome presentation... all in all, couldn't ask for more.

Order received this morning. I just opened padded envelope and the box was 100% EMPTY!!!! Not a single thing inside the empty box, not even a manual! Very nice box but I didn't pay over $300 for an EMPTY BOX!!!! I am PISSED!
