Very bad sound. I can't believe AKG made it. I bought the headphones in Serbia. The sound is very quiet without bass and treble. In short, it's a joke for AKG.
These are studio headphones, so don’t expect to have the bass and kick drum pounding in your ears. That’s not whar these are made for. These are great for monitoring, mixing, and even recording. Semi-open, so while they have some external sound bleed, they do not give you ear fatigue from hours of listening.
These are durable, too. Probably because they’re so lightweight. They certainly won’t break under their own weight.
These are the most comfortable headphones I’ve ever had on for hours and hours.
They come with 2 different types of ear pads and 2 different types of cables. Those should be the only parts you ever need to replace. I’ve been using these every day for over 3 years and I’m still on the original ear pads and cables that came with them.
Be sure to buy from an authorized AKG dealer. I’m seeing a lot of knock-offs being sold online!!
I did burn-in for 20 hours before using this headphones for listening music, hearing foreign language. Pros: balanced, flat and no color sound. Mid sound is very clear (best for acoustic, live music and listening foreign language), high is comfortable, low is just enough. I can use for several hours without ear fatigue or feeling uncomfortable. Cons: It's better for being used as the studio monitor haedphones than for listening music but I can use it for both usage.
