Rated 5 out of 5 stars
Amazing Headphones however...
These headphones were really good however i have a few things to add. If you are looking for quality, you got it right here. If looking for deep bass these might be lacking, don't get me wrong they still sound amazing with their level Bass yet I enjoy the most bass. So if you aren't looking for the best Bass level, or if you aren't a true Deep Bass lover as I am then you shall be stunned by the quality of sound. Quick Recommendation if you are looking for more bass with good quality look into the B&W P5, they sound amazing and even have VERY STRONG BASS which is ironic because you wouldn't expect it because of their size. However the P5 are not Active noise cancelling but noise isolating (still 60% as good due to the design). If looking for better Active Noise Cancelling look into Bose QuietComfort 15. They do have the best noise cancelling. However they do fit a bit big so if size is important look into QuietComfort 3. Again the AKG are the perfect level between Deep Bass, Noise Cancelling, Size, and Quality. If you enjoy one feature over the other then look into the above headphones.
I was looking to replace my Sennheisers but couldn't find them locally, so I looked into these headphones. They're great for sound design and the sound cancellation... well, my wife made me nearly jump out of my skin when she touched me on the shoulder, cause I didn't hear her come up behind me.
great audio quality - noise cancellation on or off
I had the small bose top of the line noise cancellation headphones for 10 years. They just stopped working so I looked into several replacement options. The AKG offered the best balance of sound quality, flexibility and overall quality. The beauty was the phones were on sale so I got an outstanding deal! Thanks BB...
