Monster Beats by Dr Dre Headphones (Can Type)
I decided to get these headphones after seeing them on various gadget websites and seeing them on display in the shop.... OMG they are awesome!

I can't believe the audio quality I am getting out of my HD2... of course, I "knew" quality headphones were important for listening to music... I have never been too crazy about music/tunes except when I do my workout laps at the pool ... then, the underwater headphones are crap and don't seal properly...
So, I have been missing out. I thought the earphones that came with the HD2 were pretty good. I have never had a decent seal with the in ear type plugs without being uncomfortable... This was until I walked into the store and by some chance decided to try these cans which were on display... after having been wowed by the display set, I tested this on my HD2 and was SOLD immediately.... they are expensive at $300 to $350 but heck... you MUST try them! THey do fold and when folded, becomes a more "compact" package than BOSE's offering... but the bass on this with crystal clarity in the treble blows the BOSE I tried away IMHO...
The BEATS come with a nice case and cleaning cloth... it also has TWO interchangable cables. One standard red one and another black one with a mic on the cable and a simple remote. This cable lets you take calls by pressing a button on the mic. The same button functions as a play pause button also. Nothing more is offered but the addition of a mic is a surprise for cans of this quality! And very welcome indeed... it can take a lot of time to have to pull out the headphones, remove the full size headphones and then take a call.... the mic cable is black in color and come with gold plated plugs. Finally, both a HiFi plug adapter and an airline adapter are also included
Downside... these headphones require power... power to power those drivers and also to run the noise reduction electronics. If the juice (2 x AAA) runs out, you won't get sound. The batts should run for a long time though... I have been using these for a while and have even forgotten to turn them off many nights... still running strong on the original Duracell batts

I will be swapping these out with Eneloop AAA batts when these run out though.
I am really happy with these. The comfort level is amazing with ultra soft pads over each can. the build quality of the plastics could be better I think for $350 headphones... but I am still wowed each time I wear them. The noise reduction is great for airplane or train journeys too... if you want to hear what is going on around you to engage in conversation, just press a button on the right ear... this disengages the noise reduction and mutes the music and viola, all can be heard! Sweet!
Don't take my word for it, go try them out!
Oh... I also use SRS WOW which I installed on my HD2...
