Audioholics posted an interesting article on loudspeaker sensitivity specifications and measurements recently: http://www.audioholics.com/education/loudspeaker-basics/loudspeaker-sensitivity

 

They recommend using an averaged sweep from 300Hz to 3kHz (same as the National Research Council of Canada).

 

I wonder what other headphone manufacturers do for their numbers...

 

Yeah, that's more or less how I would do this for speakers.  Headphones are different, though.  I'll do my homework to do it right and when I can will post a result.  But for SWAG purposes assume 93-94 dB/mW.

Now it wouldn't be any problem to get the Mad Dog headphones and return them if they disappointed but I'm not in the US so I don't have that option, which is why I am a bit worried that it might disappoint since I do like some bass impact.

Anyone that have owned both and that would care to comment?

Thanks!

I feel the same way as Gelocks and the others mentioned too. The DT770 and D5000 definitely has more punch and oomph, but the MD's bass is more tight and clean and overall it does walk ALL OVER my DT770 80 ohm Beyers. I find the MD having more sibilance than my Beyer though, contrary to what is shared here. It is quite obvious. Is that just me?

Please correct me, Dan.

Skavoovie, Dan, I am not very familiar with headphone's power and sensitivities yet, but does that mean the amp should be recommended to be able to ouput more than 93 mW?

No, the power rating says "If I put 1 mW of power in, I get 93bB out."  The more efficient, the louder it will sound for the same power input.  

 

I recommended at least a solid 100mW for the Dog Pads, the Alpha really can be driven with 75mW or even less, if you're not cranking it too hard.

I'm about to be on a flight tomorrow... just to be sure, can I walk through security with the mad dogs hanging around my bneck?

By the way, the Audeze LCD-3 is rated at 93dB/mW.  My Mad Dogs track fairly closely.  Close enough that I'd guess that the Alpha Dogs are no more than 0.5dB more or less efficient (if using the same measurement technique/equipment that Audeze used).

post #3355 of 6388

So I just got a pair of Mad Dogs and these Alpha pads are even more comfortable than the pair I'd tried at a mini meet not long ago.  Sounds better than I remember as well, although that doesn't mean much.  

post #3356 of 6388

Thanks for some feedback on my question, not an easy decision so far on whether I should get a pair of Mad Dog Alpha or just get a new pair of DT770's.

 

Anyone here that have tried the Mad Dog headphones on hip hop/rap music? Or are they better for more instrumental and even accoustic music? I'd mostly use them for hip hop/rap and some trance, allthough what I listen to can be very all-round depending on what I am in the mood for and if I find something good.

 

Sorry if I am asking annoying questions but when returning them is not an option I really want to be as sure as possible that I'd like them if I do end up buying a pair.

 

Thanks again for previous answers and any answers to my new question! :)

If you're a basshead, then no.  They don't sound like subwoofers strapped to your head, but hip hop/rap that actually has a good amount of bass comes through cleanly.  I also listen to some hip hop/rap and it sounds good to me so far.  I'm not a basshead though so that's where I'm coming from.

Do you actually want to hear your music? Maddogs

OR do you want thick bass and have the high end squawk at you like an angry 12 year old? DT770 80ohms

 

No i am not really being serious, I am a Beyerfan too. So don't get all feisty with me. beyersmile.png

post #3359 of 6388

Hehe, I would say you hear the music quite well in the Beyers too! :p

 

I wouldn't really consider myself a basshead, not in the way that some seem to only think there's bass if their jaws are shaking, but I have been disappointed before by too unnoticable bass. Before I got the DT770's I had a pair of Sennheiser PC350, and although they are in a different league they are still decent headphones, but the bass on them was just too weak. That's pretty much what I mean, I just don't want the bass to be so weak that you don't really notice it. I doubt the Mad Dog Alpha's are as bad as PC350's on bass impact but it would suck getting them and being completely disappointed by the bass.

Since I listen at very low volume levels and my ears are more sensitive to the mid-frequencies, a V-shaped signature from a pair of D5000 or DT770 tend to flatten out the overall sound.  With the Mad Dogs, at a similar volume level, all I hear is the mids unless the song has very little dynamic range.  This was most noticeable when I recently heard Robert Palmer's "Addicted to Love" from the 1989 "Addictions" Volume 1 CD.  To hear the bass or treble, I have to increase the volume level more than I would like to seek balance across the frequency spectrum.  

 

Headphones with a V-shaped signature act a bit like the "Loudness" feature on a stereo receiver to boost the bass and treble at low volumes.  

 

http://www.extron.com/company/article.aspx?id=loudnesscontrol_ts

 

"At the boundary of minimum audibility, perception of low frequencies and high frequencies requires a significant level boost as compared to the midrange frequencies."

 

To be fair, we are not talking about a huge increase in volume to seek a perceived balanced output, and for music with a very large dynamic range from a well-mastered orchestral piece, I have to turn up the volume with any headphones to hear most of the music.  Although I find myself turning up the volume for a quiet part with strings, and then adjusting the volume setting lower once the horn section crescendos.

 

It is the one thing I found I needed to adjust to when going from the D5000 to the Mad Dogs.
