I just ordered these on a Groupon promotion that lowered the price to $30 (which I couldn't pass up). I come from a Phonak PFE 012 so it's gonna be interesting how these compare to something 2x the price

Thanks guys, I'll definitely take all your suggestions into consideration.

This is a completely random question but, does anyone use leather conditioner on the earpads/headband? If so what do you guys use? Mine are still perfect, but I just want to take care of them in the long run. 

For some reason that concern doesn't sound very good for your ears... don't play so loud lol

The HD25's are indeed a favorite for many. In America, almost all ESPN sport analysts and other news stations use them. They are suppose to isolate noise extremely well which makes them very ideal for a DJ especially. The huge difference between the HD25 and the Amperiors are what the cups are...

Sorry, I can't say much about the amperiors since I don't own them. Only heard them once. In terms of soundstage I found the amperiors to be more narrow than the momentums. Sound wasn't as laid back as momentums but bass is very tight and highs more sparkly. In terms of what you want... you...

The amperiors have a much more aggressive sound than do the momentums. It won't be a downgrade just something different Sent from my C6602 using Tapatalk

I've had my Momentums for about 5 months now and every time I listen to them they amaze me. I came from the Bose QC15's which were my first real headphones in my opinion (was on the new skullcandy ink'd every 3 months before that) and the Momentums really opened me up to what good sound really...

1) Sennheiser Momentum 2) M-Audio Q40 3) Phonak Audeo PFE 012 4) Bose QC15 5) Sony MDR-NC22 ... last) apple earbuds lol

Uhh, actually I'm in the same boat as you. But at the moment I'm considering the Fiio E11, E12 Amps or E17 DAC. But I might stay unamped so I'm not sure what I'm gonna do.

The ZO2 has been discontinued unfortunately. But there is talk of a new ZO3 coming out soon. Sent from my C6602 using Tapatalk

Just walk into a Mercedes dealership and ask if they have the 2014 s class in the showroom. The burmeisster sound system in that thing is quite awesome... too bad it's waaayyyy out of my price range Sent from my C6602 using Tapatalk

I've heard Bang and Olufsen and they can be very sparkly with nice punchy bass. So far my favorite is my M-Audio package that came with some older bmws. Harmon Kardon is a very solid option in my opinion also Sent from my C6602 using Tapatalk

Hey guys! I've been lurking these threads for a long time and just ordered the q40 because they seem to put out the amount of bass without sacrificing much. Coming from momentums what should I expect? Will be used mostly for EDM and bass heavy music Sent from my C6602 using Tapatalk 4

I got open box sennheiser momentums from razordog eBay and they were absolutely perfect and are still serving me well today. Sent from my C6602 using Tapatalk 4
