These being 55 ohm models, can you really get by without a headphone amp? I'm coming from Grado SR80s which sound fine without an amp, imho. This is for personal use, no mixing or DJing. Probably using a laptop or my Cowon MP3 player usually.

Having regularly used these headphones for two years, I never used a headphone amp with them. I plug them in directly in everything from my studio mixer down to my tiny iPod nano. I've had nothing but loud, clear sound from these babies without any additional hardware.

I would say no, these babies have an increased capacity for sound but don't need the amplification. They can run well off an amplified source like turntables or a midi device, but are more than fine without. Best headphones i have ever purchased.

I don't think so! I don't use any amp and they are really good for mixing. I think that they are just perfect

Nope. I have a hifonics 1000rms and its jist perfect. So beat bet, get one good amp or 2 decent ones for those subs. But i omly have one and people hear me a few blocks out.

This question highly depends on your headphone amplifier. The bass response is awesome with a proper headphone amp. For electronic music get a solid state amp.

I've used the amp maybe a dozen times since I got the headphones a year ago. It enhances the experience, but the headphones are already so good that I almost never use the amps. I would say the amp definintely isn't necessary.

Hey G M, I don't own any headphones over 60 ohm. So, I can't provide an accurate answer. Sorry about that. If I had to guess I would say this amp would drive your headphones nicely. Also, you have to consider the Source/DAC that you will be connecting to this amp as that will make a difference in quality.

that would be best way to get the most out of them but no you do not need an amp i have mine running off the mb quart 1000.4 there getting about 75 watts each set and man they sound great.

That aaaaall depends on your production/genre of music. I don't need them making all sorts of Electronic Dance Music. But I've heard adding a sub makes the sonic range even sweeter in the lowest end. If I had the cash...m'yeah...I'd get the sub, but for now as an intermediate producer, I can happily do without. PS. I bought these instead of the HS50 or HS60 because indeed, those models were bass-poor and only designed for rock, organic jazz or symphony production.

Yes, they can be used without an amp, but they sound much better in my opinion with one. Even a cheap Fiio E6 or whatnot. If you're listening out of a computer a DAC/amp like the Fiio E10 or the Fiio E7 or its successor, the E7k "Andes". I wouldn't say I'm an audiophile either and I used to be ambivalent about amps and DAC's until I actually tried them. Then I realized how good they could make a good set of headphones sound.

I find them to be very effecient. I dont mix or record but used with 1) My HP Computer 2) Pioneer Elite Reciever or 3) Marantz 8004 SACD Player all have rich full bodied sound at reasonable volume levels. In my opinion a heaphone amp may improve your overall experience but is not necessary in most uses. Try the without the Amp first you can always add one later if needed.

These will do okay without an amp on mp3/phone, you might have to consider buying portable amp to these headphones to their actual potential.

I use my P7 with an iphone 4 and the FiiO E11. Without the Amp is fine but I will say with my FiiO E11, the sound is better (not as loud) and the Bass is perfect and not overpowering. I did not expect this, like Johnny wrote, "They are very low impedance @ 22ohms." I expected the bass to increase but the sound is better as well.

So the resistance (Ohms of the headphones) tells you how easy it is to drive the speakers (produce sound). A higher ohms indicates that it is harder to drive the speakers; that being said that higher ohms means that the sound quality is better because there is less garbling of the signal. 30 ohms is standard and is appropriate for basically anything (mp3 players included) the 80 ohm can work with mp3 players but should have a amplifier, the 250 basically is useless without a good amp... if you want to get an amplifier I recommend the Fiio E11 portable amp (approximately 70 USD). Even if you get the 30 ohms DT 770 I am sure you will like it; I recommend getting an amp and higher "ohmage" if you want your music to sound just a bit nicer

The Patient is right. I had Grado SR80i cans hooked up to my computer without an amp. I played "White Noise" by Mogwai in 256kbps mp3 and at 1025kbps FLAC. The difference is incredible. I did this to illustrate the value of good cans to my room mate and he is convinced. I plan on getting the 555s as soon as I can, just to compare the Grado and Sennheiser sounds. You won't be disappointed with these if you play high quality files. Also, invest in cds of your favorite groups. That way, you can rip the cd at WAV or FLAC using a (free) program like Exact Audio Copy.

You *can* run them off of your laptop, but they won't sound very good. You will need some kind of amplifier. Fiio makes some good amps for the money. I would suggest something in the $40 to $100 range. You won't be dissapointed though, these headphones are awesome.

I disagree completely with all the comments above.I think people have a wrong perception of headphones quality. I am a basshead myself. The Q701 are perfect to restitute ANY frequency! I love listening to Kendrick Lamar for instance with them and the infra bass are making my head vibrate... But you will need an amp, that's all.
