What is the recommended impedance for headphones with this amp?

this amp distorted quite a bit with 60 ohm AKG 702 headphones at only medium high volume. this is all i know. there was allot of treble and base produced at all times by this amp.

Yes definitely. M50 has an impedance of 38 ohm but those "unprofessional" music output are mostly designed for earphones less than 32 ohm (preferably 16 ohm). If you're using a DAP such as DX90 instead of an iPod for M50, you'll notice that the player has better control of the music, more detail, bouncy and more punchy but at the sometime precise bass (drums). This is my experience as I have the same equipment you have.

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.

I'm afraid I can't say exactly how that particular Sennheiser will sound, and it doesn't really make sense to ask. But, it is the best headphone amp for the money, probably for 3 Times the money, and there is nothing odd about the ohm rating of the Sennheiser, so it's worth the purchase.

If the sensitivity is above ~86 or so you should be OK. I am driving a pair of Sentry 100A which have a sensitivity of 92db. They make plenty of sound and sound quite good even without a good preamp (e.g. a smartphone input).

From what I read the amp is pretty good as well and could handle phones up to the HD650, which are 300 ohms I believe,. The DT 880s come in 32, 250 and 600 ohms models. So depending upon your model, the 600 Ohms would work, but would push the perfomance a bit. Some people with 600ohms headphones would still buy the Fostex for portability, and then might have a desktop amp at home. The opinion i gave is a uer's experience in the Head-Fi forum.

This little guy really shines as a headphone amp, but does well with speakers too. In your case, I'd be a bit worried about clipping since it's rated at about 17 watts @ 8ohm. No experience with lower impedances. If you're not set on a hybrid tube design, check out some of the dedicated solid state 2 channel stereo amps by Denon or Onkyo. My Onkyo does wonders with digital files with its built-in Wolfson DAC.

I have used a variety of low impedance ear buds (16 ohms to 60 ohms) with the E11 amp with very good success. The amount of improvement can be very subjective and will vary according to the playback (music) source you are using. All things being equal, devices having puny headphone-driving circuitry will sound better through use of the FiiO E11 than will higher-quality playback devices. Also, because the E11 has built-in switchable low frequency boost, many (though not all) bass-shy ear buds can be made to sound much better. One of the other posted answers to your question that I read suggests that headphone impedance is an indicator of sound quality. Not true. I'm an electronics and professional audio guy of many years. Headphone impedance is simply an electrical characteristic that needs to be matched to the headphone amplifier that drives the headphone for best sound quality. Some headphone amplifiers on the market can't drive high impedance (300 to 1,200 ohms or more) headphones. The FiiO E11 is rated to be used with 16 to 300 ohms headphones. I hope this answers your question. Best.

I use my amp with 2 sets of phones. Both are Beyer-Dynamic at 250ohms each. One open back, one closed back. The sound is great, I think you will be pleased, especially with Sennheiser open back phones.

The 6 Ohm setting on the amp should work okay for your nice 8 Ohm speakers. Higher impedance speakers should dissipate less power and consequently might sound a tiny bit quieter than lower impedance speakers at the same volume setting. But I doubt you will notice any difference.

The impedance depends on whether you have had 1, 2, 3 or more than 4 drinks. It is actually the same answer for what is the acceptable volume for these speakers. They sound great. You need to invest in a sub-woofer to full appreciate them however.

You will get maximum output when the impedance of the headset matches the output impedance of the device. My Samsung phone is rated 32 ohms output impedance (measured at 35 ohms published on jensign.com), so a 32 ohm headset would be the best match. If your headphones had zero impedance, you would not hear a thing. Bobbyjo and T. Smith answers are both misleading. Matching impedance is best.

I've heard it ranges from 15Hz to 28kHz. I would recommend a headphone amplifier if you want to enhance the lows. They are definitely comfortable and provide pretty good passive sound cancellation.

It should. I typically wouldn't use a headphone Amp until 65 Ohm or greater.

Yes you really only need an amp with high resist and low sensitivity headphones. This has pretty low resist and the sensitivity is high enough to be really loud at 50% volume on a ipod.

Not my Sennheiser 650 s. I have to go. Phono -&gt; Ballari -&gt; 6922EH Tube Headphone amp.

Short answer to that question, is HELL YEAH. This amp should be able to push your headphones to their max potential, I looked up your headphones and they're rated at 32ohms impedance, I run a pair of Sony MDR X10 that are rated at 24 ohms, so mine have a slightly less load than your headset will put on the amplifier and mine are very loud with this amp. The amp is rated up to 100 ohms on the highest gain setting, so I think it should be more than sufficient to push your headphones closer to their intended limits, almost 2 times better than your iPod or equivalent listening device can manage. Do it! I wanna see your review when you've tried it. P.S. if you like to listen loud for a long time the battery in the amp won't last very long, I haven't timed it, but on high volume levels I might have gotten closer to an hour before getting the low battery light, Its a blast though. Good luck...
