Sennheiser Hd600 Headphone Amplifier

At this price there's no other headphone that can match the Hd600's. They are about as neutral as you can get in this price range. Bass is tight but not boomy. The mids are airy and open. They are quite comfortable too.

I finally replaced my 11-year old AKG K 701 headphones with something newer - the Sennheiser HD600's. Actually, the HD600's hit the market before the now-discontinued K 701's but they appear to be a timeless design that still finds favor with studio pros and music lovers alike. I needed the higher impedance (300 ohms) of the HD600's as compared to the newer AKG K 712's - the replacement for the K 701's. The higher input impedance of the HD600's are a better match for my headphone amp which has a relatively high output impedance of 10 ohms. If you don't have a roughly 10-to-1 difference between the output and input impedance your system it could create some severe frequency response irregularities. I was hearing this with my old K 701's driven by my new headphone amp. The HD600's solve the problem, sound great and are very comfortable. I just hope they last as long as the AKG's...

The HD600 is a classic headphone, and it still holds its own against contenders in its price range. In my opinion, it is better than the headphones in its price range. To elaborate, perhaps the biggest contender in the HD600 price range now is the Hifiman HE-400. The HE-400 has a meatier, faster bass that extends deeper than the HD600. However, the HE-400 can't even think about touching the HD600's mids. The HE-400's biggest weakness is its mids presentation; the HD600's biggest strength is its mids presentation. And again, in the highs, the HD600 far surpasses the HE-400. The HE-400 has recessed lower highs, followed by a crazy peak in the upper highs. The HD600 is much more evenhanded, very smooth, nonfatiguing, and yet still detailed. As for the soundstage, the HE-400's is wider, more panoramic. The HD600's has a more realistic shape and depth, however. Both are nice, but the HD600's soundstage is more natural ultimately. To summarize this brief comparison of two of the mid-fi heavyweights at this time, the HE-400 does one thing really well, and that's bass. If all you care about is bass...well then the HE-400 is snazzy. If you want the whole package, the HD600 is it. It's on the smooth side, and sometimes lacks aggression; but it is a very good, natural sounding headphone with fantastic mids / vocals that are best in class. Highly recommended.

SENNHEISER HD600 are a great addition to my ONKYO portable audio player. Playing FLAC AUDIO files is a joy as the headphones bring out the best in audio.

I've been through many cans in the past, from the Sennheiser's HD600/650/700, also, the Audeze LCD-2 and a few others. I've been after the perfect sound, not the most accurate in terms of reference sound, but the most enjoying when it comes to kicking it back and listening to my tunes. After trying the Sony MDR-1000x wireless, I found the sony sound signature very pleasing, and just right for enjoying your music library instead of mastering or mixing audio. So, I decided to try the MDR-Z1R's and WOW! What a joy, a joy that comes with a very steep price; I bought the USA version and I don't regret a bit. These have the best Bass response ever, very well controlled unlike the Z7's also, they don't slouch when it comes to the Mids and Treble. If you're after the BEST closed headphones for enjoying your music, look no further

I bought the Rolls Headphone Amplifier to allow several people to simultaneously monitor an audio feed and it has worked well. A power-cube is included for use when a power outlet is available, however I am using it in the Field so the 9v battery which can power it allows me to use the Rolls Amplifier anywhere. I am pleased with the rugged metal construction and the simple power switch and individual level controls, the Rolls sounds wonderful and I have tested it with several different portable Recorders and Headphones and I am quite pleased and would certainly purchase it again and can recommend it wholeheartedly.

This is probably the best solution for a portable, pro headphone amplifier at the $ price point. What sold me about this unit was its wide range of input configurations and the fact that it does have both size headphone output jacks, which is perfect for working with clients who have their own headphones but not the adapter. These amps have plenty of clean, quiet gain. More than you will need and enough to blow up cans. It doesn't have an input trim so you ought to have some gain control at your source output. Your best bet is to run signal into this thing at unity gain. It is built very well and has a solid, steel chassis. Built in the USA, too.All in all a great piece of equipment that will save the day for only $

I am using this headphone amplifier as a distribution amplifier to route audio to a couple of devices and it is working great. I like the fact that each output has its own audio adjustment.

It's a great headphone amplifier, but what's also nice is it has one output for monitor speakers, with a volume knob control. We send this to the powered speakers in our school's edit lab, making it very easy to adjust volume independently to the headphones or the speakers at our Instructor station iMac.
