    AKG K 701, Sennheiser HD650 or Beyerdynamic DT880?

    Just get the DT880 and worry about a headamp later. You may learn you don't need one (I do not use one with mine in most cases), but if you decide to get one, you will at least know what aspects to improve.   Don't place too much importance on what others think sounds the best. The DT880 is...

    AKG K 701, Sennheiser HD650 or Beyerdynamic DT880?

    The DT880 is well known as a classical and jazz headphone. It is reasonably efficient and has an almost resistive load to the amp, so it is very easy to drive and usually does not require a headamp. The 250 ohm version is the most versatile and will usually work in situations the 600 and 32 ohm...

    Is the headpone amp on AKG Hearo 999 good enough for my Sennheiser HD600?

    It's uninformed bunk like this that caused the HEARO 999 to fail in the marketplace. It was and is good enough to be used in mastering studios. It drives my K601 cans to perfection. This is an old thread, but if somebody finds a good HEARO 999 Audiosphere II system at a good price on the used...

    Alternative to Beyerdynamic DT880!

    The sound you want is from an AKG K601 as far as the lively mids and tight bass would go, but it will bring your iPod amp to its knees. A less refined sound would be one of the Grado cans in the lower price ranges, SR60 to SR125. My Grado SR60 was very easy to drive, but from a top quality amp...

    AKG Q701 Review

    The K702 graph seems to have a slightly extended bass response just as the K601 would have if you overlaid them. Seems that maybe the K702 is a hybrid of the K701 and the K601. Bass response of the K601 married to the treble of the K701.   The K601 is the slightly warmer K701 that some...

    Three-way Review: K501 vs K601 vs K701

    The high impedance of the K601 was to help it integrate into a pro studio environment that had historically seen high impedance headphones. I remember that some of the early Sennheiser headphones were 2000 ohms impedance.   The K601 was obviously the fully open AKG design for the pro market...

    AKG K601 & K612 Pro Owners... UNITE!!

    K601 #5205 here. Also have a HEARO 999 #0253 and a no-number K301 XTRA.   Since I have two 999 headsets, I have the pleather earpads on one and the velour earpads on the other. With the pleather earpads the 999 leans toward the K601 sound, and with the velour earpads the 999 leans toward the...

    K701's smooth, lush and musical? Pure distortion... maybe, but who cares it sounds great!

    Yeah, music is a sensual experience......that's why a lot of folks went with the K601 instead of the K701. K701 was something different from the AKG house sound for audiophiles to fidget over, while music lovers who knew they liked AKG house sound went with a K601.   When the K601 is driven...

    AKG Hearo Wireless headphones

    I go the HEARO 999 deal with 2 headphones for $649 back in Dec 2007. I get wonderful sound and have had no problems, beside having to replace the batteries in both headsets. They had been in stock for quite a while and the batteries were deteriorated with 45 minute runtime. The Radio Shack...

    best wireless headphone system?

    The best wireless headphone setup was probably the AKG HEARO 999 Audiosphere II. That's quite a long name, and not easy to remember. I'll call it the 999 from here on out. I learned about them from a German audio engineer that uses them daily in his mastering studio. They were aimed for the pro...

    k601: a disappointment

    This MAY come as a bit of a surprise to many of you here, but a really good headphone amp that drives the K601 really well was made by AKG themselves. It only stands to reason that AKG would voice their amp to their headphones. You never hear audio reviewers mention it, but the amp was geared to...
