    HA43 - 4 Output Stereo Headphone Amplifier is rated 4.6 out of 5 by 35.
    Rated 5 out of 5 by from great product This is a very well made unit, and can have variety of uses. I currently use it with my HDTV so that several people can watch TV wearing their headsets without disturbing others. The sound quality is top notch and the build quality is also excellent. Please note that they make two different versions of this thing. Make sure that you're getting the Pro version, which is what sold by B&H here. Some other vendors sell a similar unit but is not the Pro version. The difference is that the Pro version has both 1/4 and 1/8 (3.5mm) jacks for each channel, while the non-pro version only has 1/8 (3.5mm); and also the Pro version has both 1/4 and RCA jacks for input, while the non-pro version has only 1/4 not RCA.

    Rated 5 out of 5 by from Superb quality for my Xbox 360 First off,this amp is POWERFUL. I have to watch my younger cousins to make sure they don't deafen themselves with their own headphones. Second, the quality is very sharp and clear, much better than the other options that exist for headphones for consoles. Third, I can share the amp with 3 other people, they can finally appreciate playing first person with surround sound. I have it connected directly to the output from the a/v cables of the 360, I didn't have to deal with any optical cable hassle. This is the easiest and best solution I've found to surround sound headphones for gaming. I can't play without them.

    Rated 5 out of 5 by from Works exactly as advertised We have a high end A/V receiver with only one headphone jack, and two sets of headphes with different impedance levels. Using a passive splitter resulted in one set of headphones being much louder than the other. This amp is the perfect solution. Small (important in an apartment), does the job with no perceptable difference in audio quality, and way less expensive than comparable units. I also like that the output jacks are in front. Makes connecting and disconnecting headphones easy. We mainly use the unit for home theater after our little one has gone to bed, so we can enjoy movies and TV without waking her. The only negative, and this is purely subjective, is that I'd prefer knobs to sliders, but it's a minor quibble. Highly recommended.

    Rated 5 out of 5 by from Solid, slick, smooth, and super sound Remarkable nowadays is the solid metal construction of a pro-level audio device for under $50. Things just keep getting better when one begins plugging in cables and finds the versatility of high-quality jacks for both 1/4-inch phone plugs and mini plugs. Equally impressive is the smooth operation of the gain controls, with the mid-point detent as a handy reference point, so it's not necessary to look at the unit when adjusting gain. Most important, the output is superb--nothing added, nothing taken away, just 20db of gain without any distortion.

    Rated 5 out of 5 by from Nice small headphone amp Rolls makes good stuff, so I always try to buy it. This one is no different. I needed a headphone amp to split a line for some musicians so they could hear a click track in rehearsal. I picked this up and it worked really well. They could each adjust their own volume. I've had problems with other headphone amps not having stereo outputs, which is a big problem. This one is stereo, and works really well, sounds good, and has a nice clean look to it.

    Rated 4 out of 5 by from Rolls - a solid contender I bought this as part of a small mobile recording unit I need on occasion for some podcasting production I do. As with all other Rolls products, this little headphone amp is really sturdy, and it's simple plug-and-play. It does not impart either noise or color to the sound received in the headphones. Probably my only gripe with this is the necessity of a wall-wart power source. Other than that it's perfect for many applications.

    Rated 4 out of 5 by from Works like a charm, Sounds great Bought this in an emergency to provide remote headphone monitoring for Director, & DP at a small video shoot and couldn't justify the cost of Pro quality Sound Design or PSC units. Sound quality was excellent though probably not what you would want to use for critical monitoring or mixing situations. Gain was impressive, be careful with the volume if you value your hearing. The short throw faders have a detent at about halfway. Outputs have dual 1/4 & 1/8 TRS jacks at each channel, 1/4 TRS and RCA in. Rugged steel case is compact, fine for tabletop use but probably not in the mixer bag. The only feature really missing is optional battery power. I have a new cord on the way to feed it off of my NP-1 brick if necessary.

    Rated 5 out of 5 by from Rolls HA43 (Pro) - This goes to 11! There are two Rolls HA43 amps: The regular, and the Pro which is what this review is for. Be sure you're getting the Pro! It has more features, looks better, and costs the same or less than the regular version. This is a great little headphone amp, especially to improve a PC's sound quality and volume. It's small, simple, has some great features, and the sound quality is excellent. I can't compare it to the real pro headphone amps out there that cost some serious cash, but I can say that my headphones (Sennheiser 280Pro and 555) both sound a lot better with this amp. The bass range on my 280's - which was really weak coming directly from my PC's audio - sounds much more deep, clean, and sharp. Features: --------- -- Two stereo INPUT types - RCA or 1/4 TRS -- Supports FOUR headphones, each with it's own individual volume slider. -- Each of 4 outputs has two stereo jacks to choose from: 1/4 or 3.5mm -- It's small, light, and has four thick rubber feet. Safe on any surface. -- Great sound quality, especially for amping PC sound hardware. More info --------- -- No power switch, so it's always on (VERY low wattage, though) -- It's powered by an A/C power brick. Has a green power indicator LED on top. -- The volume sliders have only one detente, or notch at the half-way point to let you know how far it's been pushed. -- Above the slider detente, this thing gets These go to 11 loud! Watch you ears. ;) -- If you want to use it for speakers, make sure your speakers are self-powered. I doubt this amp will support un-amplified speakers. If you're a true audiophile who needs to have the absolute best sound available and you can spend the cash for that quality, this amp isn't for you. You probably have better headphones than me, and you probably aren't using the amp on your PC anyway. I am extremely picky about my sound quality, but I can't yet justify spending $400-$2000 on a serious Pro headphone amp. With the headphones I have, though, this little amp does a GREAT job and is definitely worth the price.
