Product Description

Amazon.com Product Description

Koss Pro4AAT Titanium Pro Headphones are rugged, closed-ear headphones built tough enough for broadcast use but at a price even the smallest studios can afford. Built for extreme durability and with a closed ear design for maximum bass and isolation, these headphones have a wide frequency response of 10 Hz-25 kHz and feature titanium-coated high polymer diaphragms for crisp, accurate sound and oxygen-free copper voice coils for signal clarity.

Product Description

This full-size professional quality stereophone has long been the headphone of choice for broadcast and recording professionals whose careers demand reliable equipment and superior performance. As the first dynamic stereophone to deliver true full frequency, high-fidelity performance, the PRO4AA set the standard when it was introduced in its original form in 1970. In the late 1980s after long service, it was retired and replaced by a newer model. Customers clamored for its return, and by 1988 it was brought back by popular demand. Since then, though we've incorporated performance-enhancing technology and updated its style, the essence of the PRO4AA remains unchanged and it continues to set the standard for performance and reliability today.The PRO4AA features dynamic elements for an exceptionally wide frequency response from 10-25,000 Hz. Designed for frequent use over extended periods, the PRO4AA's durable steel and rubber headband is generously padded. Adjustable slide bars ensure a snug fit, also critical for hearing every note and keeping unwanted sounds out. The heavy-duty, single-entry ten-foot coiled cord affords ample flexibility of movement. It includes microphone mount hardware for complete versatility. The PRO4AA has a 6.3mm (1/4") plug and an 8 foot coiled cord.Whether you are a sound professional or simply love music, the PRO4AA will deliver excellent isolation, accurate sound reproduction, and the excitement of a live performance to your recording.

This review is from: Koss Pro4AAT Titanium Pro Headphones (Electronics)

O.K. my dad, who was in broadcasting over 20 years ago owned a pair of these, they broke finally, he called Koss, they said send them in, we have a Lifetime Guarantee on all our headphones. They told him they didn't have the exact model he owned since they were so old, but would send him the updated version.(Pro4AA Titanium) While he was a little skeptical of the quality, (I got the story about how they just don't make things like they used to.) and sad to have to send them in, he acted like a good friend died, we finally boxed them up and sent them off. (Cost us $7.00 at USPS) About a week later these arrived, no charge. He took them out of the box and was complaining about how they just weren't the same, then he put them on, and started listening to music, he has had a smile on his face ear to ear ever since, and told me how much lighter and more comfortable they were, he also mentioned that he hated to admit it but they also sounded beter. Needless to say while there was some sentimental value with the old pair he is very happy with the new pair and the improvements that have been made over the years. I also found out from the Koss web site that they invented headphones over 50 years ago, and it is thanks to them that all of our products today have a headphone jack on them. If you want a Headphone that you can pass along to your great grand kids get a pair of Koss Headphones.

5.0 out of 5 stars Excellent sound, quality for a fairly reasonable price., March 26, 2004

This review is from: Koss Pro4AAT Titanium Pro Headphones (Electronics)

Myself being new to the world of higher-end headphones (it seems full of crazy lingo and brand loyalty), I searched the net for several days for what were considered the best brands. I chose these Koss because I knew the name (and the lifetime warranty, and stories of no-hassle returns, are far more than Sony, Sennheiser, or the rest can boast in the same price range) and I wanted an isolating set of headphones to use for studying (while my roommate pounds out Jay-Z and OutKast on his stereo). The Sonys seemed a little gimmicky (90 day warranty?) and overpriced. I looked at some Bose phones, but they were far out of my price-range. The Sennheisers, according to some "purists", provide the best overall sound quality (although I couldn't imagine anything surpassing these by much), but they appeared too bland-looking and fragile for my tastes.

When I got these I loved them from the start. I never knew they made headphones that sound better than a quality stereo! The sound detail is excellent with audio CDs and MP3s, and the bass is strong but not overpowering. I haven't yet tried these out on DVDs, but I would imagine they would be awesome. As far as isolating goes, I don't know why you would need any type of noise-cancelling headphones (which sacrifice sound quality for technology), because with these babies on, all you hear is the music. My roommate has to throw something at me to get my attention when I have these on! For the newbies out there: these are not for use with a portable CD player or MP3 player; they fall far short of the amplifying power needed to push these phones. If you want something sensitive enough to use with a portable (look for something with impedence around 32 ohms as compared to 250 ohms for these) buy something from the Sennheiser line, as they are also lightweight. I use these mainly to listen to rock, rap, and R&B, with some classical here and there (when studying). These are ideal for the first three but the quality of the classical is not what I would imagine a "purist" would deem extraordinary.

The look and feel of these phones just exude confidence in the craftsmanship and the quality of parts. Simply put, these are some awesome looking headphones. The pads are comfortable but will stick to you in warmer weather. If you don't think you'll be able to handle two extra pounds on your head for an extended period, don't buy these. I only find slight discomfort in my neck after wearing these (and I wear them for 2-3 hours at a time). The 8-foot cord and 1/4" adapter provide ease of use while wheeling around a stereo or computer.

I would recommend these phones to anyone who wants some high-end headphones (from Koss, the people that basically created the headphone) for isolation or just overall excellent quality of sound, with a guarantee for the life of the product.

This review is from: Koss Pro4AAT Titanium Pro Headphones (Electronics)

Just got these phones last night & I am loving them. I bought them from amazon along with Blink 182's new album on the 18th. I got both items on the 20th! Great service.
Anyway, back to the phones. I pulled them out of the box, adjusted and then put them on. They look great and feel very comfortable. I have a fairly large head, but not the biggest. I dont think these phones would fit anyone much larger than me, I put them out to their largest setting. One reviewer said they were too heavy. They are going to be heavier than normal walking headphones, these are designed for studio and field recording. If you are looking to wear these all day to listen to your walkman, dont bother! While they are very comfortable, after an hour and a half or so of wearing them, your ears will get a bit hot. The cups fit very stug and dont leave much room for your skin to breath.
As for quality, I love these phones. While listening to the new Blink album I could pick up on every little detail, even a few mistakes! They are great for bass as well. The middle of the song 'Obvious' has a great low hit from a bas guitar which sounded great on these phones.
Cant forget to mention that these things are sexy!
