Yes, the original SP/3 was introduced in 1958 and is widely recognized as the first stereo headphone. This current version is a reissue that celebrates that legacy.
The reissue maintains the iconic look and sound characteristics but uses modern materials for durability while staying faithful to the original design.
The SP/3 offers a warm, vintage sound signature that is unique compared to modern headphones. It’s not intended for critical listening, but rather for nostalgic enjoyment and collection.
As a limited reissue, the SP/3 holds appeal for collectors. At $10, it’s an affordable entry into Koss history, and its value may increase over time.
I bought these for my vintage stereo setup. They look and sound like they're from 1968 because they are! The quality is surprisingly good. The sound is vintage, with a warm and slightly dark tone. Great for rock and jazz from that era.
These are a neat novelty, but they actually sound decent. They're not audiophile grade, but for retro gaming and old records, they're perfect. The build is solid, and they're comfy enough.
I'm a collector of vintage audio. These SP/3s are a must-have. The sound is surprisingly clear for such an old design. At $10, they're a no-brainer. I use them with my vintage receiver and they look great.
The sound is okay, but the earpads are hard and the headband presses on my ears. I feel the history, but I can't wear them long. Great as a collectible, not for daily listening.
These are exactly what you'd expect from 1968. They feel old-school, but they work. The sound is actually not bad—a bit bassy. They're fun to use with my turntable.
I bought these just for the novelty, but they've become my go-to for watching old movies. The sound is mono? No, it's stereo. The sound quality is surprisingly good, and they're comfortable enough for an hour or two.
If you're into hip-hop or electronic, these aren't for you. They lack bass and are very mid-focused. But for oldies, they're fine. The retro look is cool.
My dad loved these. He remembers having them as a kid. They work well and have that classic look. He uses them for his vinyl collection.
I was skeptical paying $10, but these are a great deal. The sound is warm and full, and they're surprisingly loud. The build is solid, and the ear cups are comfortable. A great addition to any collection.
These are designed for smaller heads. They squeeze my head and ears. They might fit a child. Sound is okay, but not comfortable.
