Review: Light, but packs a punch - Earphones are lightweight, compact & fold-able, boom mic can be adjusted to anywhere you prefer, or out of the way. Package arrived pretty torn and beat up, but the contents were fine. Lightweight unit feels like it couldn't take much punishment, but I've had two of these same headphones and they have lived up many years of usage. Cord length is exceptional, possibly even longer than expected, and I find ways to double-back the cord. Sound output from my PC sound card seemed to be less than satisfactory, so I went with an external mixer/amp combination, and the quality became what I've come to expect from Koss. Standard mini (3.5) stereo plug for portable mp3/phone jack outputs, Koss used to supply a 3.5 mini to 6.5 standard phono jack converter, but didn't get one in the package. Going from a PC sound card 3.5 mini jack to a mixer phone jack I needed to have the converter, but as I've bought a few headphones over the years, I had a couple spares on hand. Simple plug-n-play; plug the earphone icon plug into your output, and the mic icon plug into your mic input, and you're ready to rock 'n roll. No batteries, or volume controls on the unit to get in the way, or add extra weight. Simple audio headphones compatible with any device that uses a mini 3.5 TRS stereo plug output, but as I have found, the device may not have enough output watts to give the earphone drivers enough power to really give the sound quality they can deliver. All-in-all, the SB-45 Stereophones perform both in the mic, as well as the sound quality of headphones costing far more. Well worth the purchase price.
Review: Quality product - Great sounds good fit and comfortable. I recommend them

### ⭐⭐⭐⭐⭐ Quality product
*by A***R on April 13, 2026*

Great sounds good fit and comfortable. I recommend them

### ⭐⭐⭐⭐ Great so far! Noise cancelling a little too good
*by A***N on April 2, 2011*

I bought this for my boyfriend for his birthday... a few comments from him and me: 1) The noise canceling is fantastic. I can pretty much yell at him and he won't hear me. (This is also kinda hilarious when he's playing Left 4 Dead...I can tap him on the shoulder and he jumps about 3 feet) 2) The sound is excellent. I listened to it myself. A lot better than the $40 logitech pair I bought myself. 3) He's been wearing them about 2-4 hours a day since getting them...he complained the first day they felt a bit tight, but no comfort complaints since. 4) The mic sticks out pretty far from the face. He was worried about that at first, but everyone seems to hear him so no more concerns there. 5) They're huge. They don't look it in the picture but they're very large. Like the size of headphones you'd find at a gun range or for use on private aircraft. Not terribly heavy though, considering. 6) There isn't a volume adjust on the cord. This didn't occur to me, but it was pretty much the first thing he noticed out of the box. All in all he seems happy...so I'm glad I chose these. Update 3/11/2013 - they're still getting daily use by him for hours a day and still working as well as they did new. No durability issues to date, nor has he felt any need to replace/upgrade them. Update: 11/19/2013 - they died this week. As with most complaints, it was the mic that went. Still, they have probably a few thousand hours of use on them and lasted over 2.5 years. For $30 I'm going to leave the 4 star rating alone and say that they were still money well spent, at least in our case.
