Not sure what people are talking about when it comes to weak bass. The bass isn't weak, it's just pleasant. It's just right in my opinion for every day relaxing listening. Now, if you're in the mood for some loud pumping beats, you might want to switch to a different pair. These headphones are just fine for those who aren't a basshead.

I bought these headphones on ebay back in 2008. These are the biggest headphones I've ever seen. I love the huge soundstage these headphones are capable of producing. The bass is awesome as well. It's like a pair of subwoofers strapped to your skull! Overall, I do like the sound of these headphones although they have a pretty annoying peak around 2kHz, but they smooth out with a little bit of EQ. If you're into vintage headphones, this would be a cool pair to own.

I bought these headphones used on ebay back in early 2009 from the original owners. The headphones were dirty, but in unused condition. They came complete with original box, instruction pamphlet, and packaging materials. The sound quality is very good for a late 60's to early 70's headphone. They sound way better than anything I've ever heard from this time period. Bass and mids are decent, but the highs are a bit rolled off. They still produce clear enough sound to be considered Hi-Fi in my opinion. They became very comfortable after I was fortunate to find a pair of pads from a junked pair of Neumark headphones that fit the SE-30 headphones perfectly. They are thicker than the stock earpads and don't suffer from decay like the stock ones. I'd definitely recommend these to anyone interested in vintage headphones.  

I bought these headphones back in 2007 for lightweight portable use. These have been the most reliable and longest lasting of any new pair of headphones I've bought to date. The sound quality is decent for the price. The high frequency response is not the greatest but overall not bad. I'd recommend these headphones to anyone on a tight budget, but wants good quality sound.
