A Real Deal When On Sale

Buy it on sale. It's a bargain with a complete setup. Leather bag, strap, etc., to hold everything when traveling. Great to take on a long car trip (assume as a passenger) or train. Only company that does this. The sound is what you get on whatever medium it plays on and basically as flat as anything out there - meaning you don't get a "fake" made up sound and is TRUE on its end. It's clear, precise, open, and musically flows.
I don't know why people complain about the controls. It's two concentric separate volume controls to adapt to anyone's uneven hearing. Turn one or the other up or down and when you get it set to your liking you just turn the two as one as it is made to do.
It comes with everything to play whatever medium you have. It is light due to it's plastic construction. Anymore and you'll be paying through the roof for it. It IS nicely constructed and looks very good and can find no fault in its looks, really and if you ask me the ear cushions that come with it look the best and the most elegant. Don't change it out. It is very comfortable.
The amplifier is also nicely constructed for the price. The face plate scratches very easily and I would not recommend you wipe it with anything. For what you get and the price I can think of NO better deal on the market and this is speaking for decades it has been made. However, I would not put too much faith in the warranty.

Great set! Crystal clear, great details. Not tiring to listen to. Bass is accurate but not intense. Responds excellently to EQ unlike some of my other headphones. Raising the bass did not harm the sound at all. I put a Vali, Loki, Modi stack in front of the energizer and am pleased with the results. The set is super lightweight and very comfortable. It may be an old design but this is still a 5 star product.

Headphone nirvana achieved!

I was introduced to Koss Stereophones in the late 70's and currently own everything from those first Pro4AA's to Pro4S' (total of 9 different models for different uses over the years) and they just keep getting more satisfying. Didn't think much could be done to improve on those Pro4S' but always dreamed of owning the "top of the Koss food chain" electrostatics and finally had the opportunity to purchase ESP950's of my own. WOW.
Reviews for these and the Massdrop version are overwhelmingly positive and loaded with superlatives and, now I know why.
All the adjectives apply: clean, pure, crisp, balanced, etc. and the imaging has to be heard to be believed (it is so open you forget you have headphones on). Comfort is excellent and, from experience, I know these are a lifetime purchase quality wise.
If I had to pick a nit, for me, the concentric knobs for controlling L & R volume levels make changing levels more difficult than it should be. A tension fit to each other would help keep them sync'd.
Listening experience wise? Don't change a thing! Absolutely as phenomenal as reviews have said and then some...
