The KCS75 units are very capable of good-to-excellent sound reproduction, capable bass response and "transmission to the ear", fair mid-range quality and very capable treble response with clear crisp sound

+ great sound, on par with the legendary Koss PortaPro Headphones with Case although with less forward lows+ decent range, bass is surprisingly present given the modest size of the drivers and light weigh of the assemblies+ extremely comfortable, very lightweight+ minor, but super easy to put on/take off+ very efficient, can be driven to reasonable SPLs with modest amplification- let's be honest, kind of dorky looking...- minimal/next to no isolation - obviously these are designed neither to minimize sound leakage nor limit ambient noise- a bit flimsy, although a good reputation for durability under normal operating conditionsOverall, for the money, these are really hard to beat.

For as cheap as they are and as flimsy as they look, they have incredible dynamic range with bass frequencies far exceeding most earbuds I have tried

The effective volume range is also very strong

The mid range on this headphone is excellent

Good range for the pricetag.

Excellent audio range and volume

The wiring might be flimsy on the original versions but, they are a good solid, great range headphone

and I hear all my favorite music as it is meant to be heard with an exhilarating full range of sound.

They have a decent full range without ultra heavy bass

Great Sound, good range, comfy, good price

The highs are crystal clear, mid-range is nice , and the bass is enough

Honest true sounds and volume range

These produce a modern full-range sound

In the most simple terms a wider FR equates to a *potential of increased listening enjoyment because even at lower volumes a greater range of sound frequency is available to hear

The sound range is quite good, and it is a good unit for around the house or in hotel rooms - where noise is low and you want to be able to hear what is going on around you.

The range is slightly limited and not 'crystal crisp', but absolutely enough to enjoy a variety of music

My reference speakers are Infinity IRS Betas which are wonderful throughout the audible range, and these Koss Earclips sound very similar

Clean and strong distortion free bass with clear relatively smooth mid-range and extended treble.

Great bass, nice integration, very serviceable middle and treble ranges

Plus the dynamic range including the bass is amazing

Crisp low mid and high range, beautifully integrated

These are great for audiobooks and podcasts, as the regular vocal range is exceptionally crisp, articulate and clear.

The range is slightly limited and not 'crystal crisp', but absolutely enough to enjoy a variety of music

I like the KSC75 as they are on my cell phone

The bad:a) Not clear to me yet if these are as water resistant as the Sennheisers

I've been bouncing back and forth between my Zune and Apple earbuds, but my ear was starting to ache a

I've worn them while running as well as during Insanity work outs, and they have surpassed my expectations by a long way.

Build quality perhaps not that good as it seems to be made of some sort of plastic but for the price did not expect anything better

Just . . . displaced.)Still, for this price, you can comfortably buy (and eventually, lose) 3 to 4 pairs of these for working out in the gym or your yard, and have sound quality that's just as good as or better than any single pair of headphones you could get for their combined price

I like these a lot, but the fit over the ear isn't as snug as I would prefer

I have Sennheiser HD600s for home use and Ultimate Ears Triple-fi 100s for mobile use (requisite upgraded cables to boot) and these cheapo Koss 'phones sound nearly as good as my other cans.

Full bass, good mids, excellent highs as you would expect.
