3.0 out of 5 stars Good, but..., 18 Feb 2007

By	M. Richards (Devon, UK) - See all my reviews (REAL NAME)

I bought the Spark Plugs after I had misplaced my Plugs (the 1st Koss version), which were very good. I thought that the new updated Plugs would be better, however for me, they weren't as good. The white plastic speaker part is too deep for me, and protudes further out of the ear than the Plugs, which people can live with, and they ARE white, yey. However for me the biggest difference was that Koss had promised a better sound than the old version Plugs, but IMHO (I realise I am no expert), they're very bassy, almost too much so, with not enough treble and mid. You can however, remedy this by adjusting the sound qualities on your generic MP3 player, ie treble boost, which I didn't need to do for the original Plugs.
I suppose what I'm saying is if you're buying something like these for the first time, I'd seriously consider buying the Plugs, rather than the Sparkplug. What properties DO share though are incredible comfort, very light weight, good sound insulation and good bass. I hope this helps.

5.0 out of 5 stars Better than sony, 21 Feb 2006

By	Lloyd Pople "dr-hfuhruhurr" (UK) - See all my reviews (REAL NAME)

I previously owned the Sony MDR-EX70 - very comfortable but the sibilance was unbearable. No such problems with these superb Spark Plugs - slightly less comfortable but fantastic sound. I doubt you'd want them for classical music but for anything else these are awesome. If you like bass and sound isolation these are definitely worth a try.

5.0 out of 5 stars The best ever !, 4 Aug 2006

By	audiofile 118 (glasgow United Kingdom) - See all my reviews

I bought these about 4 months ago and they are fabulous. I was looking for something to replace the dreadful things Ipod provide with their quality player. I have found that the Spark Plugs stay in well whatever I am doing and the sound quality is very, very good. I'm sure what I'm doing that the guys who found them uncomfortable aren't but I have had them in for a four hour flight and never found them in any way uncomfortable in fact my only beef is that after about 2 hours you need to refit them. As for the sound qulaity the treble is quite natural and the bass is tight and controlled. The reason I think some people may find the bass a bit heavy is that for most other 'phones you need some bass boost in the equalisation and if your Koss's sound bass heavy turn the boost off. You will be thrilled with the results.
