So here have mostly kept the authentic word reviews. I bought the plug because I like to listen to electro and club music which is also sound neat. After I (because I did not want to invest soo much) have already made the odd mistake now I am happy - not least because a top bass (and I have no equalizer, also find it not too dull) from these little things coming. But have to say that I really like in the stereo bass purely turn again. The price is absolutely right - have looked at Media Markt and because there are the same Koss Plug, but the same in a different price range. In fact, I do not think that you get a similar quality for the money. Unfortunately, the handling is a bit more difficult - to get good sound and seat brauchts beginning patient a few seconds. Who but rather the high notes (guaranteed little bass) and a simple handling with a comfortable fit in the ear in the low price class looking, I recommend the Hama HK 257th Incidentally, I did not think you will notice from his surroundings now nothing more, but I never rotating the volume very high (Still nothing for the road).
CONCLUSION + Who likes fat bass will never give up the plug again + Top price for this quality + While skating and cycling these things fit like a glove in my ears - Handling similar to earplugs. Who can not have should perhaps consider that again, because if the plug has been spreading in the ear, it feels like. Also you have to just like earplugs press bissl and push until it fits snugly.
