noise is fairly loud but it depends what your used too. the engine is right benhind your head but its not that bad (like i said compared to what your used to!)
You dont come out with ringing ears or anything and they come with a mini disc player so obviously not louder than the stereo and you can talk etc. It makes a nice roar when you get higher up the revs (i.e driving it properly) but normal driving is fine. Its not a problem at all TBH.
