after two weeks of using this headset always appears as a compromise model between several criteria: - Value, the price is close to that of high-end models, yet the finish is quite good with a sense of relative strength. The son are fine but replaceable (full price for proprietary connectors). For the record I have headphones AKG K312 with the same model son that I use almost daily for nearly four years without any of my previous helmets had held more than 1 year (and again ... ), so I hope - Comfort / insulation is quite good (the pads a little too warm ears, I must say that I am very sensitive to that), holding a helmet is average if we start moving your head, and appreciable thing headphones Lightweight and compact. Insulation is good or very good taking into account the size of the helmet (hence the ears that heat) for me it was one of the first criteria of choice - Sound (Basseux / not Basseux): K 450 has lots of bass, that said this is far from the disaster met with other manufacturers (or about 460 of these in AKG). Fortunately these do not invade too low mids and highs are clear with good spatial. The set is rather convincing, there is better but it is much more expensive (Phillips fidelio M1 or Schennheiser HD25). I tried thirty (or more in Cobrason in Paris 11th) nomadic helmet models and compared to models in the same price range this was the best compromise for my personal tastes. Note that it comes with some rather useful accessories including protective case which protects well, but at the cost of some effort as the zipper is rigid and the reduced size of the case at most
Small addition after 6 months of use: always work perfectly, failure ears that heat has become an advantage in winter and the port became enjoyable.
