The RP-DJS200E is processed very tidy for the price. However, the sound a bit dull, very detail goes lost, quite mushy. Overall, for the price - I paid about 15 - but passable. But he provides tidy.
For the normal price this handset but not worth it. Access then prefer to Koss Porta Pro, the "On the Road Headset" in the price range of 30 at the - 70 on all doubt.
Conclusion: worthwhile only if particularly favorable. Well then, for example for the children. As you can very well get over a defect then.
Otherwise rather buy a Koss - if you want to have good manners.
