Pros: Good sound quality and clarity. Great to wear for long periods of time. Sound Isolation is good (More in the Discussion)

Cons: Thin and short wiring. Bass may rattle (More in the Discussion)

Overall Review: I've been wanting a Sennheiser for a long time after knowing how reputable their headphones are and I finally found my chance with these. It was affordable for me so much so that I got one for me AND my brother who sorely needed it. The poor guy has been using old clip-on headphones that came free with his Nintendo DS... which was over 7 years ago! The HD419s would have to be the best bang for your buck if you want to listen to your music or play video games within a remedial setting or studio. I enjoy putting these on over listening through Logitech 2.1 Speakers. I know that's not saying much for you audiophiles out there but, what can I say? I'm on a budget. On the topic of Sound Isolation: I've dedicated these headphones for my little closet studio only and so it blocks most noise that pervades the house, like calls to dinner or yells to take out the trash. DISCLAIMER: I would not take these cans outside. On the Topic of Short and Thin Wiring: Yeah, like everyone else is saying, the wire is thin, short and feels cheap. I'm nervous about moving my head around for in the event I yank it the wrong way. As with the previous disclaimer: Do not take these outside. On the Topic of Bass Rattle: I did a quick audio-check after a month of use and the only problem I seem to have is that, at full volume, the bass rattles. I read somewhere that a good rule of thumb is to stay about 70% of maximum volume, which, at that region, the rattling is near to non-existent. So, keep the dB down and its good. I do find this pair of headphones wanting on the volume side. I really good song kicks on, I max the volume and "I still don't feel the music." Maybe that's what an amp is for, I don't know, but this is nothing to prevent anyone else from buying pair. I'd highly recommend it for someone on a budget.

Pros: Great customer service from company.

Cons: Reliability.

Overall Review: Call it bad luck or not, I received TWO duds from NewEgg after purchasing ONE unit and both with the same problem. Every hard drive I tried (and I have three, one 3.5", the others 2.5") would not appear in "My Computer" even though the RX-DU100 is recognized after I plugged it in. Should have been plug and play stuff really, I mean, come on!? It shouldn't be THAT hard for me to use my hard drives. I would go about this device with caution. The service is great (after all they gave me another unit for free) but reliability... it's a gamble.
