PlantronicsDSP-400 Digitally-Enhanced USB Foldable Stereo Headset and Software

Works as advertised. Quality of sound very good. I use it with skype and dragon naturally speaking (DNS). With the latter, it picks up my voice very well. I like the fact that it folds nicely so it fits in my drawer, also the fact that it has a long cord. It's also great that I can increase/decrease volume in one move, w/o without actually having to use my mouse. Same with the mute button - particularly useful for me when using DNS. The headphones are comfortable, and not too tight. The adjustable head piece/band also works well. On the downside, it is a bit bulky, and it has no hard case, so if you plan to travel keep this in mind. The mouth piece locks in place at some point and you can't move it further down - this is a bit of a problem if you are trying to read something from a piece of paper that is on your desk. It blocks your view somewhat, but it's not really that big of a nuissance, and probably no one would notice unless you use DNS. These are very minor issues, though... Overall, it's a good product for a reasonable price. Would buy again.

This headset offers good comfort, especially for the price. I use this headset almost entirely for VoIP (i.e. Skype) and have had great success with the audio quality both on the headphone prtion and microphone portion. The fact that it is a USB headset is wonderful because I can select it as my audio device for Skype, but I can still have my computer speakers playing music, even while I'm on the phone. That would not be possible with a standard, non-USB headset. Installation was also a breeze, everything was automatic for me in Windows XP Pro SP-2.My bigest complaint is the exteremly long cable and large box that hangs off of it. This is an issue for me because I use a laptop and this headset travels with me all over town everyday. Unfortunately all USB headsets have some time of box hanging off of them. The benefits of a USB headset for me outweight his problem, and I'm happy to lug it around, but still wish it wasn't required.I have used this headset for playback of music and while the quality isn't great, I don't believe that is this headset primary purpose and for the price I think it performs acceptably. Overall I would recomend this headset, especially for VoIP like uses.

I ordered this from amazon about 4 days ago and received it yesterday, this was with free shipping, wow! The first thing I found funny about this headset is the "foldable" feature is supposed to appeal to those who travel. However, the EXTREMELY long cord and very large box that attaches on the wire makes it impossible for quick/easy travel. I fixed this problem by actually wrapping up the excess wire with twist ties but the large box is quite annoying.As for sound quality. I use this headset only for Skype and World of Warcraft. The gaming sound is pretty good quality and it does work well with Skype. Luckily, I won't be traveling with this headset. So, basically, it does what I needed it to do. This is highly likely not the best headset out there, especially at a price tag of $40. It should be a little better. It is comfortable but the folding feature makes me wonder if the headset is not easily breakable or will wear very easily over time, and if it does, it will be useless. So, let's hope that does not happen! :knocks on wood: I'd do a little more research before spending 40 bucks on this one though. I think you could do better.

I use this with Dragon Naturally Speaking. This is my 2nd unit. The 1st started showing wear after 6 years. No deep bass for games. Get the 500 model instead.Works with Mac and Windows. I am told it works with Linux as well.The down side is the long cord can get tangled. The mike wind screen falls off with almost no effort.And the sound quality of the mike is great. Being USB based, the mike input isn't reduced by the electrical storm inside the PC case, which messes with the best sound cards on mike input. Most high end sound cards focus on output, not input.IF you need high quality audio input, AND you want a traveling headset, look no further.One more little down side. They have made some internal changes, so Windows thinks my OLD DSP-400 is different than my NEW DSP-400. I solved that by putting the old one on the Mac and leaving it there (after using silicon glue to keep it together).At the price, just get a 2nd if you are going to travel with the headset. They take a solid beating (for a while). I have not been able to beat the DSP-400 no matter how much I have looked and tried other units.Tcat

The microphone is incredibly sensitive to electrical noise from laptop power supplies or powered USB hubs, causing a very obtrusive hum when used with applications such as Skype. As a result this Plantronics model can be used on laptops only when running on battery power. Since that's not practical, I am now the proud owner of a stylish $40 paperweight.It would have been easy for Plantronics to include a low-frequency rolloff around 120 Hz which would filter out the hum, but leave voice signals unchanged. (Unless you're singing a bass part....)It's a pity, really, because otherwise the sound quality is quite good.

I got Avaya RoadWarrior up and running on my computer to use when I work remotely. My co-worker told me to get a GN Netcom headset but I figured I'd save some money and get this one. Big mistake.There is a major problem with some laptops when the power cord is plugged in, the listener on the other end has what sounds like you in a an airplane during flight. The humming goes away when you unplug the power cord but that doesn't help me, I need to be able to use it when the power cord is plugged in or not.Anyway, I chatted with Plantronics support and then informed me that it's a known issue with no work around except to unplug the power cord while using it.So, it's getting returned.
