    Plantronics C520-M reviews

    Blackwire C520-M USB Corded Headset is rated 3.8 out of 5 by 19.
    Rated 2 out of 5 by from Not great for Office Work Sound quality for phone is great, but for doubling as stereo headphones, find another product with a microphone. Even ear buds with a mic are just as good. The only good is the microphone, which filters  additional noises. If it's for a phone, get the 1-sided Blackwire 510. If you want good sound, any home headset is better (including cheaper ear buds). These are uncomfortable if you want to use only 1 side. Also, too much pressure for a normal size head.

    Rated 4 out of 5 by from Sound quality is great, headband is uncomfortable I have two of these, a 520 and a 700 series. I like the quality of the sound, it's great for music, webinars and calls. However, the headband seems to have been designed for Frankenstein. When stretched on, the top becomes flat and puts pressure on the top of my head. For all day wear, that can become painful, in spite of the padding.

    Rated 3 out of 5 by from Good noise canceling, bad "voice injection." Pros: Great build quality, very quiet, good voice quality, eliminates background noise, cuts echos (assuming), comfy earpads, microphone conforms to your face (bendable). Adjustments for bass cut, mic enhancements (noisy room), loudness cut (people who both whisper and get really loud). Should be good for long calls (won't press and hurt your ears). Cons: They inject your voice into the speakers, which can not be adjusted or turned off. This throws you off a bit while talking. Not enough padding on top (or alternately) perfectly round on top. This puts more pressure on the top of your head, which is annoying. Missing advanced adjustments for music or movies like EQ, tonal, DSP effects (warm sound, dialog enhancements, stereo spatialization, treble boost). Also as with typical USB headsets, you can't adjust the sound quality like with analog headsets. So forget about using these for listening to music.

    Rated 5 out of 5 by from Fantastic! We just purchased two of these headsets for new staff members and they both are impressed with these headsets. Easy to use, they do a great job in blocking out noise well on a call or listening to messages. Worth the investment.

    Rated 5 out of 5 by from Excellent call quality and noise suppression! I bought primarily for Skype calls and this is an excellent fit. Sound is crystal clear and background noise suppression is excellent. can tailor the amount of suppression on the mic. If you want quality stereo headphones for music, get one purpose built for that. People, realize that most headsets for phone calls are tuned to enhance mid-range frequencies - not for music.

    Rated 3 out of 5 by from Not good for gaming I really like he simple design and it has a great microphone. However, the sound quality always sounds like I'm in a or something. All the audio sound distorted and far away which is very bad for music, videos, gaming, etc.

    Rated 4 out of 5 by from Great sound I really like my headset. The sound quality is good. The microphone is bendable. My only down fall to this headset is it pull my hair. It is great for short hair but longer no so much

    Rated 1 out of 5 by from What happened..? What happened? If this is the successor to C420 Plantronics really messed up. Build quality has gone down, now cheaper plastic is used and it shows, even the metal parts have been replaced with cheap plastic. I'm on my 2nd pair in only 2 months. The old C420 lasted me 4(!) years. Sound quality is horrible in comparison. I'm not joking when i say these sound like a pair of really cheap iphone ear plugs, where as the c420's were excellent for talk and media consumption. I would even go as far as saying the C420s were close to Koss Porta Pro's after a few hours of burn in time. The C520 are absolutely horrible for any media consumption, forget music. The sound is flat and boring, no characteristics at all and the music disappears into a broken sounding screech. The comfort is also worse, these are more stiff and has a tighter angle which makes them press really hard on your head. The C420 were excellent in this regard and you could keep them on for 8 hours straight, I cant do 8 minutes in these. Ive used the C420 over 4 years until they broke, sadly the c420 is no longer made and I now have to stick with these. Im not exaggerating, i'm very disappointed in these "premium" headphones. Make the 420 again!
