Plantronics Blackwire C720-M Wired Headsets - Retail Packaging - Black

If you make a number of conference and VoIP calls, especially through Skype this is a wonderful set. Here's all the reasons I love this headset: 1 - Bluetooth connection - I can listen to my music and work either from my iPhone or the PC, and take calls without missing a beat when they arrive on either the cell or the PC. Just make sure you get familiar with the inline remote and how to turn off the Bluetooth. It took me a few days to figure that one out and I assumed it was always or nothing. It will fight like a frenzied shark to stay connected especially against other Bluetooth devices like your car's hands free during a call, while going 65 on a highway. Turn off the Bluetooth before you pack them in the trunk or you will go crazy on a call. All my fault for not reading the manual. 2 - Stereo headset - great sound for music and for calls! I love them as much as my high end earbuds for sound, but don't have to shove them in my ears, and they are comfortable enough for me to wear for hours. 3 - Noise cancellation microphone - excellent call quality reported to me by co-workers and friends. I was in a loud busy airport right by the gate (DFW) on a call with the boss and she said she heard it clear as a bell as if I were in a quiet room talking directly on the phone. Big win for conference calls - wish EVERYONE on my calls had this. 4 - Inline controls - these are almost perfectly designed for me. Volume control, mute and buttons to choose between VoIP or Cell calls. Not sure what would happen if I had one of each at the same time. But worth trying I guess. 5 - Battery built in to controls - allows you to break free from the PC and holds a charge for a good long time. I have not had it peter out on me yet during a call or music. I even used it to listen to an audio book all afternoon while I cooked dinner for Thanksgiving. As long as you are in range of the phone or Bluetooth source, you're good to go and can move around without any loss of quality, until you get too far away. 6 - Wearing sensor - can't recall the actual name, but it senses when you pick them up and when you take them off. Really helpful for Bluetooth calls, since it can auto-answer when you pick them up and put them on. Timing is nearly perfect for me. It does get hokey at times if you are listening to music or something and bend over to pick something up or tie your shoelaces, but it pauses the source (iPhone at least) and resumes immediately so I can't say that's a bad thing. 7 - Flexible boom mic - can be adjusted very easily and moves out of the way when you just want to listen. 8 - Simple to use software to help control or set features and keep an eye on the battery level, but you don't need to use it at all if you don't want to do so. Things I don't love: 1 - The mute button is a great feature to have inline (common) but there's a dead period while the little lady's voice tells you "Line Muted" or "line unmuted", which is just long enough to be a pain and cause you to miss conversation. So I rarely use it now, it just takes too long to shut up and be or not be muted, and I miss some details being given during a call. I just use the phone's mute or on the PC when I need to. This would be great if you could turn off the voice notification and just beep quickly without muting the sound you are hearing. I do love and need the confirmation on Bluetooth On/Off, so hope that never changes. 2 - Doesn't look like I can change the battery. Meaning I may have to part with these someday for a new pair, and that may mean different features I may or may not like. Not such a bad thing, but #1 seemed lonely here so I had to find something else. Not really much to say bad about these. I hope they never change this model much, only that they tweak the mute notices and such, since I truly enjoy these and am one of the pickiest people on the planet when it comes to tech devices like this.

This headset works well enough. It limits background noise from my surroundings, in terms of both what the user can hear and what the parties on the other end of the conversation can hear. One of my favorite features is the lighted mute button on the little control unit, as I spend a lot of time on conference calls on VOIP. The other feature I am enjoying is the bluetooth connection with my cell phone, which allows not only allows me freedom to move about during the call, but the mute button is very useful with the call phone as well. Cell calls can be terminated or started (with Voice Control) with the headset. I have connected the unit to my PC through bluetooh, but it needs additional software to make it useful with VOIP. USB connection works well, but the unit is configured to control Lync, which I don't use for phoning. It would be nice if it would control Avaya or other phone software, but it does work well as a headset with Avaya. My least favorite feature is the placement of the control unit along the line. The amount of line is enough to comfortably clip the thing on a belt or pocket, which is great for when you're walking around. But for a seated office worker, the control unit hangs down into my chair, where it gets caught on the chair mechanisms. Consequently, I keep a foot+ of the cord hanked with a tie, so that the control won't hang lower than my waist when I'm sitting. I initially set the unit up to say "Mute On' and "Mute Off" when the mute-state changes, but I've decided that was not necessary. In fact, it's intrusive. If someone asks you a question while you're on mute, the "Mute Off" is superfluous when you hit the red button to come off mute, and it delays your response time. I could probably talk over it, but I find that hard to do. I want to change that setting, but the software no longer recognizes the unit. That's probably something I just need to figure out. Another slight debit is the comfort of the unit. The earpads are comfortable and they cut out sound from the outside, but the leather-covered piece that goes over the head is not well padded.

I've had these headsets fro 2 years now, I've bought 13 more for my coworkers since we work next to each other and want to make sure the mic does not pic anyone else conversation. These do an excellent job on getting only the person talking and no other sound. They are super confortable and do a great job in noise cancelling. A month ago after continuous use for one and a half year the headset started making a small buzz, I would imagine something broke on the noise cancelling, so I thought I would have to buy a new one, to my surprise after calling their support line (0 minutes waiting to talk to someone) they guided me through register and they are sending me a new one, looks like these have a 2 year warranty!!

This headset rocks! I use it with Microsoft Lync for work meetings. I use it with Skype to video chat with my family when I'm traveling. I use it with my mobile phone (via Bluetooth) when I'm at my desk. And in between all those meetings and video chats I'm using it to listen to music via my laptop. The sound quality is fantastic. The auto switching from music to voice is awesome. It even knows to connect to the mobile phone when I put the headphones on my head. I'm totally amazed and pleased with this headsets features and performance.

Don't get me wrong: this headset has a great build quality but the extremely annoying "Mute on" voice message when enabling mute is a deal breaker. This is incredibly annoying when on conference calls and affects productivity when using the device, esp. when you have to mute/unmute frequently. PLANTRONICS, THIS IS A NO GO ! I've contacted Plantronics customer support and they say they have no solution for this, nor a timeline when this can be fixed. This is redicoulus and seems to be pure complecancy, given that this is a known problem impacting productivity and the amound of people who have been complaining. It's time for Plantronics to learn it the hard way then. DO NOT BUY THIS PRODUCT !

The headset worked great out of the box with Microsoft Lync softphone. The headset sound quality is really good. I believe it cancels noise so when no one is talking, it is so quiet I find myself wondering if I was dropped from the call. On my first call a person told me I sounded funny, so I downloaded their driver from their web site and that fixed the problem. Instructions only said to load the driver for additional features. So don't rely on the default windows driver. I also had to make it my default windows sound device to get it to work as a headset for videos. I am pleased with it and would recommend it to others.

Mostly this is great, and the ability to switch from computer to phone mostly automatically is great. Few things I don't like: 1) the connector for plugging into the computer is a bit finicky. Sometimes if I pull on the cord just a little, it'll lose the connection. It seems to lose the connection where the two pieces of the headset cord plug into each other, not at the USB connection (although the latter happens sometimes too.) 2) when connected to phone via BT, it will play all phone sounds via the headset, not just calls. This is usually fine, allows you to listen to music etc. (although sound quality for music is terrible.) But one thing I've noticed is that it cuts out sound from the computer (via USB) when playing sound via BT, rather than mixing them together. Result is that if I'm on a call via USB, and have to look something up on my phone, just the navigation sounds from the phone will cut out the sound from my call. Very annoying. So I usually end up turning off BT on my phone to avoid this. 3) It's not very comfortable on the ears. It's not terrible, but much less comfy than other headsets I've had that have cups that fit over the ears.

Extensively reviewed all the options for a headset for office calls and conference calls. These were highly recommended on the Wire Cutter and a few other places. First off, call quality they are superb. If I record my voice through my laptop or phone and compare that to recording my voice through these there is a very noticeable difference. I'm in a home office with no other sounds, yet normal recordings have humming or background white noise. Where is with the headsets it was just my voice. Sadly, I had to return them after using them for a couple hours. They do not fit my head at all well since the top is not bendable at all. After wearing them for about 10 minutes my ears hurt and the mouth piece rubbed against my face. the wires are very long and cumbersome. While it says its bluetooth if you unplug the USB part the wire that is permanently attached to the headphones is quite long and has a large volume controller. Not something you would want to walk around with. They may be the best for this style of a headset but this style does not work well for me all. Hope it works better for others.

Schönes Headset. Sitzt gut am Ohr und verrutsch nicht, Klang ist auch spitze. Mein altes Headset auch von Plantronics, da verrutschten die Bügel sehr leicht, aber bei diesem Headset sitzen sie fester. Benutze es am PC, mit meinem Bluetooth-Handy und meinem iPad. Hatte Probleme über Bluetooth zu verbinden, aber das lag daran, dass die Bedienungsanleitung nicht sehr ausführlich ist. Hätte mir gewünscht, dass, wie in der Produktbeschreibung angegeben, man das USB Kabel abklinken kann, aber es ist fest verbunden. Der Laut und Leise Knopf hätte größer sein können, aber im Großen und Ganzen bin ich zufrieden. Auf meinem iPad kann ich sogar sehen, ob die Batterie aufgeladen ist und wieviel. Sensoren in den Ohrmuscheln unterbrechen eine Medienwiedergabe sobald das Headset abgelegt wird. Automatische Anrufannahme, wenn man das Headset aufsetzt, gesteuert über die Smart Sensor Technologie. 10 Stunden Betriebszeit, wenn nicht mit PC verbunden. Aufgeladen wird das Headset dann wieder über die USB Verbindung mit dem PC. Weitere zusätzliche Kontrolle über die einzelnen Funktionen erhält man über die Spokes Software, herunterzuladen von Plantronics. Die Bedienungsanleitung erhielt ich auch über Download von Plantronics mitgeliefert wurde nur eine Schnellanleitung. Sobald man etwas verändert, erhält man auch automatische Sprachnachrichten über das Headset, sowie Bluetooth verbunden etc. Ein Mute_ Knopf gibt es auch, mit dem man die Übertragung der Stimme abschalten kann. Ich habe dieses Headset deshalb gewählt, weil das Mikrofon nicht in der Ohrmuschel angebracht, sondern in einem separaten Arm untergebracht ist, der näher am Mund liegt. Man kann mich gut verstehen und es ist auch nicht hinderlich, wie das bei meinem alten Headset der Fall war, wo man das Mikrofon immer aus dem Weg schieben musste, wenn man mal was trinken wollte.

Le ho usate per lavoro e le prendo anche per l'uso privato. Ottimo audio, ben insonorizzate dall'ambiente circostante, polivalenti in quanto utilizzabili collegate direttamente al PC via USB e/o al telebono via Bluetooth. Unico "ma" è il peso, anche se leggere risultano fastidiose indossate per 8 ore di lavoro. Ma non è possibile avere di meglio perlomeno io non ho trovato qualcosa con le stesse permornce.

La calidad del sonido es excelente, además de ligeros, flexibles y cómodos.

Phenomenal headset. It was a big upgrade for me, coming from the C320 and I am glad I made the jump! Audio quality is superb and the noise cancellation is second to none. Bluetooth is a but tricky to get paired but once it's configured it's excellent.

great piece of kit its plantronics so its going to be good comfortable works well with my samsung note2 contacts to computer easily the fob well made precise , if you take important calls this is an excellent headset to have on it wont let you down i also own voyager ,and legend and various others
