Customer Reviews

Blackwire C420-M MOC Headset-DISCONTINUED is rated 4.2 out of 5 by 5.
Rated 5 out of 5 by from Mini review of 420-m Excellent, but not for long use it starts to tighten your ears after 3-4 hours, for additional comfort take Blackwire 620 they can be held all day long!!

Rated 2 out of 5 by from Squeals due to faulty volume control After one year the unit developed a squeal that could only be fixed by twisting laterally the volume control. I only assume that the circuitry inside the volume/call control mechanism is manufactured poorly and the plastic housing does not support or protect it well. Poorly made. Original unit worked well and it is comfortable to wear.

Rated 4 out of 5 by from Great value for the money! Our company is connected globally using Skype for Business. These headphones make communication easy while using your laptop. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Plantronics headsets This the third Plantronics head set I have purchased. I travel extensive and use the headset with Skype and other VOIP's. This head set is not as good as my previous two head sets. It is big and bulky, it does not pack well, but it works ok. The previous head set simply were worn out from all the use, good product.

Rated 5 out of 5 by from Awesome for conference calls I bought this headset to use durin conference calls at work, and boy do they work well! They block out a lot of outside noise and you can clearly hear everyone on the other lines. I also like the volume, mute, and hang-up buttons. Highly recommend this product. My co-workers are now ordering some for themselves!!
