Overall Impression

The microphone and voice clarity are the headset's biggest strength. Multiple commenters singled out the microphone as excellent and compressed well for online calls, with one reviewer noting it stands out among various Plantronics headsets they've tried. The speaker sound was also praised for precise voice soundstage, making it well suited to WFH or quiet office communication, even though it's not built for audiophile music listening.

Comfort is inconsistent and can become a real problem over time. While one user found the foam earpads comfortable enough for all-day wear after adding textile covers, another reported severe ear pain after just 30 minutes, with colleagues experiencing the same issue. This suggests comfort may vary significantly by user, making it risky for those planning long daily meetings without testing fit first.

Build quality and reliability concerns appear across multiple units. Several users reported hardware degradation or failure, including a headset dying after three months, microphones failing repeatedly across multiple replacement units, and noise cancelling not functioning to block background noise like cars. These recurring reports suggest the 3320 may not hold up as durably as its audio quality would suggest.

micExcellent Microphone Quality

Strongly positive

Commenters repeatedly single out the microphone as a standout strength, describing it as very good and well compressed for online communication. One user compared it favorably against other Plantronics headsets they'd tried.

@falothman

I've tried various Plantronics headsets and totally agree with your comment that this one stands out in the mic quality, which what matters to me most! It's no surprise that it's in the \"Amazon Choice\" list. A small warning though, it's not that fancy build wise and any little damage to cable or material will continue to creep like a tooth decay .. so be gentle. \n\nMine just died after 3 months of use so I ordered another two :)

@AlexMiddleearth

Thanks for review. Your video helped me to make a choice. This is a excellent value for money headset. The microphone sound quality is very good and compressed for online communication. The sound of speakers is excellent for voice very precise voice soundstage and even Ok for music (ambient not audiophile of course). The foam earpads are comfortable but I added soft washable textile earpads covers so I can wear this headset all day long without getting ears sweaty. This why I would rather have velour option than PVC \"leather\". Only thing I do not like is that the microphone is on the right side. Yes you can turn it around but the speakers with remain left and right so stereo will be incorrectly reversed. This is a little of annoying for right handed people because cable is on the right side. But it is good choice for WFH or not very noisy office. Go for Plantronics or Jabra it is worth extra tenner. And good NC headset will improve your online meetings experience.

warningSevere Ear Discomfort

1 mentions

Strongly criticized

One user and their office colleagues reported extreme ear pain after just 30 minutes of use, calling it absolutely poor for comfort during long meetings.

@NEERAJKUMAR-ve4wg

Am I the only one feeling extreme pain with this headset after 30+ mins of use? Most of my office colleagues using this same headset also complained the same. Though sound quality and microphone is very good, it is useless as it will cause very sever ear pain. Absolutely worse in terms of comfort. If you have long meetings, please don't consider buying this.

swap_horizReversed Stereo with Right-Side Mic

Generally negative

The microphone is fixed on the right side, and while it can be rotated, doing so reverses the stereo channels, which one right-handed user found mildly annoying given the cable is also on the right.
