Plantronics Backbeat Fit 3100 True Wireless Earphones $98 @ Officeworks


Please note, these are purposefully designed with poor noise isolation

These Plantronics BackBeat Fit 3100 Wireless Earphones feature a waterproof construction so you don't have to worry about damage from moisture if you sweat or get caught in the rain. They're designed to provide a comfortable and stable fit even if you're running or exercising.

  • The earphones connect to your devices via Bluetooth so you won't have cables getting in the way.
  • You can use the Always Aware feature to hear some background noise, helping you to stay aware of your surroundings while you listen.
  • The earbud design wraps around your ear to help hold it in place.
  • You can use the BackBeat app to customise your listening experience.
  • These earphones feature a black design.
  • They provide up to 5 hours of power before you'll need to recharge.
  • There's a microphone built-in so you can also use the earphones to take handsfree calls.

  • I purchased these about a year ago, they were ok but I found they would lose connection in 1 ear for like a second whenever there was the slightest interference between my phone and the headphones (like often just having my phone in my bag or pocket)

    Never had this problem with my galaxy buds, so I was pretty disappointed with the Plantronics

    • What phone were you using?

      • Had a galaxy note 9. Which I've had about a dozen different bluetooth headphones connect to over the past 2.5 years. Theses were the only headphones to ever had issues.

        I also have the 2100, and they work fine.

    • Return them to Officeworks and they'll swap it over straight away for a new pair (if under 12 months). Officeworks are great for returns or replacements.

      • Purchased them from JB, only had them for about 4 months and then I lost them so never got a chance to return them. Sounds like squomas below had similar issues

    • I have had for about 6 months using 3 times a week for runs and have had them disconnect twice. Both times I just reset them and they reconnected.

  • I went through two pairs of these from Harvey Norman around 12-18 months ago. There was a persistent background hiss at low volumes, let alone any occasional bluetooth drop out. Returned for a refund.

    Disappointing after my older Plantronic headphones are rock solid (https://www.ozbargain.com.au/node/194712).

  • The 3100 was the first Poly made in this style and… they're okay. I've had mine for about 18 months and they still fail every now and then but not yet enough to replace them.
    Newer models were introduced in 2019 https://www.cnet.com/news/plantronics-releases-3-new-true-wi...


    Contacted the CS team, they wouldn't do anything about it, just asked me to return it but is a product issue.

  • I bought these about 18 months ago, they were the only non-isolating Bluetooth earbuds i could find (that didn't appear too cheap). Never had a problem with them, the only complaint I can make is that the charger sometimes makes a high pitch sound when charging - noticeable if you're sleeping in the same room as the charging earbuds :D

  • These work by making one earpiece the 'primary' which connects to your phone. The secondary earpiece connects to the primary one.

    They are prone to interference, usually making the secondary earpiece drop out. I eventually realised they would always drop out when I approached traffic lights in Melbourne CBD - the lights must send radio signals when they change, which impacts the connection between the earphones.

    I generally don't have issues with them elsewhere, ie travelling on the train or walking in the 'burbs.

  • Sounds like some ppl have issues. I don't so it may be largely dependent on the phone being used. fwiw using a Huawei mate 20!

  • These are garbage. Got them for Christmas, tried to persist with them but I can't stand it anymore. Connection drops out intermittently (Pixel 3). Volume is so low and so much noise due to poor isolation I can barely hear on max volume (while running or cycling). They're uncomfortable and don't come with different buds to ensure a good fit.

    • I had the same experience. I bought at JB Hifi. They kindly obliged, when I mentioned the reason why i did not like them and want to upgrade to plantronics backbeat fit 3200 which has good noise isolation like the other usual true wireless earphones.

      I suggest to try the same.
