What's in The Box
Product Overview

Plantronics/Poly CS520 Wireless Headset

The latest CS520 is for use with an office phone only and comes as a binaural wireless headset (the headset has two ear cups) and that puts it in a very unique class - there are very few binaural wireless headsets available. Manufacturers’ actually suggest that if you spend more than 4 hours a day on the phone, you should use a binaural model. The reason is twin ear cups offer a less fatiguing listener experience, since the sound is distributed equally between the ears so the volume doesn’t need to be as loud.

If you’re looking to answer calls away from your desk you'll need a HL10 handset lifter or an Electronic Hook Switch depending on the phone you have (call our friendly staff for assistance). This device fits on your telephone base and lifts the hand piece up or down when you push a button on your headset, letting you answer and hang up on calls from anywhere in the office. A handset lifter for this headset is available separately, or as a great value pack.

So let’s start by reviewing.

What is Poly? Plantronics + Polycom have merged to create Poly

The Good

The Plantronics/Poly CS520 is the work horse of the 500 series. It is truly a case of function over form. It offers great talk time, a robust build design and it’s even more comfortable being 2 ears.

The sound quality in the new CS520 headset is superb and incorporates their Enhanced Digital Signal Processing (DSP) technology which is claimed to deliver more natural voice sounds. Plantronics/Poly have also cleverly incorporated a new Voice-dedicated DECT™ technology which means that it eliminates interference from wireless networks you may have in the office. As more office devices become wireless this may become important.

The Plantronics/Poly CS520 also offers users noise cancelling. This eliminates much of the background noise in a regular office and really is a must. You can also now conference in other headset users (up to 3). This is a brilliant feature in call centres and where a manager may need to get on the line. Plantronics/Poly has also given the CS 520 an intelligent adaptive power system that increases or reduces power consumption, based on your distance from the base station. This extends battery life and gives you up to 9+ hours talk time so it won’t run out during the day!

The Plantronics/Poly CS520 wireless headset also features the “must have” SoundGuard technology. This protects phone users from loud, potentially harmful noises. This happens when ‘acoustic shocks’ are transmitted down phone lines as a result of dangerous customers yelling, blowing whistles, electricity spikes, weather conditions, transmission faults and the like. Without a feature like this there have been reported cases of people suffering from temporary, even permanent hearing loss. Plantronics/Poly SoundGuard means you’ll be protected whenever you are using your CS 520 headset.

The Not-So-Good

The main downfall of all office-only wireless headsets like the Plantronics/Poly CS520 is they only work with your office desk phone. The future of headsets is moving towards voice and computer convergence. This simply means that more people will start to use their headsets for softphone IP applications, VoIP (like Skype) and voice recognition software like Dragon Speak 11 and MacSpeech. Products like the CS520 are simply one trick ponies – which is perfect of that’s all you want.Many people are buying unified communications or multi-use headsets (computer +office phone) to keep their options open. If convergence is in your future, then pay a little more to cover your bases now rather than having to replace your headset down the track.

The Verdict

For office only phone applications the Plantronics/Poly CS520 is a smart buy for Plantronics/Poly fans as nearly every other binaural model offers unified communications but this comes at a slight premium in price, with one notable exception....

Other Headsets You Should Consider Before Buying

The best quality phone only binaural wireless headset is the DW Pro 2 Phone, which for just a few extra bucks is without doubt the superior choice.

Look at the prices difference for yourself and you may find for just a little more the Savi W720 (office + computer + mobile) or the brilliant Sennheiser DW Pro 2 (office + computer)may be the better buys and future-proof your purchase. If sexy technoloty is your thing, have a look at the Jabra Pro 9465. For what all of these headsets offer you really do get a whole lot more.

    I have been using this headset for approximately 4 years now (have replaced once with same model in this time) and am shopping for replacements again. I would say this unit was fine for the first 2 years, then its battery life well and truly disappeared and I'm lucky to get 30 mins of talk time before it is flat. I have NEVER enjoyed 9 hours of talk time. On very busy days when it was new, I would get about 3 hours talk time max. Heading back to a corded option..

    I am currently using the 2 ear model and find the sound quality excellent, it also has the added benefit of blocking out a lot of background noise in our vibrant communal office. This morning I set up my desk in a much more ergonomic manner as I am no longer restricted by my corded phone.

    The headsets are great.

    The recipients in the office are much appreciative of the headsets because they are able to use their computers fluently while on the phone, and they don’t get neck fatigue from cradling the handpiece between the shoulder and the head.
