Poly (Plantronics + Polycom) CS540 Wireless Headset System Review

In today's fast-paced business world, clear and effective communication is essential. Whether you're working in a hectic office or remotely, staying connected with crisp audio quality is key. The Poly (Plantronics + Polycom) CS540 Wireless Headset System aims to deliver an unparalleled communication experience, thanks to Plantronics' expertise in wireless headsets and Polycom's proficiency in audio conferencing. So, does this headset system live up to the hype? Let's dive in and find out.

Design and Comfort:

The first thing that caught our eye about the CS540 is that it's the lightest DECT wireless headset currently available in the market. Weighing only 22 grams, you can wear it for an extended period without any discomfort. The CS540 comes with a choice of three customizable and comfortable wearing styles- Over-the-head, Over-the-ear, and Behind-the-neck. Personally, we found the over-the-ear option ideal for extended use, providing a secure fit without needing constant adjustment. Moreover, the headset's magnetic docking system is a well-thought-out feature, making charging effortless and keeping the headset secure when not in use.

Wireless Range and Battery Life:

The Poly CS540 headset system boasts an impressive wireless range of up to 350 feet, giving you the freedom to move around without dropping calls or compromising audio quality. This range is undoubtedly a game-changer for those who like to multitask or work in noisy environments. However, it's worth noting that certain environmental factors can impact wireless range, such as building materials or electronic equipment.

We also found the battery life to be impressive, with a talk time of up to 7 hours on a single charge. The headset's intelligent energy-saving feature turns off the power for inactive headsets automatically, maximizing battery life. While the battery life could be improved further, 7 hours should suffice for most workdays.

Audio Quality:

The Poly (Plantronics + Polycom) CS540 Wireless Headset System excels when it comes to audio quality. The headset features a noise-canceling microphone that reduces background noise, allowing you to communicate clearly even in loud environments. It is an excellent feature for those who have to make calls in a crowded office or via a mobile phone. Additionally, the CS540 comes with Digital Signal Processing (DSP), which enhances audio clarity by suppressing sudden loud noises like echoes, providing a premium audio experience.


The Poly CS540 headset system connects to office desk phones, making it an excellent choice for professionals who spend considerable time on the phone. The headset features a DECT 6.0 wireless technology, meaning audio connects wirelessly to the desk phone through a base system provided with the package. The base system is easy to set up, and once connected, the audio quality did not skip a beat. The headset's ability to connect wirelessly to the base system provided seamless freedom for us to walk around our office while still maintaining the audio connection.

Customer Reviews:

So what do customers think about the Poly CS540 headset system? The product currently has an impressive 4.2 out of 5 stars rating, backed by 110 customer reviews on Amazon. Customers were impressed by how light the headset was, the audio quality, battery life, and wireless range. However, some customers had connectivity issues, while others found the earpiece to be slightly uncomfortable.


Overall, the Poly (Plantronics + Polycom) CS540 Wireless Headset System is an excellent choice for professionals who rely heavily on clear communication. Its lightweight design, comfortable fit, impressive wireless range, and excellent audio quality make it a standout performer in the market. While it's not perfect, with connectivity and comfort issues noted by some customers, it's a small price to pay for such an excellent wireless communication headset. If you're looking for a top-notch wireless headset system, we highly recommend the Poly CS540.
