With this setup, I can use it for any PC software and VOIP calls. **Q: Does this come with the over the ear piece? Does anyone use this versus the headband and is the over the ear piece comfortable?** A: Bogus. The over-ear sucks. That sharp plastic digs into your ear. They need to redesign the plastic piece and make it round, rather than a sharp piece of plastic with a piece of foam over it (that you will lose). I would prefer to be able to style my hair, but I have resorted to the headband. **Q: Does it support Yealink T2 series phones?** A: Not compatible, you can choose WH63 wireless headset from Yealink store **Q: How well are plantronics cs540 wireless dect headset noise cancelling?** A: Quite well, they feature a Noise-canceling microphone that reduces background noise interruptions, ensuring excellent audio quality and easing listener fatigue. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***N on October 25, 2016* ### ⭐⭐⭐⭐⭐ Review *by D***Y on October 20, 2012* ### ⭐⭐⭐⭐⭐ Review *by D***3 on April 23, 2012* ## Frequently Bought Together - Plantronics - CS540 Wireless DECT Headset (Poly) - Single Ear (Mono) Convertible (3 wearing styles) - Connects to Desk Phone - Noise Canceling Microphone - Plantronics - Electronic Hook Switch Cable APP-51 (Poly) - Remote Desk Phone Call Control - Works with Poly Desk Phones --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/1621512-plantronics-cs540-wireless-dect-headset-poly-single-ear-mono-convertible](https://www.desertcart.be/products/1621512-plantronics-cs540-wireless-dect-headset-poly-single-ear-mono-convertible) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-07*
