Choosing a headset for your business phone starts with one question: which jack does your desk phone use? The two headsets here answer that differently. One is an RJ9 mono headset built for Yealink VoIP phones. The other is a 2.5mm headset for phones with a 2.5mm headset port. Both are wired, black headsets with noise-cancelling mics, mute switches, and retractable tangle-free cables-but their connectors, conditions, controls, and listed prices split them apart.
Quick Verdict
If your desk phone uses the standard RJ9 headset port, the RJ9 Mono Headset for Yealink Office Phones is the more complete pick. It's new, lists broad Yealink IP and T-series compatibility, and includes volume and mute buttons on the cord. If your phone takes a 2.5mm headset jack, the 2.5mm Noise-Cancelling Headset with Mute Switch is the one that will plug in. It's also the lower-priced option, but you'll be buying an open-box unit.

Where Each Wins
Choose the RJ9 Mono Headset for Yealink Office Phones if you want a new unit with a connector that fits Yealink IP and T-series models like the T46S, T48S, and T5x series. The description adds a 2-year warranty and a 45-day money-back guarantee, which can be reassuring for a desk phone purchase. Choose the 2.5mm Noise-Cancelling Headset with Mute Switch if your phone has a 2.5mm jack and you want the lower listed price. The trade-off is the open-box condition; the listing focuses on the 2.5mm connector rather than specific phone models.
Product Notes
RJ9 Mono Headset for Yealink Office Phones
This headset is built for desks that run Yealink IP and T-series phones. The product description names a long list of compatible models, from the T41S and T46S to the T54W and T57W, and the RJ9 connector is the standard headset plug on many VoIP phones. At USD 38.88, it's the higher-priced option here, but it's a new unit with a dynamic driver, button-operated volume and mute controls, and the same retractable tangle-free cable found on the competitor. The noise-cancelling mic is designed to keep background noise from creeping into calls. The description also mentions a 2-year warranty and a 45-day money-back guarantee, which adds a layer of confidence if you'd rather have that protection. The trade-off is that you'll pay more than the open-box 2.5mm alternative, and you need a phone that accepts RJ9.
2.5mm Noise-Cancelling Headset with Mute Switch
This headset is for phones that use a 2.5mm headset jack. At USD 25.49, it's the lower-priced of the two, and the listing comes from R and J Wares. It has a noise-cancelling microphone, a mute switch, and an in-line controller that handles volume and mute. The cable is retractable and tangle-free, matching the RJ9 headset on that front. The obvious limitation is the condition: this is an open-box unit, not a brand-new one. The listing also centers on the 2.5mm connection instead of naming specific desk phones, so you'll want to confirm your phone uses that jack before ordering. If it does, this is the more budget-conscious way to get a wired headset with the controls you need.
Final Choice by Use Case
For a Yealink IP or T-series desk phone, the RJ9 Mono Headset is the clear match: new condition, broad compatibility, and a listed warranty. For a 2.5mm phone jack and a lower price, the 2.5mm Noise-Cancelling Headset is the practical buy if you're comfortable with an open-box unit.
