If you want a wired, two-ear headset with dual noise-cancelling microphones for calls and music, choose Yealink UH35; if you need a single-ear headset with USB and 3.5 mm connections for a wider range of devices, choose Yealink UH36-MONO. For flights, my pick between these two is the UH35 when you want both ears covered; the UH36-MONO makes more sense if keeping one ear free matters more.
Yealink UH35 vs Yealink UH36-MONO at a Glance
• Yealink UH35: Its two noise-cancelling microphones, soft memory-foam ear pads, and red busylight suit focused calls. The trade-off: it is USB-wired and does not offer the UH36-MONO’s listed 3.5 mm connection.
• Yealink UH36-MONO: Its single-ear design and USB plus 3.5 mm connectivity give it flexibility across compatible devices. The trade-off: one ear remains uncovered, and its sheet lists a noise-cancelling microphone rather than two.
• Choose the UH35 if you want a two-ear headset for calls and music, particularly at a desk or during a flight where covering both ears is your preference.
• Choose the UH36-MONO if you want to hear more of your surroundings while taking calls or need both USB and 3.5 mm connection options.
The Yealink UH35 is the more natural fit if you want a headset for work calls and music with sound delivered to both ears. Its 35 mm speaker is described as suitable for both, while its two microphones use noise-cancelling technology for conversations. Oval, foam ear pads provide passive noise isolation, so the design aims to soften outside sound without active noise cancellation.
Comfort features include skin-friendly ear pads, soft memory foam, and a leather headband. The headset weighs 139.5 g and has a visible red LED busylight to signal when you are on a call. It is Microsoft Teams certified and is described as compatible with major unified communications platforms, with native integration for Yealink IP phones.

The UH36-MONO is built around a different priority: one-ear listening with wired flexibility. Its listed connections include USB and a 3.5 mm jack, making it the more adaptable choice on paper for compatible IP phones, PCs, tablets, and smartphones. The product information also names a range of Yealink IP phone models; some older models require a specified software upgrade.
For calls, it has a noise-cancelling microphone, passive noise cancellation, and an HD Voice/wideband speaker. Its boom arm bends up to 330 degrees for adjustment. At 200 g, it is heavier than the UH35 according to the listed product information. The sheet describes its wearing style as mono and its ear placement as over-ear, so check that this single-ear format is the kind you want.
I’d choose it for an office or call-center setup where a 3.5 mm option or an open ear is more useful than covering both ears. It is also worth considering if you need to move between compatible device types without relying on USB alone. Skip it if your priority is stereo-style, two-ear listening for music or if a lighter listed weight is important to your decision.
• Best for two-ear listening → Yealink UH35. Its design uses ear pads on both sides, while the UH36-MONO is a single-ear headset.
• Best for a 3.5 mm connection → Yealink UH36-MONO. The UH35 lists USB-C wired connectivity; the UH36-MONO lists USB and a 3.5 mm jack.
• Best for a listed dual-microphone setup → Yealink UH35. It has two noise-cancelling microphones; the UH36-MONO lists one noise-cancelling microphone.
• Best if you want to keep one ear uncovered → Yealink UH36-MONO. That is the clearest practical reason to pick a mono headset.
• Best for a visible call-status light → Yealink UH35. Its red LEDs are designed to make the busylight noticeable during a conversation.
• Best for an adjustable boom → Yealink UH36-MONO. Its boom arm is specified as bendable up to 330 degrees.
• Best for a flight when you want both ears covered → Yealink UH35. Its two-ear design and passive ear-pad isolation fit that preference, although it is not Bluetooth.
• Best for keeping your setup open to nearby sounds → Yealink UH36-MONO. Its mono format leaves one ear free; that is a wearing-style advantage, not a claim of superior microphone or audio performance.
For flights, the difference is easy to picture. The UH35 puts a pad over each ear and is described as having noise-isolating foam pads. That may appeal if you want to focus on audio or a call. The UH36-MONO leaves one ear open, which may suit you if you want to remain more aware of announcements or conversation around you. Neither product sheet describes Bluetooth, a battery, active noise cancellation, or sleep-specific features, so I would not choose either as a wireless sleep solution.
The search for touch control earphones for flights points to a mismatch here: the UH36-MONO’s control information mentions touch, but its listed connection is wired, and the product is presented as a work headset. The UH35, meanwhile, has push-button controls. Neither is described as an ear-clip headphone, so shoppers seeking the best ear clip headphones for flights should look for a different wearing style rather than treating either model as a clip-on option.
I’d buy the Yealink UH35 for flights if I wanted a wired headset with both ears covered, passive isolation, and two noise-cancelling microphones. Its lighter listed weight and red busylight also make it the more appealing fit for my call-focused use.
I’d choose the UH36-MONO instead if I needed its 3.5 mm connection or preferred to keep one ear free. That is a real advantage, but for my flight-focused pick, the UH35’s two-ear design wins.
For two-ear listening, I’d choose the UH35: it has oval foam ear pads and passive noise isolation. The UH36-MONO is the better fit if you prefer one ear uncovered. Neither is listed as Bluetooth.
Neither product sheet lists Bluetooth or a battery; both are wired headsets. They are designed around calls and work use, not described as sleep headphones.
The UH36-MONO lists USB and a 3.5 mm jack for compatible devices. The UH35 is listed as USB-C and wired, so the UH36-MONO is the clearer choice when a 3.5 mm connection is required.
The UH35 lists two noise-cancelling microphones and passive isolation from its ear pads. The UH36-MONO lists a noise-cancelling microphone and passive noise cancellation. Those different descriptions do not establish that one has superior overall noise cancellation.
