If you want a plug-and-play headset for softphones on a computer, choose MKJ USB-A; if you need a headset for a physical desk phone with an RJ9 port, choose EAGATON X1. These two are not really rivals in the traditional sense — they solve different problems. One is built around USB audio for softphone apps like Teams, Zoom and Webex. The other is built around a 4-pin RJ9 connector for Yealink, Cisco, Polycom and Avaya desk phones. Buying the wrong one is the single biggest mistake people make in this category, so let's break down exactly who each one fits.
• MKJ USB-A biggest strength: USB plug-and-play for computer-based calling, with a passive noise-cancelling boom mic, in-line volume and mute controls, and a binaural (dual-ear) design.
• MKJ USB-A biggest trade-off: It's a USB-only headset — it will not connect to a traditional desk phone, and it's on-ear rather than over-ear.
• EAGATON X1 biggest strength: Purpose-built for desk phones with an RJ9 connector, single-ear awareness design, and a pro noise-cancelling boom mic tuned for speech.
• EAGATON X1 biggest trade-off: Desk phone only — it will not work with a computer, laptop, tablet or smartphone, and the drivers are tuned for calls, not music.
• Who MKJ USB-A is for: Remote workers, call center agents and office staff who take calls through a computer via Teams, Zoom, Webex, Jabber or similar softphones.
• Who EAGATON X1 is for: Call center agents, receptionists and front-desk staff who take calls on a physical IP desk phone and want one ear free.
The MKJ USB-A is a wired USB headset with a dual-ear (binaural) on-ear design. Its whole identity is built around the computer. It plugs in via USB, works with Windows XP through Windows 10 and Mac, and is compatible with the big UC softphone platforms — Skype for Business, Microsoft Teams, Zoom, Cisco Jabber, 3CX, Webex and others. If your calls live inside an app window, this is the headset that makes sense.
The microphone is the headline feature. It's an advanced noise-cancelling boom mic that, per the manufacturer, reduces up to 85% of background noise and uses DSP for clear voice transmission. The flexible boom arm adjusts to your mouth position, which matters if you're in a noisy home office or a busy floor. Audio comes from dynamic drivers with a 30 ohm impedance, a 50 Hz–20 kHz frequency range and 100 dB sensitivity.
Comfort is aimed at long shifts. The headband adjusts for different head sizes, the ear cushions are large protein leatherette, and the whole thing weighs about 6.87 ounces. There's an in-line controller for quick volume up/down and one-touch mute — useful when you need to cough or sneeze mid-call without fumbling for software buttons. Durability gets attention too: the reinforced cord is designed to survive office chair wheels and the usual desk abuse.
Who should buy it: Anyone whose calls run through a computer — remote workers, help-desk staff, online teachers, and call center agents on a softphone platform.
Who should skip it: Anyone whose calls come through a traditional desk phone. There's no RJ9 connector here, so it simply won't plug in. Also skip it if you specifically want a single-ear design to keep one ear open to the room.
The EAGATON X1 is a different animal entirely, and the manufacturer is refreshingly blunt about it: this is a desk phone headset. It uses a 4-pin RJ9 connector and is designed exclusively for desk phones. It will not work with computers, laptops, tablets or smartphones. If you're shopping for a USB headset, stop here — this is not it.
What it does well is the physical phone. It's a single-ear (mono) design, which is the classic call center and receptionist setup: one ear on the call, one ear on the room. That awareness matters when a teammate taps your shoulder or a customer walks up to the front desk. The ear cushion is ultra-soft PU leather with a ventilated design, paired with an adjustable headband, and it's built for 8+ hour shifts without ear fatigue.
The microphone is a flexible uni-directional boom mic with noise cancelling, tuned to filter out office chatter, keyboard clicks and AC hum. The drivers are calibrated for speech clarity rather than full-range music — the maker says outright that rich, immersive sound for music, movies and gaming isn't achievable here. That's an honest trade-off, not a flaw. Audio specs include a 28 mm dynamic driver, 150 ohm impedance and a 20 Hz–20 kHz range.
Who should buy it: Call center agents, receptionists, front-desk staff and anyone on a Yealink, Cisco, Polycom or Avaya IP desk phone who wants one ear free.
Who should skip it: Anyone taking calls through a computer, and anyone who wants to listen to music or game on the same headset.
Side-by-Side: Which Should You Choose?
• Best for computer-based softphone calls → MKJ USB-A. USB connection, UC platform compatibility, dual-ear design.
• Best for physical desk phone calls → EAGATON X1. RJ9 connector with three adapters for different phone brands.
• Best for keeping one ear open to your surroundings → EAGATON X1. Mono single-ear awareness design.
• Best for full focus on the call → MKJ USB-A. Binaural design blocks out the room and keeps both ears on the conversation.
• Best for on-device controls → MKJ USB-A. In-line volume and one-touch mute without touching the software.
• Best for call-only audio tuning → EAGATON X1. Drivers calibrated for speech intelligibility, not music.
• Best for a reinforced, chair-wheel-resistant cable → MKJ USB-A. The cord is specifically built for office wear and tear.
• Best for longer shift comfort with a lighter clamp feel → EAGATON X1. Ventilated PU leather cushion and headband designed for 8+ hour shifts.
My Verdict
No. It's an RJ9 headset designed exclusively for desk phones and won't work with computers, laptops, tablets or smartphones. For computer-based calling, you need a USB headset like the MKJ USB-A.
No. It connects via USB only, so it's meant for computers and softphone platforms like Teams, Zoom and Webex. It won't plug into a traditional desk phone's RJ9 port.
Not really. The drivers are tuned for speech intelligibility during calls, and the manufacturer notes the immersive sound needed for music, movies and gaming can't be achieved with this headset.
