If you want the most controlled, focused audio for calls in a noisy office, choose Plantronics Poly; if you need wireless freedom and a battery that lasts through days of meetings, choose Delton 50X.
• Plantronics Poly — biggest strength: Advanced hybrid Active Noise Canceling with three adjustable settings, plus a noise-canceling boom mic, so you can tune how much of the room you shut out.
• Plantronics Poly — biggest trade-off: It's a corded USB-A headset, so you're tethered to your PC, Mac or desk phone. No wireless roaming.
• Delton 50X — biggest strength: Wireless Bluetooth 5.0 with a claimed 35 hours of talk time and a charging dock, so it keeps going across back-to-back meetings.
• Delton 50X — biggest trade-off: Its noise control is sound isolation plus ENC/DSP on the mic, not adjustable active noise canceling. You get less control over what you hear.
• Who Plantronics Poly is for: Someone parked at one desk who wants the cleanest possible call audio and doesn't mind a cable.
• Who Delton 50X is for: Someone who moves between devices and rooms, wants a dock to drop the headset on, and hates recharging mid-day.
The Blackwire 8225 is a corded, dual-ear (stereo) headset that connects to a PC or Mac over USB-A. The design brief here is noise control on both ends of the call: a noise-canceling boom mic to keep your voice clean, and advanced hybrid Active Noise Canceling with three adjustable settings so you decide how much of the room gets filtered out. If you work somewhere with constant background chatter — an open-plan office, a shared workspace, a home office next to a busy kitchen — that adjustability is the whole point. You're not locked into one level of cancellation.
Comfort details point the same direction: a lightweight build, a padded headband, and 180-degree pivoting speakers so the earcups sit where you need them rather than where the frame decides. It's an on-ear design in black with leather and plastic construction, and it's built around plug-and-play simplicity — connect via USB-A and go. Poly also backs it with a 2-year manufacturer warranty, which is the longer of the two here.
Who should buy it? In my opinion, this is for the person who takes a lot of calls from one fixed setup and treats audio clarity as the priority. The adjustable ANC plus the boom mic is a combination the Delton simply doesn't match on the listening side.
Delton 50X: Who It's For
The Delton 50X takes the opposite approach: cut the cord and outlast the workday. It's a wireless Bluetooth 5.0 headset with a charging dock, and the headline number is battery — 35 hours of talk time and 40 hours of playtime, with a 2-hour charge time and a 10-meter Bluetooth range. For anyone whose calendar is a wall of back-to-back calls, that's the spec that matters most. You drop it on the dock between meetings and stop thinking about charging.
On audio, Delton leans on DSP and ENC to filter ambient noise and keep your voice forward, and the microphone rotates 270 degrees so you can position it properly. Its noise control is listed as sound isolation rather than active noise canceling, so the approach is passive blocking plus mic-side processing — not adjustable cancellation you tune yourself. Worth knowing before you buy if you expected the same "turn the dial" control as the Poly.
Comfort and flexibility are clearly priorities: a soft head cushion, plush ear cushions, and an adjustable headband for different head sizes. It's an over-ear, monaural design in black — so one earcup, not two — with a 30mm dynamic driver. It ships with a charging dock and a USB dongle, works with Windows and Mac computers, laptops, phones, tablets and desktop phones, and Delton covers it with a 1-year manufacturer warranty.
Who should buy it? The multi-device professional who wants one headset for the laptop, the phone and the tablet, plus the convenience of a dock. If wireless range and long battery life are your top two criteria, this is the pick.
Side-by-Side: Which Should You Choose?
• Best for adjustable noise control → Plantronics Poly. Three ANC settings plus a noise-canceling boom mic give you tuning the Delton doesn't offer.
• Best for battery life → Delton 50X. 35 hours of talk time and 40 hours of playtime versus a corded headset that draws from your computer.
• Best for wireless freedom → Delton 50X. Bluetooth 5.0 with a 10-meter range and a charging dock; the Poly is USB-A tethered.
• Best for multi-device switching → Delton 50X. It's built for Windows, Mac, laptops, phones, tablets and desktop phones; the Poly targets PC/Mac and desk phone via USB-A.
• Best for stereo listening → Plantronics Poly. Dual-ear design versus the Delton's single-ear monaural build.
• Best for over-ear comfort style → Delton 50X. Over-ear with plush cushions and an adjustable headband, versus the Poly's on-ear fit.
• Best warranty coverage → Plantronics Poly. Two years versus one.
• Best for a fixed desk setup → Plantronics Poly. Plug-and-play USB-A simplicity with no charging routine at all.
If I had to pick one, I'd buy the Plantronics Poly. In my opinion, adjustable active noise canceling, a dedicated noise-canceling boom mic, stereo sound and a 2-year warranty make it the stronger tool for the thing a headset is actually for: sounding clear and hearing clearly on call after call. The cord is the price of that focus, and for a desk-based worker it's a price worth paying. I'd only switch my recommendation to the Delton 50X if wireless roaming, multi-device pairing and that 35-hour battery genuinely describe your day. Check the current price on Amazon before deciding — the value math shifts depending on what each is going for when you buy.
Yes. The Delton 50X is a Bluetooth 5.0 wireless headset with a 10-meter range and a charging dock. The Plantronics Poly connects via USB-A to a PC, Mac or desk phone, so it stays tethered.
They work differently. The Poly uses advanced hybrid Active Noise Canceling with three adjustable settings plus a noise-canceling boom mic. The Delton 50X uses sound isolation with DSP and ENC on the microphone. For adjustable, tunable cancellation, the Poly is the more capable option.
That's one of its strengths. Delton lists compatibility with Windows and Mac computers, laptops, phones, tablets and desktop phones, and it includes a USB dongle alongside the charging dock.
Delton rates it at 35 hours of talk time and 40 hours of playtime, with a 2-hour charge. The Plantronics Poly has no battery at all since it's corded — it draws power from whatever it's plugged into, so there's nothing to recharge.
