How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life and a single-ear headset you can wear all day while jumping between a PC, a phone, and a desk phone, choose Delton Ultralight; if you need a proper over-ear gaming headset with 2.4GHz low-latency audio, per-game sound presets and a real stereo soundstage, choose SteelSeries Arctis Nova 3P.
• Delton Ultralight — biggest strength: an absurd 100 hours of talk time, a charging case, and an auto-pair USB dongle that makes PC connection essentially plug-and-play.
• Delton Ultralight — biggest trade-off: it's a single-ear mono earpiece built for voice, not for immersive stereo gaming or music listening.
• SteelSeries Arctis Nova 3P — biggest strength: 2.4GHz low-latency wireless plus Bluetooth 5.3 in one headset, with 200+ game presets you can tweak from a mobile app.
• SteelSeries Arctis Nova 3P — biggest trade-off: 40 hours of battery is plenty but nowhere near the Delton's, and it's an over-ear headset that costs you head space and a bulkier carry.
• Pick the Delton if your day is calls, meetings and switching between devices.
• Pick the Arctis Nova 3P if your day is games, and headphones double as your PC audio device.
The Delton Ultralight is a communication tool first and a headphone second. It's a single-ear Bluetooth earpiece with a rotating boom mic, an adjustable earband, and three sizes of plush cushions so you can fit it to your left or right ear. That's a design decision, not a limitation to apologize for — it means one ear stays open to the room while the other handles the call. If you work in a shared office, drive, or take back-to-back meetings, that openness is the whole point.
Where the Delton genuinely stands out is endurance and connection flexibility. The spec sheet claims 100 hours of talk time, 90 days of standby, and a 3-hour charge, with Type-C fast charging plus a charging case as a second way to top it up. That combination means you can realistically go a full work week or more without thinking about the charger. The included auto-pair USB dongle is the other quiet win: you plug it into a PC or laptop and you're connected without drivers or software, which is exactly the friction that makes people give up on Bluetooth headsets.
On audio and connectivity, the Delton uses Bluetooth 5.0 with a 10-meter range, a balanced armature driver, and a 20Hz–20,000Hz frequency range with 32-ohm impedance. It connects to two devices at once, so you can take a call on your phone while it's still paired to your computer. The noise-cancelling mic and sound isolation handle the "don't hear my background" job, and touch controls cover volume, track skipping and voice assistant.
SteelSeries Arctis Nova 3P: Who It's For
The Arctis Nova 3P is the opposite philosophy: a full over-ear headset built around gaming, with voice as a secondary concern. It runs on two wireless technologies — a 2.4GHz connection through a multi-platform USB-C dongle, and Bluetooth 5.3 — and you can quick-switch between them. That's a genuinely useful split: 2.4GHz for low-latency gameplay, Bluetooth for music or a phone call without unplugging anything.
The headline feature is the software layer. Through the Arctis Companion mobile app you get 200+ game presets, including dedicated profiles for shooters like Call of Duty and Fortnite, designed to sharpen footsteps, reloads and heals so you can hear opponents before you see them. Whether a preset genuinely makes you better is debatable, but having per-game tuning you can adjust in real time is a real advantage over a fixed-tuning earpiece.
Hardware-wise, the Arctis Nova 3P uses custom neodymium magnetic drivers, 36-ohm impedance, and a frequency response up to 22,000Hz — a wider ceiling than the Delton's 20,000Hz, which matters for music and game soundtracks. It also lists active noise cancellation, which the Delton does not have (the Delton relies on passive sound isolation). Battery is 40 hours, with fast charging that gives up to 9 hours of playback from a 15-minute top-up. At 260 grams with a stretchy headband, multiple adjustment points and a dual-hinge design, it's built to be worn for long sessions without the clamp-and-headache problem.
The trade-offs are real, though. It's over-ear, so it's bulky compared to a pocketable earpiece and its charging case. It's a stereo headset, so it doesn't give you that one-ear-open awareness. And 40 hours, while good for a gaming headset, is a fraction of the Delton's talk time. If your job is calls and you don't game, you're paying for capability you won't use.
• Best for battery life → Delton Ultralight. 100 hours talk time and 90 days standby versus 40 hours on the Arctis Nova 3P.
• Best for gaming audio → SteelSeries Arctis Nova 3P. 2.4GHz low-latency wireless, neodymium drivers, and 200+ game presets via the companion app.
• Best for PC plug-and-play → Delton Ultralight. The auto-pair USB dongle means no drivers and no software; the Arctis Nova 3P also does USB-C plug-and-play, but its value is in the app layer.
• Best for wearing all day at work → Delton Ultralight. Single-ear design, adjustable earband, three cushion sizes, and a rotating mic for either ear.
• Best for music and immersive sound → SteelSeries Arctis Nova 3P. Stereo over-ear drivers with a frequency response up to 22,000Hz and active noise cancellation.
• Best for switching between phone and computer → Delton Ultralight. Dual-device Bluetooth 5.0 connection with one-tap switching.
• Best for long gaming sessions → SteelSeries Arctis Nova 3P. 260g with a stretchy headband and dual-hinge durability, plus 15-minutes-for-9-hours fast charging.
• Best for travel and portability → Delton Ultralight. A compact charging case at 4.5 x 2.5 x 0.9 inches versus a full over-ear headset.
If I had to pick one, I'd buy the Delton Ultralight — but only because my priority is voice-first, all-day wireless with battery I never have to think about. The 100-hour talk time, the charging case, and the auto-pair dongle solve the exact problems that make Bluetooth headsets annoying on a PC. That said, if you game on that same PC, I'd take the SteelSeries Arctis Nova 3P instead. Its 2.4GHz connection, stereo neodymium drivers and per-game presets are simply in a different category for play. Two different jobs, two different answers.
FAQ
Once paired, both work as normal PC audio devices — the Arctis Nova 3P gives you stereo game sound and app-controlled presets, while the Delton Ultralight is a single-ear voice headset with touch controls for volume, track skipping and voice assistant.
Put the headset in pairing mode, open your PC's Bluetooth settings, and select the device. The Delton also lists dual-device connectivity, so it can stay linked to your phone while connected to the computer.
That's where the bundled dongles matter. The Delton Ultralight ships with an auto-pair USB dongle, and the Arctis Nova 3P ships with a multi-platform USB-C dongle, so neither strictly requires your PC to have built-in Bluetooth.
