How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a featherweight wired headset that disappears on your head during marathon sessions and can tap into virtual surround on PC, choose Razer Kraken X Ultralight; if you need bigger drivers, a wider frequency range, a certified boom mic, and the widest device compatibility, choose ASUS ROG Delta S.
• Razer Kraken X Ultralight — biggest strength: It weighs just 250 grams, making it one of the lightest over-ear gaming headsets you can buy, and it pairs that with a software-enabled 7.1 surround option for PC.
• Razer Kraken X Ultralight — biggest trade-off: The surround sound only works on PC, the 40 mm drivers top out at 20 kHz, and the mic is bendable but not certified by any voice platform.
• ASUS ROG Delta S — biggest strength: 50 mm Essence drivers, a 20 Hz–40 kHz frequency range, and a Discord- and TeamSpeak-certified detachable boom mic cover a lot of ground for voice chat and positional audio.
• ASUS ROG Delta S — biggest trade-off: It weighs 270 grams (slightly heavier), and it relies on passive noise cancellation rather than active.
• Who each pick is for: Pick the Kraken X Ultralight if low weight and PC surround are your priorities; pick the ROG Delta S if you want richer drivers, a certified mic, and broad console/mobile support.
The Kraken X Ultralight is built around one idea: get the headset off your mind. At 250 grams, it's the lightest Kraken Razer has made, and that number matters more than it sounds. If you've ever hit the three-hour mark in a ranked match and felt the top of your skull start to ache, you know the difference a few dozen grams makes. The oval, over-ear cups and plastic frame keep the whole thing airy, and the Mercury White finish is a nice change from the usual black-on-black.
On the audio side, you get custom-tuned 40 mm dynamic drivers with a 32-ohm impedance, 109 dB sensitivity, and a 20 Hz–20,000 Hz range. That's a standard, competent gaming tuning — deep enough for the thump of an explosion, clear enough for footsteps. The catch: the 7.1 surround sound is software-enabled and works on PC only, activated with a download code that comes in the box. On PS4, Switch, or anything else running through the 3.5 mm jack, you're getting straight stereo.
The mic is a bendable cardioid design that cuts down background and ambient noise, and there are in-headset controls — an analog volume wheel and a mic mute switch — so you're not alt-tabbing mid-game. Razer backs it with a 2-year manufacturer warranty.
Buy it if you want the lightest possible wired headset for long PC sessions, you like hardware volume/mute controls within reach, and you play mostly on PC or don't mind stereo on console.
Skip it if you need surround sound on PlayStation or Switch, you want a platform-certified microphone for serious voice work, or you care about extended high-frequency detail — this one stops at 20 kHz.
The ROG Delta S takes the opposite approach: pack in as much audio hardware and compatibility as a 3.5 mm headset can carry. The headline is the exclusive 50 mm ASUS Essence drivers paired with airtight chamber technology, and the numbers back up the ambition — a 20 Hz–40,000 Hz frequency range, which is double the top end of the Kraken X. In practice that means more headroom for fine detail: the treble of a distant reload, the texture of footsteps on gravel. The virtual 7.1 surround runs through Windows Sonic on PC, so no download code needed.
The mic is a real selling point here. It's a detachable boom mic certified by both Discord and TeamSpeak, which is a meaningful signal if you spend hours in voice chat and want to be understood without a separate mic. Detachable also means you can pull it off for music or single-player and turn the headset into plain headphones.
Comfort is handled by a 270-gram frame with ergonomic D-shaped ear cushions in a leather enclosure — that shape is designed to seal better around the ear, which also feeds the passive noise cancellation. Just note the trade-offs: it's a touch heavier than the Kraken X, the isolation is passive only (no active cancellation), and the warranty is 1 year versus 2. The box includes a 3.5 mm audio/mic splitter cable, the detachable mic, and an ROG Hybrid ear cushion set.
Buy it if you want the largest drivers in this comparison, the widest frequency range, a certified detachable mic, and one headset that works across PC, Mac, PS5, PS4, Xbox, Switch, and mobile.
Skip it if absolute minimum weight is your top priority, or you specifically want active noise cancellation.
• Best for all-day comfort and low weight → Razer Kraken X Ultralight (250 g vs 270 g).
• Best for audio detail and headroom → ASUS ROG Delta S (40 kHz top end and 50 mm drivers vs 20 kHz and 40 mm).
• Best for voice chat reliability → ASUS ROG Delta S (Discord- and TeamSpeak-certified detachable boom mic).
• Best for hands-on control without software → Razer Kraken X Ultralight (analog volume wheel and mic mute switch on the headset).
• Best for console and mobile versatility → ASUS ROG Delta S (documented support for PC, Mac, PS5, PS4, Xbox, Switch, and mobile).
• Best for PC-only surround on a budget-minded build → Razer Kraken X Ultralight (software 7.1 via in-box code).
• Best for passive isolation → ASUS ROG Delta S (leather D-shaped cushions and passive noise cancellation).
• Best warranty coverage → Razer Kraken X Ultralight (2 years vs 1 year).
In my opinion, the ASUS ROG Delta S is the stronger all-rounder. The 50 mm Essence drivers, the 20 Hz–40 kHz range, the certified detachable mic, and the broad PC/console/mobile compatibility make it the more capable headset for most people who want one pair to do everything. I'd only steer you to the Razer Kraken X Ultralight if shaving every gram matters to you, if you want hardware volume and mute controls at your fingertips, or if you'd rather have the longer 2-year warranty. If your setup is PC-only and comfort is king, the Kraken X is the smarter pick. For everyone else, the Delta S earns the recommendation.
Both offer virtual 7.1 surround on PC — the Kraken X via a software download code, the Delta S via Windows Sonic. The Delta S has the wider frequency range (up to 40 kHz vs 20 kHz), so it has more headroom for positional detail.
The Kraken X Ultralight is lighter at 250 grams versus 270 grams for the ROG Delta S. The difference is small, but over long sessions the lighter frame can feel less noticeable.
Yes. Its 3.5 mm connector is documented as compatible with PCs, Macs, PlayStation, Nintendo Switch, Xbox, and mobile devices. The Kraken X is aimed primarily at PC, PS4, and Switch.
The ROG Delta S uses a detachable boom mic certified by Discord and TeamSpeak. The Kraken X uses a bendable cardioid mic that reduces background noise but carries no platform certification. For heavy voice-chat use, the Delta S is the safer choice.
