• Krysenix's biggest strength: dual-mode wireless with a 2.4GHz dongle for near-zero lag plus Bluetooth 5.4, backed by very long battery life (up to 40 hours with RGB off).
• Krysenix's biggest trade-off: no Xbox support in either mode, and the mic is disabled when you're connected over Bluetooth.
• Black Shark's biggest strength: the widest device compatibility here — PC, PS4, PS5, Switch, Xbox, laptops, tablets, TVs, iPads and phones — plus virtual 7.1 surround and active noise cancellation.
• Black Shark's biggest trade-off: RGB lighting cuts battery life roughly in half (20 hours with lights on versus 40 off), and it weighs 325 g.
• Pick Krysenix if you mainly game on PC or PlayStation and want a light, foldable, travel-friendly headset with a clear mic.
• Pick Black Shark if you need one headset to cover Xbox and TV as well, and you want surround sound and ANC for immersion.
The Krysenix headset is built around one idea: get audio from your device to your ears as fast as possible, wirelessly. It runs 50mm titanium-coated dynamic drivers at 32 ohm, and the headline number is latency of 20 ms or less over its 2.4GHz dongle. That's the figure that matters in shooters — it's the difference between hearing a footstep when it happens and hearing it a beat late. The Bluetooth 5.4 mode is the second half of the pitch: same headset, paired to a phone or tablet for music, videos and casual play.
Battery is where Krysenix quietly wins arguments. The 1200mAh cell charges in about 2.5 to 3 hours and then runs 30–35 hours with the RGB lighting on, or up to 40 hours with it off. For a teen who games after school, does homework with music on, and forgets to charge things, that's close to a full week between top-ups. The over-ear design uses an adjustable headband and soft protein-style leatherette earcups with breathable sponge, and the brand specifically calls out comfort for glasses wearers — a detail that actually matters for long sessions.
The mic is a 120° adjustable boom with noise-cancelling processing, and it's the right tool for voice chat on PC and PlayStation. Two things to know before you buy: it doesn't work with Xbox at all, and the microphone is unavailable in Bluetooth mode — so if your plan is to take calls on your phone, this isn't the headset for that. It's also foldable, which is genuinely useful if it lives in a backpack. The Krysenix is for the PC or PlayStation player who wants low latency, a long battery and a comfortable fit, and who doesn't need Xbox or TV coverage.
The Black Shark Goblin X8 goes the other direction: instead of narrowing the focus, it widens the net. It supports triple-mode connectivity and lists compatibility with PC, PS4, PS5, Switch, Xbox, laptops, tablets, TVs, iPads and phones. If your household has an Xbox in one room and a TV in another, that breadth is the whole reason to pick it. Bluetooth 6.0 with a 10-meter range handles the phone-and-tablet side, and there's a 3.5mm jack as a wired fallback — useful when you want zero wireless variables.
Audio is tuned for immersion rather than pure positioning. It uses 40mm magnetic neodymium dynamic drivers with 39 ohm impedance, a 20Hz–20,000Hz range and 20 ms latency, and it layers virtual 7.1 surround on top. In FPS, RPG and racing games that wider dynamic range is about feeling like you're inside the scene. It also has active noise cancellation, which the Krysenix doesn't — that's a real difference if you game near a TV, a fan, or a noisy house.
The control scheme is genuinely thoughtful: a multi-function button handles volume, mic mute, calls, play/pause and lighting, so you're not reaching for your phone mid-match. The mic is a 120° adjustable, high-sensitivity boom with omnidirectional noise cancellation and a one-touch mute. Comfort is handled with an adjustable ergonomic headband and breathable protein leather cups, though at 325 g it's on the heavier side — something to weigh if a younger teen wears it for hours. Battery runs up to 40 hours, but only 20 hours with the RGB lights on, and a full charge takes about 3 hours through the included cable and manual.
• Best for low latency on PC or PS5 → Krysenix Gaming Headset. Its 2.4GHz dongle delivers ≤20 ms latency without the guesswork.
• Best for device coverage, including Xbox and TV → Black Shark Gaming Headset. It's the only one of the two that lists Xbox support.
• Best for battery life with lighting on → Krysenix Gaming Headset. 30–35 hours with RGB on versus 20 hours on the Black Shark.
• Best for immersive surround sound → Black Shark Gaming Headset. Virtual 7.1 and a wide 20Hz–20kHz range are aimed at scene reproduction.
• Best for blocking out a noisy room → Black Shark Gaming Headset. It has active noise cancellation; the Krysenix relies on passive sound isolation.
• Best for voice chat on PC/PlayStation → Krysenix Gaming Headset. Its adjustable noise-cancelling boom mic works in 2.4GHz mode, but note it's disabled over Bluetooth.
• Best for carrying around → Krysenix Gaming Headset. It folds; the Black Shark doesn't list a folding design.
• Best for lighter wear over long sessions → Krysenix Gaming Headset. No weight is listed for it, while the Black Shark is 325 g.
If I were buying for a teen who games mostly on PC or PlayStation and wants one headset that just works — low latency, long battery, comfortable, folds into a bag — I'd buy the Krysenix Gaming Headset. The 2.4GHz latency figure and the 40-hour battery ceiling are the two specs that decide most real-world sessions, and the mic is there when it counts. I'd only switch to the Black Shark Gaming Headset if Xbox or TV use is non-negotiable, because that's where its compatibility list and virtual 7.1 surround genuinely earn their place. Check the current price on Amazon before you commit — both are worth comparing at whatever they're going for today.
how to connect bluetooth headphones for pc
Put the headset into Bluetooth pairing mode, then open your PC's Bluetooth settings, choose "Add device," and select the headset when it appears. The Krysenix uses Bluetooth 5.4 for phones, tablets and Switch, while the Black Shark uses Bluetooth 6.0 with a 10-meter range. Keep in mind that on the Krysenix, the microphone isn't available in Bluetooth mode.

Pair once, then just power the headset on and it reconnects to your PC automatically for audio playback. For gaming specifically, the 2.4GHz dongle mode is the better route on both headsets because it keeps latency at around 20 ms. Note that the Krysenix dongle mode doesn't support Xbox, and neither headset's mic works over Bluetooth.

Turn the headset on and hold its pairing button until the indicator flashes, then add it from your computer's Bluetooth menu. Both headsets support this, and the Black Shark also gives you a 3.5mm wired option plus USB and USB-C adapters for its transmitter. The Krysenix charges over USB-C.

If pairing fails, remove the old entry from your PC's device list and start the pairing process again from scratch. Make sure the headset isn't still connected to a phone, since most models only hold one active Bluetooth link at a time. For the lowest-latency PC gaming experience, skip Bluetooth entirely and use the 2.4GHz dongle on either headset.
