• targeal USB C — biggest strength: A wired USB-C connection with a detachable boom microphone, 7.1 surround processing, and on-cable mute and volume controls. Built for talking and gaming, not for the gym.
• targeal USB C — biggest trade-off: It's wired, in-ear, and the mic is a physical boom you attach. No Bluetooth, no battery, and the warranty is short at three months.
• Sudio B2 — biggest strength: Open-ear bone conduction that leaves your ear canals free, so you stay aware of your environment while cycling, running or commuting. 7.5 hours of playtime and IPX5 water resistance.
• Sudio B2 — biggest trade-off: Open-ear sound leaks and won't isolate you from noise at all, and there's no noise control of any kind. It's made for movement, not for competitive gaming.
• Who each pick is for: Pick targeal USB C if your priority is clear voice chat and immersive game audio on a phone, console or PC. Pick Sudio B2 if your priority is staying alert and tangle-free while you're active outdoors.
The targeal USB C is a purpose-built gaming earphone. It connects over a wired USB connection, which in practice means no pairing, no charging and no wireless latency between what happens on screen and what you hear. For anyone who's ever lost a firefight because their Bluetooth buds lagged half a beat behind the action, that's the whole point.
The detachable microphone is the standout feature here. Instead of a tiny mic buried in the earbud housing, you get a boom you can bring closer to your mouth — and the design is explicitly aimed at reducing background noise while improving voice pickup. In my opinion, that positioning flexibility is what separates a real headset from earbuds pretending to be one. The in-ear design also helps: because the silicone tip seals your ear canal, you get isolation from room noise rather than fighting it. It ships with S/M/L caps so you can find a decent seal, and the aluminum housing gives it a more substantial feel than plain plastic.
On the audio side, targeal lists a 10 mm dynamic driver covering 20 Hz to 20,000 Hz, with 7.1 surround sound processing, and hybrid noise cancellation for the listening side. The on-cable remote handles volume and mute, which is exactly what you want mid-match — no reaching for your phone.
Who should buy it: mobile gamers, Switch, Xbox One, PlayStation and PC players who want one wired headset that works across all of them, plus anyone who takes voice chat seriously. The compatibility list is genuinely broad, spanning Galaxy, OnePlus, Pixel, MacBook Pro and iPad.
Sudio B2: Who It's For
The Sudio B2 takes the opposite approach entirely. It's an open-ear, bone conduction headphone — sound travels through your temples rather than pumping into a sealed ear canal. Nothing blocks your ears. That single design choice defines everything about it.
The practical benefit is situational awareness. If you cycle, run, walk busy streets or just want to hear a colleague call your name, this is the design that lets you do it. Sudio lists it at 29 g with what the brand calls "lagom tension" in the band — Swedish for just the right amount — so it's built to sit around your head without clamping. That low weight matters over a long day; it's the kind of thing you forget you're wearing.
Sound is described as airy and transparent, with a bone conduction driver covering 20 Hz to 20,000 kHz, and spatial sound processing. Be honest about the trade-off: bone conduction doesn't isolate. You will hear the world, and the world will hear a little of your audio. There's no noise control at all — the spec sheet says "None." That's not a flaw, it's the deal you make for awareness.
Battery life is up to 7.5 hours at 50% volume, recharged in about 1.5 hours over USB-C, with Bluetooth 5.3 and a 10-metre range. IPX5 means it shrugs off rain and sweat. Controls are physical buttons — play/pause in front of the ear, secondary functions behind it — and the omnidirectional microphones pick up your voice from multiple directions, which is a better arrangement for calls on the move than a single fixed mic.
Who should buy it: commuters, cyclists, runners, gym-goers and anyone who wants headphones that disappear into their day. Who should skip it: gamers who need positional audio and a boom mic, and anyone who wants to shut the world out on a flight.
• Best for competitive gaming and voice chat → targeal USB C. Wired connection, 7.1 surround, detachable boom mic, on-cable mute.
• Best for running, cycling and commuting → Sudio B2. Open-ear design keeps you aware of traffic; IPX5 handles sweat and rain.
• Best for cross-platform console and PC use → targeal USB C. Its compatibility list covers Switch, Xbox One, PS and PC plus a wide range of phones and tablets.
• Best for all-day comfort at low weight → Sudio B2. At 29 g with a tension-tuned band, it's designed to be worn for long stretches.
• Best for zero-latency, zero-charging reliability → targeal USB C. A wired USB connection never needs a battery and never drops out.
• Best for wireless freedom → Sudio B2. Bluetooth 5.3 with a 10-metre range and 7.5 hours of playtime, recharged in 1.5 hours.
• Best for hearing your surroundings → Sudio B2. Open-ear bone conduction is the entire point of the design.
• Best for blocking out a noisy room → targeal USB C. Sealed in-ear tips plus hybrid noise cancellation on the listening side.
If I had to pick one, I'd buy the targeal USB C — for the simple reason that it does a job most earbuds can't: a wired, low-latency connection with a microphone you can actually position. If your main use is gaming and voice chat, that combination is worth more than wireless convenience.
But I'd recommend the Sudio B2 without hesitation to a different person entirely — the runner, the cyclist, the commuter who needs to hear the world. These two aren't really competing for the same buyer. Buy the targeal for the desk, the console and the match. Buy the Sudio for the pavement.
targeal USB C, clearly. It's wired, so there's no Bluetooth latency, it supports 7.1 surround sound, and it has a detachable boom microphone with on-cable mute. The Sudio B2 is an open-ear wireless headphone with no gaming features and no noise isolation.
Can I use Sudio B2 for phone calls?
No — and that's intentional. The spec sheet lists noise control as "None." Bone conduction sound travels through your temples, leaving your ear canals open, so you stay aware of your environment. If you want isolation, the targeal's sealed in-ear tips with hybrid noise cancellation are the better fit.
Yes, but differently. The targeal USB C connects over a wired USB-C connection and lists broad compatibility across Galaxy, OnePlus, Pixel, iPad and MacBook Pro. The Sudio B2 connects wirelessly over Bluetooth 5.3 with a 10-metre range. If your phone still has a 3.5 mm jack, note the Sudio B2 also lists a 3.5 mm jack connection.
