If you want a true gaming headset with huge 50mm drivers, three ways to connect and a 100-hour battery, choose acer 2.4GHz; if you need a featherweight single-ear headset built for all-day calls on Zoom, Teams and your phone, choose Delton Ultralight.
• acer 2.4GHz – biggest strength: a full over-ear gaming package — 50mm dynamic drivers, 2.4GHz transmitter plus Bluetooth 5.3 plus a 3.5mm jack, and a claimed 100 hours of playtime.
• acer 2.4GHz – biggest trade-off: it's a bulky 350g over-ear headset with a 4-hour charge time, so it's not something you'll want to wear around the office all day.
• Delton Ultralight – biggest strength: an in-ear monaural earpiece at just 1.9 ounces, with DSP noise cancellation on the mic and a claimed 100 hours of talk time.
• Delton Ultralight – biggest trade-off: Bluetooth 5.0 only, no dongle or wired option listed, and a single earbud means no stereo immersion for games or music.
• Who each pick is for: acer 2.4GHz for PC and PlayStation gamers who want immersive sound; Delton Ultralight for remote workers and road warriors who live on calls.
The acer 2.4GHz headset is, first and foremost, a gaming product. The spec sheet leads with a 100-hour battery life and a quick-charge feature, and the 50mm dynamic drivers sit in dual acoustic chambers — that's a big driver for the money-or-anything class of gaming headset, and it's the part of the design that matters most if you care about hearing footsteps, distant gunfire and positional detail rather than just a voice in your ear.
Connectivity is where this headset earns its keep. You get Bluetooth 5.3, a 2.4GHz wireless transmitter for plug-and-play low-latency use, and a 3.5mm jack as a wired fallback. Acer lists a 22ms audio latency figure and a 10-metre (roughly 32-foot) wireless range, plus a frequency range of 20Hz–20,000Hz and 96dB sensitivity. In practice that means you can run it wirelessly on a PS5 or PS4, drop to the 3.5mm cable on a controller or PC when you want zero lag, or pair it over Bluetooth with a phone or laptop. The noise-cancelling mic is designed to filter background noise so your teammates hear commands, not your room.
Buy it if you game on PC, PS4 or PS5 and want one headset that covers wireless, 2.4GHz and wired. Skip it if you need something tiny for back-to-back work calls — this is a gaming rig, not a commuter earpiece.
Delton Ultralight: Who It's For
The Delton Ultralight is a different animal entirely. It's a monaural in-ear Bluetooth earpiece — one bud, 13mm dynamic driver, 32 ohm impedance, 114dB sensitivity and a 20,000Hz frequency ceiling. It weighs 1.9 ounces in total and ships with a carrying case and stand, which tells you the design intent: this is a headset you keep in a bag and pull out for calls, not one you sit down with for a four-hour raid.
The feature set is built around voice, not music. Delton uses DSP (Digital Signal Processing) with electronic noise cancellation to isolate your voice and cut background noise, and the rotating microphone can be angled to the right spot. Controls are touch-based via a call-control scheme with volume adjustment, a pause button and a multi-functional button — the kind of layout you learn in five minutes and then use without looking.
Battery is the headline number: 100 hours of talk time, 110 hours of playtime and up to 90 days of standby, recharged over Type-C fast charging. Bluetooth 5.0 handles the connection with a listed 30-foot range, and Delton says it works across Google Meet, Zoom, WhatsApp, Skype and similar platforms, plus phones, tablets, Windows and Mac PCs, desktops and Bluetooth desktop phones.
Buy it if your day is calls, meetings and voice chat, and you want something you barely feel on your ear. Skip it if you want stereo sound, gaming immersion or a wired option — none of that is here.
Side-by-Side: Which Should You Choose?
• Best for all-day comfort on calls → Delton Ultralight. 1.9 ounces and an in-ear bud versus 350g of over-ear hardware is not a close contest.
• Best for connection flexibility → acer 2.4GHz. Bluetooth 5.3, a 2.4GHz transmitter and a 3.5mm jack give you three paths; Delton offers Bluetooth 5.0 only.
• Best for battery life → a tie on paper. Both claim 100 hours, though acer frames it as playtime and Delton as talk time plus 90 days of standby.
• Best for charging speed → Delton Ultralight. Type-C fast charging against a 4-hour charge time on the acer.
• Best for voice clarity in noisy rooms → Delton Ultralight. DSP electronic noise cancellation is the whole point of this earpiece.
• Best for working across Zoom, Teams-style platforms and phones → Delton Ultralight. That's its stated compatibility list; the acer is positioned around PC and PlayStation.
• Best for low-latency wireless gaming → acer 2.4GHz. The 2.4GHz transmitter and listed 22ms latency exist precisely for that.
If I had to pick one, I'd buy the acer 2.4GHz — but only because my use case is gaming. Three connection types, 50mm drivers, memory foam cushions and a 100-hour battery make it the more versatile device for anyone who plays on PC or PlayStation. If your primary job is talking on calls all day, the Delton Ultralight is the smarter, lighter, more focused tool, and I'd recommend it without hesitation for that. Decide what you actually do most, then check the current price on Amazon before you commit.
FAQ
That's exactly what it's designed for. Delton lists compatibility with Google Meet, Zoom, WhatsApp and Skype, plus phones, tablets, Windows and Mac PCs. The DSP noise cancellation and rotating mic are aimed at voice work.
Both are rated at 100 hours, so on paper it's a wash. The difference is how they charge: the Delton uses Type-C fast charging, while the acer lists a 4-hour charge time with a quick-charge feature.
For calls, the Delton Ultralight — it weighs 1.9 ounces and sits in one ear. For gaming, the acer's memory foam cushions and adjustable headband are built for marathon sessions, though at 350g it's noticeably heavier to wear.
