If you want secure in-ear workout earbuds with active noise cancelling and a sweat-resistant charging case, choose Amazon Renewed Beats Powerbeats Fit; if you need open-ear awareness, low-latency 2.4GHz gaming audio and a detachable neck strap, choose ASUS ROG Cetra Open. Those two sentences settle most of it. What follows is the reasoning, spec by spec, so you can sanity-check the pick against how you actually listen.
• Amazon Renewed Beats Powerbeats Fit — biggest strength: true in-ear fit with universal secure-fit wingtips, Active Noise Cancelling, Transparency mode, and up to 30 hours total with the case (7 hours per bud).
• Amazon Renewed Beats Powerbeats Fit — biggest trade-off: it seals you off from your surroundings unless you switch to Transparency, and the earbud-plus-case setup weighs more to carry (3.52 ounces for the package).
• ASUS ROG Cetra Open — biggest strength: open-ear design that leaves your ear canal unblocked, dual-mode Bluetooth plus low-latency ROG SpeedNova 2.4GHz, and a 14.2 mm DLC-coated diaphragm driver.
• ASUS ROG Cetra Open — biggest trade-off: up to 16 hours of playtime total, and an open-ear shape that by design lets ambient sound in at all times.
• Pick the Beats if your priority is blocking noise in a gym, on a plane or on a noisy street and you want a wingtip-secured in-ear fit.
• Pick the ASUS ROG Cetra Open if your priority is hearing traffic and teammates while gaming, running or riding, and you want a wired-grade low-latency link to a PC or handheld.
The Powerbeats Fit is built around one idea: staying put. Universal secure-fit wingtips tuck into your ear for stability, and the custom acoustic platform is tuned to deliver balanced Beats sound across the full spectrum. Adaptive EQ goes a step further — it reads each earbud's individual fit and seal and adjusts the audio accordingly, which matters because in-ear sound changes the moment the tip shifts. On top of that you get Personalized Spatial Audio with dynamic head tracking, so the mix repositions as you turn your head.
Noise handling is the headline. Active Noise Cancelling blocks external sound for focus, and Transparency mode flips that around so you can hear your surroundings without pulling a bud out. Both ratings matter here: the earbuds carry IPX4 sweat and water resistance, and the charging case carries an IPX4 rating too — so a wet, sweaty bud going back in the case isn't an obvious problem. Battery is up to 7 hours per bud and up to 30 hours with the case, and Fast Fuel gives up to 1 hour of playback from a 5-minute charge. The case itself is 17% smaller than its predecessor.
ASUS ROG Cetra Open: Who It's For
The ROG Cetra Open takes the opposite approach: it sits outside your ear canal rather than inside it. That open-ear placement is the whole point — you keep ambient awareness while audio plays, which is exactly what you want when gaming on a PC, running on a road, or cycling. Inside, a 14.2 mm DLC-coated diaphragm driver handles crisp highs, deep bass and a spacious soundstage, with Phantom Bass available to push the low end and Immersion Mode to reduce noise when you want to close the gap a little. Frequency range runs 20 Hz to 20 kHz, and impedance is 16 ohm.
The feature that separates it from almost every open-ear bud is connectivity. It runs Bluetooth and low-latency ROG SpeedNova 2.4GHz via an included USB-C dongle — that's a genuinely different use case from a phone-only earbud, because a 2.4GHz link is the kind of thing you want for gaming audio where Bluetooth lag is visible on screen. USB-C passthrough charging powers your phone without interrupting audio, though note the spec sheet's own caveat: it only provides one-way passthrough charging. Battery is up to 16 hours of continuous use, and a 15-minute charge gives 3 hours — that charge time figure is one of the fastest top-ups in this comparison.
Comfort details are thoughtful for active use: soft ear hooks for a secure all-day fit, tactile physical buttons instead of touch surfaces (so a sweaty finger or a glove still works), IPX5 water resistance against rain and sweat, a customizable Aura RGB logo, and a reflective detachable neck strap that prevents drops and adds visibility. It weighs 11.4 grams. Who should skip it: if you want noise cancelling that actually silences a plane cabin or a loud gym, an open-ear bud physically cannot seal — that's not a flaw, it's the design. And if you never game on PC or handheld, you're paying in complexity for a 2.4GHz dongle you won't use.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → Amazon Renewed Beats Powerbeats Fit. Active Noise Cancelling plus a sealed in-ear fit is the only way to genuinely reduce what you hear.
• Best for total battery life → Amazon Renewed Beats Powerbeats Fit. Up to 30 hours with the case versus up to 16 hours.
• Best for fast top-ups → ASUS ROG Cetra Open. A 15-minute charge returns 3 hours; the Beats gives up to 1 hour from a 5-minute charge.
• Best for gaming and low latency → ASUS ROG Cetra Open. ROG SpeedNova 2.4GHz through the included USB-C dongle, which Bluetooth-only buds can't match.
• Best for maximum sweat and rain protection → ASUS ROG Cetra Open. IPX5 on the earbuds beats IPX4, though the Beats also rates its case IPX4.
• Best for losing a bud mid-workout → Amazon Renewed Beats Powerbeats Fit. Wingtips plus an in-ear seal are the more locked-in arrangement for burpees and sprints.
• Best for keeping buds attached without an ear seal → ASUS ROG Cetra Open. Ear hooks plus a reflective detachable neck strap.
• Best for immersive spatial audio → Amazon Renewed Beats Powerbeats Fit. Personalized Spatial Audio with dynamic head tracking and Adaptive EQ.
In my opinion, most people torn between these two should buy the Amazon Renewed Beats Powerbeats Fit. It covers the widest set of everyday jobs — gym, commute, noisy street, long trips — because it's the only one of the two that can actually seal out the world, and 30 hours with the case means you charge it far less often. I'd only steer you to the ASUS ROG Cetra Open if open-ear awareness is non-negotiable, or if you specifically want that 2.4GHz low-latency link for gaming on a PC or handheld. If you fall in that second group, it's the better tool for the job and I wouldn't talk you out of it. Everyone else: the Beats is my pick.
They solve different problems, so "worth it" depends on your ears. The Beats seals and cancels noise with up to 30 hours of case battery; the ASUS leaves your ears open with 2.4GHz gaming connectivity and IPX5. Check the current price on Amazon for both before deciding — this page has a button for that.
Does the ASUS ROG Cetra Open have noise cancelling like the Beats?
The Beats, by a clear margin on paper: up to 7 hours per bud and up to 30 hours with the charging case, versus up to 16 hours of continuous use for the ASUS. The ASUS wins on recharge speed — 15 minutes gets you 3 hours, versus up to 1 hour from 5 minutes on the Beats.
Both. It supports Bluetooth for phones and everyday use, plus low-latency ROG SpeedNova 2.4GHz through the included USB-C dongle for gaming, with USB-C passthrough charging that powers your phone without cutting audio. Just remember the spec sheet notes that passthrough is one-way only.
