How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lighter, sweat-proof sport earbud with active noise cancellation and a smart battery display, choose chalvh Ear buds; if you need maximum total playback time and the newest Bluetooth version, choose Faxoimu Earbuds.
• chalvh Ear buds — biggest strength: Active Noise Cancellation plus IP7 waterproofing in a 3 g per-bud design, with Bluetooth 5.4 rated for a 15 m range and 100 ms latency.
• chalvh Ear buds — biggest trade-off: 50 hours of total playback and 8 hours per charge is solid, but it trails the Faxoimu case by a wide margin on total runtime.
• Faxoimu Earbuds — biggest strength: Bluetooth 6.1 and a 950 mAh charging case that extends playback to a claimed 120 hours, with a dual LED battery display.
• Faxoimu Earbuds — biggest trade-off: No active noise cancellation mentioned, and call time drops to roughly 3–4 hours, so heavy talkers will be charging often.
• Pick chalvh if you run, sweat, want noise cancelling, and prefer touch controls.
• Pick Faxoimu if you want the longest possible time between charges and the newer Bluetooth generation.
The chalvh Ear buds are built around a sport-first idea. Each bud weighs just 3 g, and the shell uses a curved in-ear structure with soft ear hooks (arches) meant to hold the bud in place through movement. In my opinion that combination — light weight plus a hook — is exactly what you want if regular in-ear buds tend to slip out mid-run or mid-set. The IP7 nano coating adds sweat and rain resistance, which lines up with the running-and-gym pitch.
On the audio side, chalvh uses 14 mm titanium-diaphragm dynamic drivers with AAC and SBC encoding, covering a 20 Hz–20,000 Hz range. That's a conventional but sensible setup for wireless earbuds — titanium diaphragms are typically chosen for a stiffer, quicker-moving surface, which usually translates to tighter bass and cleaner treble than a basic plastic driver. The spec sheet also lists Active Noise Cancellation as the noise-control method, which is the single biggest functional difference between these two products. If you commute, fly, or work in a noisy room, that matters more than any other number here.
The other half of that story is call quality. chalvh pairs four microphones with ENC (environmental noise cancellation), which the sheet says detects and removes about 80% of ambient noise. ENC is about the mic feed, not what you hear — so this is a "the person on the other end hears you clearly" feature, not a listening feature. Worth separating those two in your head before you buy.
Charging and controls are where chalvh plays it straight: USB-C, a full charge in about 1.5 hours, up to 8 hours per charge, and up to 50 hours total with the case. The case has an integrated LED digital display showing remaining case charge and bud charging status — a genuinely useful detail that saves you from guessing. Controls are touch-based (tap to play/pause, change volume, skip tracks, take calls, or trigger a voice assistant), and the buds connect to iOS 9.0 and Android 5.0 or newer. Bluetooth 5.4 is claimed to push transmission to 48 Mbit/s, cut latency to 100 ms, extend range to 15 m, and reduce power draw by 30% versus older versions.
Who should buy it: runners, gym-goers, and anyone who wants noise cancelling in a very light, hook-stabilized bud with a clear battery readout.
Who should skip it: if you want the absolute longest runtime between charges, or you simply prefer physical buttons over touch, the Faxoimu is the better fit.
The Faxoimu Earbuds sell one thing above all else: time. The case holds a 950 mAh battery and extends playback to a claimed 120 hours, with each bud running 8–10 hours on its own (85 mAh per bud). That is a huge gap over the chalvh's 50-hour total, and for some buyers it's the whole decision. If you're the person who forgets to charge, travels for a week, or just hates plugging in, this is the number that matters.
Faxoimu also leads on Bluetooth version: 6.1 versus 5.4 on the chalvh. Newer Bluetooth generations generally bring efficiency and connection-stability improvements, and Faxoimu explicitly frames it as a stable, uninterrupted-connection pitch with automatic reconnection to your last device. Note the range difference, though — Faxoimu lists 10 m, while the chalvh claims 15 m. If you like to leave your phone on a bench and walk around a gym floor, that's a real-world difference.
Sound is a 14.2 mm Hi-Fi dynamic driver, slightly larger than the chalvh's 14 mm, with Faxoimu emphasizing deep bass and clear highs. A marginally larger driver doesn't automatically mean better sound — tuning, seal, and codec support matter more — but if you like bass-forward music, the design brief here points that way.
Two honest trade-offs. First, the sheet lists button controls, not touch. That's actually a plus for many people: physical buttons work with gloves, in rain, and never misfire when you adjust the bud. But it's a different feel, and pressing a button can nudge the bud in your ear. Second, and more importantly, there's no active noise cancellation listed — you get passive isolation from the behind-the-ear fit, not electronics. And Faxoimu's own note says call use drops to about 3–4 hours, so if you take a lot of meetings or calls, plan on docking them more often than the music numbers suggest.
The rest is practical: IPX7 waterproofing (similar protection tier to the chalvh's IP7), a dual LED display showing real-time battery status, USB-C charging with about 2 hours to charge the case, and compatibility with phones, tablets, and laptops. Fit is behind-the-ear with a secure, pressure-free design aimed at running, yoga, gym work, and rainy conditions.
Who should buy it: long-haul travelers, commuters, and anyone who values runtime, the latest Bluetooth, and physical buttons over noise cancelling.
Who should skip it: if you fly often or work in loud spaces and want active noise cancelling, or if you make long calls all day.
• Best for battery life → Faxoimu Earbuds. Up to 120 hours total versus 50 hours on the chalvh, with a 950 mAh case against a smaller one.
• Best for noise cancelling → chalvh Ear buds. It's the only one of the two that lists Active Noise Cancellation; the Faxoimu relies on passive isolation.
• Best for the newest Bluetooth → Faxoimu Earbuds. Bluetooth 6.1 beats 5.4 on paper, even though the chalvh claims the longer 15 m range.
• Best for running and sweaty workouts → chalvh Ear buds. At 3 g per bud with soft ear hooks and IP7, it's clearly aimed at intense exercise.
• Best for call-heavy days → chalvh Ear buds. Four mics with ENC and up to 8 hours per charge, versus Faxoimu's stated 3–4 hours on calls.
• Best for physical controls → Faxoimu Earbuds. Buttons beat touch if you wear gloves or want zero accidental taps.
• Best for checking battery at a glance → a tie. Both use digital LED displays; chalvh shows case and bud status, Faxoimu shows dual real-time status.
• Best for bass-forward listening → Faxoimu Earbuds. A 14.2 mm driver tuned for deep bass, versus the chalvh's 14 mm titanium diaphragm with a flatter HiFi brief.
I'd buy the chalvh Ear buds for most people. The reason is simple: active noise cancellation, a 3 g hook-stabilized fit, and 8 hours per charge with ENC call clarity cover the widest range of daily use — commuting, working out, and taking calls. The 50-hour total is plenty for a week of normal use. I'd only switch to the Faxoimu if runtime is your single priority or you specifically want Bluetooth 6.1 and button controls. Check the current price on Amazon before deciding, since both sit in the budget-wireless tier and the gap between them may change your math.
That's the claimed total with the charging case, based on 8–10 hours per bud and a 950 mAh case. Faxoimu itself notes calls drop to about 3–4 hours, so treat 120 hours as music playback, not talk time.
Yes — the spec sheet lists Active Noise Cancellation for listening, plus four microphones with ENC for cutting background noise on calls. The Faxoimu sheet lists no active noise cancellation.
Both are built for sport. In my opinion the chalvh edges it for intense exercise thanks to 3 g per bud, soft ear hooks, and IP7 waterproofing, while the Faxoimu's behind-the-ear fit and IPX7 also hold up well.
Go with the Faxoimu. It uses physical push buttons for play/pause, track skipping, volume, and calls, so you never have to guess whether a tap registered.
