If you want true wireless earbuds that seal out noise and stay put through commutes, workouts and long focus sessions, choose JVC Gumy; if you need true wireless earbuds that clip onto your ear and let the world in while you run, cycle or wear glasses, choose crowm Third-generation Open Headphones.
• JVC Gumy biggest strength: Active Noise Cancelling plus an in-ear seal from four ear tip sizes — real isolation for noisy places.
• JVC Gumy biggest trade-off: The in-ear design plugs your ear canal, which some people find less comfortable over many hours, and it blocks the ambient sound you may want outdoors.
• crowm Third-generation Open Headphones biggest strength: A 4.1g clip-on, open-ear build that plays nicely with glasses, earrings and long outdoor sessions.
• crowm Third-generation Open Headphones biggest trade-off: No noise cancelling at all — by design you hear everything around you.
• Pick JVC Gumy if you want quiet, low-latency audio for gaming, streaming and focused work.
• Pick crowm if you want to stay aware of traffic and conversation while running, cycling or working out.
JVC Gumy is built around one idea: shut the world out. Active Noise Cancelling handles coffee shop chatter, office hum and traffic, and an Ambient Sound Mode flips that around when you need to hear your name called or stay aware while walking. In my opinion that dual-mode setup is the single most useful feature here, because it covers both the "deep focus" and "quick errand" halves of a normal day.
The fit story is deliberately active. An ergonomic stem design follows the curve of your ear, four ear tip sizes (S/M/L/XL) let you dial in a real seal, and IPX4 splashproofing covers sweat and light rain. Battery is 6 hours per charge with 20 more in the USB-C case, for 26 hours total. Bluetooth 5.4 keeps the connection stable, and a low-latency gaming mode cuts audio delay for competitive play and video. Touch controls handle playback and calls, and the translucent case comes in Olive Black, Coconut White, Mocha Brown and Grape Yogurt, with a strap holder for a bag or keychain.
Who should buy it: commuters, students, home-office workers and gamers who want noise gone and audio timed correctly. Who should skip it: anyone who wants to hear traffic clearly while running, or who simply can't tolerate an in-ear seal for hours — the open-ear idea below is the opposite philosophy.
crowm takes the other road entirely. These are Gen 3 clip-on, open-ear true wireless buds at just 4.1g each, with a C-shaped soft silicone bridge that flexes so it won't irritate your ear. The spec sheet specifically calls out small ears, glasses and earrings — that's the practical pitch. If normal earbuds press on your frames or fall out, a clip-on shape sidesteps the problem.
Audio runs through 13mm dynamic drivers with deep bass and crisp vocals, and sound leakage is kept minimal — important when open-ear design normally broadcasts your playlist to the room. Bluetooth 6.0 auto-pairs the moment you lift the buds out of the case, and the 10-meter range means you can leave your phone on a bench or in a bag mid-session. There's also a 60ms low-latency dual mode for gaming and video.
Battery is 6 hours standalone and 30 hours total with the case, which is the longest figure in this comparison. Noise control is listed as "None" — that's not a flaw, it's the point. Touches control play/pause, track skipping and calls, and yes, the product information really does list AI translation with real-time capabilities, with the exact touch gestures spelled out in the manual. Who should buy it: runners, cyclists, glasses wearers and anyone who wants ambient awareness plus a secure clip. Who should skip it: anyone who needs to silence a noisy office or a plane cabin.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → JVC Gumy. It's the only one of the two with Active Noise Cancelling and an Ambient Sound Mode.
• Best for staying aware outdoors → crowm. Open-ear design preserves ambient sound, which matters on roads and trails.
• Best for total battery life → crowm. 30 hours total versus 26 hours on the JVC.
• Best for long single sessions → a tie. Both give 6 hours per charge; the difference is all in the case.
• Best for low-latency gaming and video → JVC Gumy. Its gaming mode targets delay, and crowm's 60ms figure is the one to weigh against it.
• Best for working out with sweat → JVC Gumy. It carries an IPX4 splashproof rating; crowm's sheet lists no water-resistance rating.
• Best for fit customization → JVC Gumy. Four ear tip sizes versus one fixed clip-on shape.
• Best for lighter wear → crowm. 4.1g per bud is about as light as a true wireless bud gets.
• On price: neither sheet lists a figure, so check the current price on Amazon before you commit.
I'd buy the JVC Gumy. In my opinion, noise cancelling plus a customizable in-ear seal is the more useful combination for the way most people actually listen — commuting, working, gaming and watching. The 26-hour total and IPX4 rating cover a normal week without fuss. I'd only switch to crowm if my priority were running or cycling outdoors, wearing glasses, or never wanting my ears plugged. If that's you, the 4.1g clip-on build and 30-hour total make it the smarter pick. Either way, confirm the current price on Amazon first.
Open the charging case and take the buds out. The crowm sheet says they auto-pair instantly once removed, with no manual steps. For the JVC Gumy, enable Bluetooth on your phone and select the earbuds from the device list; both use Bluetooth (5.4 and 6.0 respectively).
how to connect true wireless earbuds
Charge both the buds and the case first — about 2 hours for the JVC and 1.5 hours for crowm. Then turn on Bluetooth on your phone and pick the earbuds from the available devices. After the first pairing, both reconnect automatically when you take them out.
how to use true wireless earbuds
Both use touch controls on the bud itself. Taps handle play/pause, track skipping and answering or ending calls. crowm's sheet notes the exact gestures are listed in the product manual, so read that page before you start tapping.
how to bluetooth true wireless earbuds
Keep your phone within range: roughly 10 meters for the JVC Gumy and about 33 feet for crowm. Bluetooth 5.4 on the JVC and Bluetooth 6.0 on the crowm both aim for a stable link with less interference, so leave your phone on a desk or in a bag and the audio should hold.
