• JVC True — biggest strength: an 11mm neodymium dynamic driver and a full 20 Hz–20,000 Hz frequency range, backed by Bluetooth 5.1 and a familiar, no-fuss touch/voice control setup.
• JVC True — biggest trade-off: it uses sound isolation rather than active noise cancellation, its control method is voice-first, and it's explicitly designed for adult ears only.
• StitchGreen M45 — biggest strength: a 120-hour battery figure, IPX7 waterproofing, Bluetooth 5.3 with fast auto-pairing, and a 2200mAh case that can act as an emergency phone charger.
• StitchGreen M45 — biggest trade-off: an 8mm driver with a much narrower stated frequency range, no noise control at all, and a bulkier sci-fi-styled case that isn't as pocket-friendly.
• JVC True is for you if: you want a discreet, dependable daily-listening earbud and you mainly care about balanced sound and simple operation.
• StitchGreen M45 is for you if: you want maximum runtime, tougher water resistance, and a case that does double duty as a power source.
The JVC True is the more traditional of the two designs, and that's the point. It's built around an 11mm dynamic driver using a neodymium magnet — a fairly large driver for a true-wireless earbud — and the spec sheet lists a full 20 Hz to 20,000 Hz frequency range. That range is the standard span of human hearing, which tells me JVC is aiming for an even, all-purpose tuning rather than a bass-heavy one. If you listen to a mix of podcasts, acoustic music, and pop, that kind of tuning tends to hold up well across genres.
Who should buy it: someone who wants a compact, understated black earbud for commuting, calls, and general listening, and who values a well-known audio brand name and a one-year parts-and-labor warranty. Who should skip it: anyone who needs serious water protection, active noise cancellation, or use by kids — the sheet notes this model is designed to fit adult ears, and the age range is listed as adult. If you're shopping for a child or you swim with earbuds in, look elsewhere.
StitchGreen M45: Who It's For
The StitchGreen M45 goes the other way entirely: it's a spec-sheet maximalist. The headline number is 120 hours of battery life, powered by a 2200mAh case battery, and — unusually for earbuds — that case can serve as an emergency charger for your phone. If you've ever watched your phone die at a festival, a long travel day, or a campsite with no outlet, that feature alone changes the calculus. It ships with three sizes of ear caps (S, M, L), a USB-C charging cable, and a hard-shell package, and it's covered by a 180-day warranty.
Durability is another clear win: the M45 is rated IPX7, which means it can withstand immersion in water, not just splashes. For heavy sweaters, runners in the rain, or anyone who regularly gets caught out, that's a meaningful step up. Connectivity is Bluetooth 5.3, newer than the JVC's 5.1, with fast auto-pairing when you lift the buds out of the case and low-latency performance that StitchGreen pitches at gamers. You also get free switching between stereo and mono mode, plus compatibility with iPhones, Android phones, TVs, and laptops.
The sound story is more modest: an 8mm biological diaphragm and a stated frequency range of 20 Hz to 100 Hz — a narrow band that the description pairs with "deep 18Hz-20kHz bass." There's no noise control listed, and the controls are touch-based for calls, volume, and track changes. The sci-fi styling, breathing lights, and metal-painted cabin are a love-it-or-leave-it proposition. Who should buy it: frequent travelers, gamers, and outdoor users who want runtime, water resistance, and a backup battery in one package. Who should skip it: listeners who prioritize balanced, full-range audio or a discreet look.
• Best for all-around sound balance → JVC True. The 11mm neodymium driver and 20 Hz–20,000 Hz range point to a fuller, more even presentation than the M45's 8mm driver and narrow stated range.
• Best for battery life → StitchGreen M45. 120 hours versus 22 hours isn't close.
• Best for water and sweat → StitchGreen M45. IPX7 (immersion) beats IPX4 (splashing).
• Best for charging your phone on the go → StitchGreen M45. The 2200mAh case doubles as an emergency power bank.
• Best for newer Bluetooth and low latency → StitchGreen M45. Bluetooth 5.3 with fast auto-pairing and a gaming-friendly low-latency claim.
• Best for discreet, everyday wear → JVC True. A plain black ABS design with rounded tips and voice-assistant support is easier to wear anywhere.
• Best for kids and shared family use → StitchGreen M45. Its age range covers men, women, and children; the JVC is explicitly adult-fit.
• Best for a known audio brand and a longer warranty → JVC True. JVC is a long-standing audio name, and the warranty runs a full year on parts and labor versus 180 days.
If I were buying for myself and my priority were sound quality and a clean, unobtrusive daily earbud, I'd pick the JVC True. The larger 11mm neodymium driver and the full 20 Hz–20,000 Hz range are the specs I'd actually feel every day, and the adult-fit, voice-assistant-friendly design suits commuting and desk work. That said, if my life involved long trips, heavy sweating, or constantly running my phone battery down, I'd switch to the StitchGreen M45 without hesitation — 120 hours, IPX7, and a case that charges your phone are hard to argue with. Match the pick to your habits, not to the spec sheet alone.
Yes, clearly. StitchGreen lists up to 120 hours of playback with a 2200mAh case, while JVC lists up to 22 hours total with its charging case. If runtime is your top concern, the M45 is the stronger choice.
The StitchGreen M45. Its IPX7 rating means it can handle immersion, while the JVC True's IPX4 rating only covers splashing water. Both are in-ear designs, but the M45's water protection is meaningfully tougher.
On paper, the JVC True. Its 11mm neodymium dynamic driver and full 20 Hz–20,000 Hz frequency range suggest broader, more balanced coverage, while the M45 lists an 8mm driver and a narrow 20–100 Hz range. Sound is subjective, but the JVC's specs read more complete.
