If you want a complete set of true wireless earbuds with active noise cancelling, a charging case and everything you need in one box, choose JVC Gumy; if you need replacement memory foam ear tips that upgrade the fit and noise isolation of Sony true wireless earbuds you already own, choose COMPLY TrueGrip MAX Memory.
• JVC Gumy — biggest trade-off: The stock silicone-style ear tips come in four sizes, but fit and noise isolation depend entirely on getting that seal right, and there's no memory foam option included.
• COMPLY TrueGrip MAX Memory — biggest strength: Slow-recovery memory foam that molds to your ear canal for a secure seal, with patented SmartSkin Technology for durability, moisture resistance and easier cleaning.
• COMPLY TrueGrip MAX Memory — biggest trade-off: These are ear tips only. No earbuds, no case, no cable, and they're built specifically for select Sony true wireless models.
• Choose JVC Gumy if you need earbuds, not accessories — for commutes, workouts and study sessions.
• Choose COMPLY TrueGrip MAX Memory if you already own compatible Sony earbuds and want a better seal, more comfort and stronger passive noise isolation from the tips you use every day.
The Gumy Premium is a self-contained true wireless setup. You get the earbuds, a USB-C charging case, a charging cable, four sets of ear tips (S/M/L/XL) and a user manual in the box. The earbuds use Bluetooth 5.4 with a stated 10-meter range, and the audio side runs a 6 mm dynamic driver with 16-ohm impedance and a 20 Hz–20,000 Hz frequency range. That's a conventional, well-understood spec sheet — nothing exotic, but nothing that leaves you guessing either.
Battery is where this model earns its place. JVC rates 6 hours per charge and 20 additional hours from the case, for 26 hours total, with a 2-hour charge time for both the buds and the case. There's also a low-latency gaming mode, which matters if you're watching YouTube or streaming movies and don't want audio trailing the picture. Active noise cancelling handles coffee shop chatter, office hum and traffic, and ambient sound mode flips you back to hearing your surroundings when you're walking or waiting for your name to be called.
Buy it if you want one purchase that covers listening, calls, workouts and travel. Skip it if you already own a pair of Sony true wireless earbuds you like and only want to fix their fit — in that case you'd be buying a second set of earbuds you don't need.
COMPLY TrueGrip MAX Memory: Who It's For
This is not a pair of earbuds. It's a three-pair pack of replacement ear tips (S/M/L) made from Comply memory foam, in TrueGrip Max Black. The mechanism is simple and it's the whole point: the slow-recovery foam compresses before you insert it, then gently expands inside your ear canal to form a seal. That seal is what improves noise isolation and helps keep the earbud from slipping — passively, without any electronics involved.
The MAX version specifically adds patented SmartSkin Technology, which Comply describes as enhancing durability, moisture resistance and ease of cleaning compared to the standard TrueGrip line. If you rotate through workouts, commutes and travel, that coating is the difference between tips that hold up and tips that degrade. Care matters here: warm water and a soft cloth only, and avoid alcohol-based cleaners or lotions, which break the foam down. There's also a Comply Cleaning Kit sold separately if you want to make maintenance easier.
The catch is compatibility, and it's a real one. These tips are built for Sony true wireless models — the WF-1000XM6, WF-1000XM5, WF-1000XM4, WF-1000XM3, WF-1000X, WF-XB700, WF-C700N, WF-C510, WF-C500, WF-SP800N, WF-SP700N, LinkBuds S and INZONE Buds. They're designed to fit inside the charging case, which is the detail people forget: a tip that's too tall can stop the case from closing. Installation is a firm push onto the soundport until the tip is fully seated and straight.
Buy it if you own one of those Sony models and the stock tips never quite sealed, or if you want more isolation without turning on ANC. Skip it if you don't own compatible Sony earbuds, or if you're shopping for earbuds in the first place — this pack contains no electronics at all.
• Best for battery life → JVC Gumy. 26 hours total (6 per charge plus 20 from the case) versus zero — the Comply tips have no battery of their own.
• Best for active noise cancelling → JVC Gumy. It has switchable ANC and ambient sound mode built in. Comply's isolation is purely passive, achieved through the foam seal.
• Best for noise isolation on earbuds you already own → COMPLY TrueGrip MAX Memory. If your Sony buds seal poorly, foam tips are often the cheapest fix.
• Best for workouts and rain → JVC Gumy. IPX4 splashproof protection covers sweat and light rain on the earbuds themselves.
• Best for long listening comfort → COMPLY TrueGrip MAX Memory. Slow-recovery foam molds to your ear rather than pressing on it, and SmartSkin adds moisture resistance for sweaty sessions.
• Best for gaming and video → JVC Gumy. Low-latency mode targets exactly that sync problem; ear tips can't address audio delay.
• Best for travel convenience → both, differently. Gumy's translucent case has a strap holder for a bag or keychain. Comply tips are small, light and designed to stay inside the charging case, so they travel with the earbuds.
• Best for a first-time buyer → JVC Gumy. It's a complete kit. Comply only makes sense as an upgrade to something you already have.
In my opinion, most people searching these two names should buy the JVC Gumy. It's the complete product: earbuds, case, cable, four tip sizes, ANC, ambient mode, low-latency gaming mode, IPX4 and 26 hours of total battery — a full true wireless setup with nothing else to buy.
I'd only recommend COMPLY TrueGrip MAX Memory if you already own a compatible Sony true wireless model and your problem is fit, slipping or weak isolation rather than missing hardware. In that specific case, foam tips are the smarter upgrade. For everyone else, the Gumy is the one that actually gets you listening.
FAQ
how to pair true wireless earbuds
how to connect true wireless earbuds
Once paired the first time, most true wireless earbuds reconnect on their own when you remove them from the case — Bluetooth remembers the device. If they don't, open your phone's Bluetooth menu and tap the earbud name to reconnect manually. Charging the case via USB-C first is worth doing before your first setup.
how to use true wireless earbuds
Insert them with a tip size that seals comfortably — the Gumy includes S/M/L/XL, while Comply provides S/M/L foam. Controls on the Gumy are touch-based, covering playback and switching between ANC and ambient sound mode. Comply tips aren't electronic, so all controls stay on your existing Sony earbuds.
are memory foam ear tips better than silicone tips
Not universally — it depends on what you want. Foam like Comply's TrueGrip MAX molds to the ear canal for a tighter seal, which improves passive noise isolation and helps stop earbuds slipping, and SmartSkin adds moisture resistance. Silicone tips, like the four sets included with the JVC Gumy, are easier to wipe clean and don't wear out the same way. If your earbuds already seal well, foam isn't necessary.
