These two products sit in the same shopping cart surprisingly often, and it's easy to see why. One is a complete true wireless system built for gaming. The other is a three-pack of memory foam ear tips built to fix the fit of a Sony pair you already have. That's the whole comparison in one line, and it's worth saying out loud before we go any further: you are not really choosing between two earbuds. You're choosing between buying new hardware and upgrading the hardware you own.
• Logitech FITS True — biggest strength: A complete wireless earbud system with LIGHTSPEED low-latency wireless plus Bluetooth 5.2, 10mm dynamic drivers, dual beamforming mics, and up to 22 hours of total listening time with the case.
• Logitech FITS True — biggest trade-off: It's the whole package, so you're buying earbuds, case, cable and pouch as one unit — and it only makes sense if you actually need a new pair.
• COMPLY TrueGrip MAX Memory — biggest strength: Slow-recovery memory foam with SmartSkin Technology that molds to your ear canal for a stable, isolating seal, sold as three pairs in small, medium and large.
• COMPLY TrueGrip MAX Memory — biggest trade-off: It's an accessory, not a device. It only works with compatible Sony true wireless models, and it does nothing for you if you don't own one.
• Buy Logitech FITS True if you want one self-contained set of earbuds for PC, Mac, PlayStation, Switch and mobile, and you like the idea of tips that mold to your ears in about a minute.
• Buy COMPLY TrueGrip MAX Memory if you already own Sony WF-1000XM-series buds (or another listed model) and your problem is fit, slipping, or outside noise leaking in — not sound quality.
The G FITS is a gaming-first product, and the spec sheet reads that way. The headline is LIGHTSPEED wireless, Logitech's low-latency connection, paired with Bluetooth 5.2 so the same earbuds can jump between a console, a PC and a phone. On paper that's the pitch: one set of buds that follows you across platforms instead of forcing you to keep a gaming pair and a commuting pair.
Then there's LIGHTFORM, the fit system. The ear tips mold to your ears in about 60 seconds, and the point isn't just comfort — it's passive noise isolation. A tip that actually fills your ear canal blocks more outside sound than a generic silicone tip that only partly seals. Logitech also pairs that with noise control modes and a sound-isolation approach rather than active cancellation, so the isolation is coming from the physical fit.
Who it fits: someone who games across PC, Mac, PlayStation, Switch or mobile and wants one wireless set that handles all of it, plus calls and music in between. The molded-fit idea is genuinely appealing if standard tips never quite seal for you.
Who should skip it: if you already own a pair of Sony earbuds you like and your only complaint is fit, buying a whole new system is the long way around. Also skip it if you want active noise cancellation as a headline feature — the isolation here is physical, not electronic.
COMPLY TrueGrip MAX Memory: Who It's For
This is a very different product, and it deserves to be judged on its own terms. Comply TrueGrip MAX is a pack of memory foam replacement ear tips — three pairs, in small, medium and large, in black. The material is the whole story: soft, slow-recovery foam that you compress before insertion, then let expand inside your ear canal. That expansion is what creates the seal, and the seal is what creates the isolation.
The "MAX" version matters here. Comply's own framing is that TrueGrip MAX adds patented SmartSkin Technology on top of the standard TrueGrip formula, which brings better durability, moisture resistance and easier cleaning. If you've used plain foam tips before and found they degraded fast or got grimy, that's the upgrade you're paying attention to.
Compatibility is the gate. These tips are built for Sony true wireless models — WF-1000XM6, WF-1000XM5, WF-1000XM4, WF-1000XM3, WF-XB700, plus INZONE Buds, WF-C700N, WF-C510, LinkBuds S, WF-1000X, WF-C500, WF-SP800N and WF-SP700N. They're designed to still fit inside the charging case, which is the detail that trips people up with third-party tips. Installation is simple: line the open end up with the soundport, push firmly until it's fully seated and sitting straight.
Care is worth knowing before you buy. Warm water and a soft cloth only — alcohol-based cleaners and lotions will degrade the foam. A separate cleaning kit exists if you want easier maintenance. And the warranty is a manufacturing-specification warranty rather than a performance guarantee, which is normal for a consumable like this.
Who it fits: anyone with one of those Sony models whose earbuds slip, feel loose, or let too much outside noise in. Foam is the classic fix, and a proper seal usually improves perceived bass and overall focus at the same time.
Who should skip it: anyone without a compatible Sony model. These are not universal tips, and they won't go on a Logitech G FITS or most other brands. Also skip if you prefer the feel of silicone and don't want to deal with compressing and re-seating foam.
• Best for gaming latency → Logitech FITS True. LIGHTSPEED wireless is the entire reason this product exists.
• Best for platform coverage → Logitech FITS True. PC, Mac, PlayStation, Switch and mobile, via LIGHTSPEED and Bluetooth 5.2.
• Best for fixing earbuds you already own → COMPLY TrueGrip MAX Memory. It's a fit upgrade, not a replacement device.
• Best for noise isolation without electronics → COMPLY TrueGrip MAX Memory. Adaptive foam creates a physical seal; the G FITS relies on molded tips plus sound-isolation control modes.
• Best for voice clarity on calls and chat → Logitech FITS True. Dual beamforming mics are doing work the foam tips simply can't.
• Best for total listening time → Logitech FITS True. Up to 22 hours with the charging case, against zero battery in a pack of ear tips.
• Best for size flexibility → COMPLY TrueGrip MAX Memory. Three pairs across S/M/L, so you can find your seal and keep spares.
• Best for low-commitment upgrade → COMPLY TrueGrip MAX Memory. If your Sony buds are fine and only the fit is off, this is the smaller change.
If I had to pick one, I'd take the Logitech FITS True — but only because it's the complete product. It gives you the earbuds, the case, the low-latency wireless, the mics, the molded fit and the 22-hour battery in one purchase, and it works across the platforms most people actually play on. In my opinion it's the better buy for anyone starting from nothing.
That said, I wouldn't recommend it to someone who already owns Sony WF-1000XM-series buds and likes them. For that person, COMPLY TrueGrip MAX Memory is the smarter move: fix the seal, keep the buds you know, and skip the bigger spend. Two different problems, two different answers.
If your complaint is a loose fit or outside noise bleeding in, yes — slow-recovery foam expands to fill the ear canal in a way silicone can't. The MAX version adds SmartSkin Technology for durability, moisture resistance and easier cleaning, which is the main reason to pick it over Comply's standard TrueGrip foam.
No. These tips are specifically listed for Sony true wireless models like the WF-1000XM6, WF-1000XM5, WF-1000XM4, LinkBuds S and WF-C500. They aren't a universal fit, so check your model against the compatibility list before ordering.
Not in the electronic sense. Logitech describes the noise control as sound isolation, meaning the molded LIGHTFORM tips create a physical seal that blocks outside noise. That's why the 60-second molding step matters so much — a good seal is the whole mechanism.
The Logitech FITS True. LIGHTSPEED wireless, dual beamforming mics and multi-platform support are all gaming-focused features that a pack of ear tips can't replicate. The COMPLY tips only make sense as a companion if you're gaming on compatible Sony buds and the fit is your weak point.
