If you want a lightweight, secure-fit sports headphone with the APT-X codec and a hook design that stays put, choose Motorola SF600; if you need hybrid active noise cancellation, long battery life and app-based tuning, choose TOZO Hybrid Active Noise.
• Motorola SF600 biggest strength: APT-X codec support with a hook-style in-ear fit, Kevlar-reinforced materials, hydrophobic mesh and five sizes of ear cushions — a design built around movement and sweat.
• Motorola SF600 biggest trade-off: No noise control at all, and it's a single wireless headphone rather than a charging-case earbud pair.
• TOZO Hybrid Active Noise biggest strength: Hybrid ANC rated to reduce ambient noise by up to -45dB, 68 hours of total playtime with the case, 6 mics for calls, IPX8 waterproofing and a 32-preset EQ app.
• TOZO Hybrid Active Noise biggest trade-off: It's a much more feature-dense product, which means more settings to learn and an app you'll want to install to get full value.
• Who the Motorola SF600 is for: Runners and gym-goers who want a simple, secure, APT-X-capable headphone and don't care about ANC.
• Who the TOZO Hybrid Active Noise is for: Commuters, remote workers and travelers who want to block out the world and customize their sound.
The SF600 is a sports headphone in the most literal sense. The spec sheet tells the story before you even get to the audio side: hydrophobic mesh, Kevlar in the enclosure material, silicone seals, and a hook-shaped earpiece that anchors around the ear instead of relying purely on an in-ear seal. Motorola ships ear cushions in five sizes, which is unusually generous and matters a lot when you're moving — a fit that's slightly off is a fit that fails at mile three.
On the audio side, the headline is APT-X codec support. That's the reason this page exists as an "aptx hd earbuds" comparison at all. APT-X is a Bluetooth codec aimed at getting wireless performance closer to wired, and Motorola's own positioning here is that the SF600 was designed and tested to match wired headset performance. It's a single dynamic driver, wireless over Bluetooth, with media controls on a remote. There's no companion app, no EQ menu, no firmware tinkering.
That simplicity is either the point or the problem, depending on who you are. If you want to put them on, hit play, and forget about them while you run, the SF600 is exactly the right kind of boring. If you want to silence a plane cabin or take a call in a noisy café, look elsewhere — the noise control field on this one reads "None," and there's no transparency mode, no case battery, no app.
So: buy it if you're a runner, cyclist or gym regular who wants a secure hook fit, sweat-tolerant materials, size options and APT-X audio without a smartphone app in the loop. Skip it if noise cancellation, long total battery life or call clarity in loud places are on your must-have list.
The TOZO NC3 is the opposite philosophy: throw every modern earbud feature at the wall and see what sticks. Hybrid active noise cancellation rated up to -45dB, aimed specifically at steady low-frequency rumble — subway, aircraft engines, air conditioning hum. That's the honest framing of what ANC does well, and TOZO states it plainly rather than promising silence in every environment.
Battery is the other headline. ANC off you get up to 13 hours per charge and 68 hours total with the case; ANC on it drops to about 9.5 hours per charge and 40 hours total. A 10-minute top-up gives roughly an hour of playback, which is the kind of detail that actually matters when you're walking out the door. SmartPow power management is doing some of the work behind those numbers.
Then there's the rest of the stack: 6 microphones with ENC for calls, Transparency Mode for hearing announcements without pulling an earbud out, Bluetooth 5.3 with auto-pairing on case open and a one-key reset, IPX8 waterproofing, a 12mm dynamic driver with OrigX 2.0 tuning and Bass Plus, and a companion app with 32 EQ presets plus white noise tracks and AI chat features. Six pairs of ear tips (XS through XXL) come in the box.
Who should buy it? Commuters, frequent flyers, remote workers taking calls in busy spaces, and anyone who wants to sculpt their own sound signature. Who should skip it? Someone who wants zero setup friction. Between the app, the EQ profiles, transparency switching and ANC modes, this is a product you configure. If that sounds like homework, the Motorola is the calmer choice.
• Best for noise cancellation → TOZO Hybrid Active Noise. Up to -45dB hybrid ANC versus no noise control on the Motorola.
• Best for total battery life → TOZO Hybrid Active Noise. Up to 68 hours with the case (ANC off), plus a 10-minute quick charge for about an hour of playback.
• Best for secure fit during hard workouts → Motorola SF600. Hook-shaped earpieces, Kevlar and silicone construction and five cushion sizes are designed around staying put.
• Best for call clarity in noisy places → TOZO Hybrid Active Noise. Six microphones with ENC versus no listed call-noise processing on the SF600.
• Best for APT-X codec support → Motorola SF600. It's the only one of the two with APT-X named in its audio specs.
• Best for customizing your sound → TOZO Hybrid Active Noise. 32 EQ presets in the app and a 12mm driver with Bass Plus give you far more control.
• Best for water exposure → TOZO Hybrid Active Noise on paper. IPX8 is a formal waterproof rating; the Motorola relies on hydrophobic mesh and moisture-resistant materials without a stated IP number.
• Best for simplicity → Motorola SF600. No app, no modes, no case to manage — just connect and go.
If I were buying for myself, I'd take the TOZO Hybrid Active Noise. In my opinion the feature gap is just too wide to ignore: active noise cancellation, 68 hours of case-backed playtime, six mics, IPX8, transparency mode and an EQ app cover commuting, travel, calls and workouts in one product. The Motorola SF600 still has a real place — if APT-X audio and a hook fit are your two priorities and you never want to open an app, it's the more focused tool. But as a single do-everything pair, I'd go TOZO. Check the current price on Amazon before you commit, since pricing moves around.

Of these two, only the Motorola SF600 lists APT-X codec technology in its audio specs. The TOZO NC3 lists Bluetooth 5.3 connectivity but does not name APT-X in its data. If APT-X support is a hard requirement, the Motorola is the one that states it.
It uses hybrid active noise cancellation rated to reduce ambient noise by up to -45dB, and it's specifically designed for steady low-frequency sounds like subway rumble, plane engines and AC hum. Multiple ear tip sizes help you get a proper seal, which is what makes the reduction consistent.
With ANC off you get up to 13 hours per charge and 68 hours total with the charging case. With ANC on, that drops to roughly 9.5 hours per charge and 40 hours total. A 10-minute quick charge gives you about an hour of playback.
The SF600 uses hydrophobic mesh, Kevlar and silicone seals to resist moisture and sweat, which suits workouts and light rain. It does not carry a stated IP waterproof rating like the IPX8 on the TOZO, so I wouldn't treat it as a fully submersible pair.
