If you want true wireless freedom with active noise cancellation and a charging case that keeps you going for days, choose Sony WF-C700N; if you need a wired USB-C connection with a built-in mic and passive isolation for calls, classes and handheld gaming, choose AZLA ASE-600.
• Sony WF-C700N — biggest strength: Bluetooth 5.2 wireless freedom, active noise cancellation and a charging case rated for up to 35 hours of total playback.
• Sony WF-C700N — biggest trade-off: It's a wireless-only design, so there's no jack and no cable option when the battery runs down.
• AZLA ASE-600 — biggest strength: A wired USB-C connection with a Knowles balanced armature driver and a built-in mic — no pairing, no charging, no latency worries.
• AZLA ASE-600 — biggest trade-off: No active noise cancellation (only passive isolation from the eartips) and no battery or case at all, because it draws power from your device.
• Who each is for: Sony WF-C700N is for commuters, travelers and anyone who wants ANC and cable-free listening; AZLA ASE-600 is for students, call-heavy users and USB-C gamers who want a dependable wired set.
The WF-C700N is Sony's take on everyday true wireless earbuds. The headline feature is active noise cancellation, which is a different approach from simply plugging your ears — it actively works to reduce the drone of a bus engine, an air conditioner or a crowded room so your music and calls sit in front of the noise instead of fighting it. For anyone who listens in transit, that's the whole point of buying a set like this.
Around that core, Sony builds out the convenience package. Bluetooth 5.2 handles the wireless link, so you pair once and go. Touch controls on the earbuds manage playback, volume and calls without you reaching for your phone. The included charging case keeps them topped up on the move, and the rated battery life runs up to 35 hours of playback with the case factored in. A water-resistant build means rain and sweat aren't automatic dealbreakers, and multiple ear tip sizes let you dial in the seal and comfort.
AZLA ASE-600: Who It's For
The ASE-600 takes the opposite approach. It's a wired USB-C earbud, which sounds old-fashioned until you remember how many modern devices have dropped the headphone jack entirely. iPhone 15, 16 and 17, USB-C iPads, Android phones, laptops, tablets, the Nintendo Switch and the Steam Deck all support USB-C audio — and that's exactly the list AZLA targets. Plug in and you're listening. No pairing menus, no codec handshake, no charging case to remember.
The audio side leans on a Knowles balanced armature driver rather than a dynamic one. Balanced armature drivers are known for detail and clarity, and AZLA tunes this one for natural vocals and balanced detail — a sensible choice for podcasts, lectures, video calls and everyday music rather than bass-heavy listening. The built-in microphone handles voice pickup for online classes, meetings, gaming chat and phone calls, which is the other half of why this set exists.
Noise handling is where you need to set expectations. The ASE-600 does not have active noise cancellation. What it does have is passive isolation: the included eartips seal your ear canal, which naturally cuts down surrounding distractions. In a quiet library or a home office, that's plenty. On a loud train, it won't compete with an ANC set.
Who should buy it: students in online classes, remote workers on calls all day, and USB-C gamers who want low-latency audio and a mic without a dongle. Who should skip it: anyone who wants wireless freedom or active noise cancellation, and anyone whose primary device still uses a Lightning port or a 3.5 mm jack. The orange silicone build is also a very different look from Sony's black plastic-and-case package — that's a taste call, not a performance one.
Side-by-Side: Which Should You Choose?
• Best for active noise cancellation → Sony WF-C700N. ANC is the entire premise of the C700N; the ASE-600 relies on passive sealing only.
• Best for battery life and travel → Sony WF-C700N. Up to 35 hours of playback with the charging case, plus a water-resistant build.
• Best for calls, classes and meetings → AZLA ASE-600. The built-in mic is purpose-built for voice pickup, and there's no pairing or charging to interrupt a call.
• Best for USB-C devices and gaming → AZLA ASE-600. Switch, Steam Deck, USB-C iPads, laptops and iPhone 15/16/17 all work over the wired connection.
• Best for detail-focused listening → AZLA ASE-600. The Knowles balanced armature driver is tuned for natural vocals and balanced detail.
• Best for gym and rainy commutes → Sony WF-C700N. The water-resistant design and secure in-ear fit handle sweat and weather.
• Best for zero-maintenance simplicity → AZLA ASE-600. No battery, no case, no charging routine — it powers off your device.
In my opinion, the Sony WF-C700N is the more versatile buy for most people. Active noise cancellation, Bluetooth 5.2, touch controls, water resistance and a charging case that stretches playback to 35 hours cover more situations — commute, gym, travel, calls — than any single wired design can. I'd only steer you to the AZLA ASE-600 if your devices are USB-C first and your day revolves around calls, classes or handheld gaming, where the wired connection, Knowles driver and built-in mic win outright. Decide by your devices and your noise problem, not by the spec sheet alone.
Not universally — they solve different problems. The WF-C700N wins on wireless freedom, active noise cancellation and battery life; the ASE-600 wins on wired USB-C reliability, the Knowles driver and its built-in mic for calls and classes.
No. It has passive noise isolation from its eartips, which reduces surrounding distractions by sealing the ear canal. If you want active noise cancellation, the Sony WF-C700N is the one with ANC.
Yes, on USB-C iPhones — AZLA lists iPhone 15, 16 and 17 compatibility. Older Lightning-port iPhones aren't covered. It also works with USB-C iPads, Android phones, laptops, the Switch and the Steam Deck.
The AZLA ASE-600, in my opinion. Its built-in microphone is specifically tuned for clear voice pickup in meetings, classes and gaming chat, and the wired connection means no pairing or battery interruptions mid-session.
Ask two questions: does your device still have a usable USB-C audio port, and do you need to block out loud background noise? USB-C plus a quiet-to-moderate environment points to the ASE-600. Bluetooth plus real ambient noise points to the WF-C700N.
