How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, sweat-ready pair of over-ear headphones you can throw in a bag and take straight to the gym, choose Amazon Renewed TREBLAB Z2; if you need maximum battery life, an app-tunable sound profile, and longer-range Bluetooth for all-day listening at a desk or on a plane, choose Cleer Audio Enduro ANC.
• Amazon Renewed TREBLAB Z2 — biggest strength: IPX4 water resistance plus a foldable, cased design built for workouts and travel. Biggest trade-off: battery life tops out around 35 hours and it's a renewed unit, not new.
• Cleer Audio Enduro ANC — biggest strength: up to 60 hours of battery with ANC on, plus a companion app for EQ and ambient-mode tuning. Biggest trade-off: no IPX4 sweatproof rating, so it's less suited to heavy training.
• Battery life → Cleer Audio Enduro ANC, by a wide margin.
• Workout durability → Amazon Renewed TREBLAB Z2.
• App-based sound customization → Cleer Audio Enduro ANC.
• In my opinion, the Z2 is for the fitness-first buyer; the Enduro ANC is for the long-session listener.
The TREBLAB Z2 is a hybrid active-noise-cancelling over-ear headphone with a very specific personality: it's a fitness headphone first and a general-listening headphone second. The IPX4 rating means it shrugs off sweat and light rain, and the foldable build with a carry case makes it easy to toss in a gym bag without worrying about it. If your listening happens on a treadmill, on a run, or on the weight bench, the design intent here is obvious. It weighs 0.53 lb, which is on the heavier side for over-ears, but the swivel ear-cups and plush memory-foam pads are meant to spread that weight and avoid the ear-warming, pressure-heavy feel you get from cheaper on-ear designs.
Audio-wise, the Z2 runs 40mm dynamic drivers with a 20 Hz–20 kHz frequency range, 32-ohm impedance, and 103 dB sensitivity — the kind of numbers that pair easily with a phone and don't demand a headphone amp. Bluetooth 5.0 with the aptX codec and multipoint support means you can stay connected to two devices and switch between them, and the 65 ms gaming mode keeps audio and video reasonably in sync for casual gaming or video watching. There's also a 3.5 mm jack, so you can go wired when the battery runs down. Call quality is handled by cVc 6.0 noise cancellation, which helps on the mic side rather than the speaker side.
Cleer Audio Enduro ANC: Who It's For
The Cleer Audio Enduro ANC is the opposite kind of headphone: it's built for long, stationary listening sessions rather than sweat. The headline number is battery — up to 60 hours with active noise cancellation engaged, which is roughly double what the Z2 offers. A 10-minute quick charge returns about 3 hours of playback, so even a rushed top-up covers a full transatlantic flight or a long workday. For anyone who resents charging headphones every few days, this is the whole pitch.
The drivers are 40mm ironless dynamic units covering 20 Hz–20 kHz, tuned for what Cleer describes as a Hi-Res-leaning profile with bold, articulate bass. Bluetooth 5.0 with aptX Adaptive handles the wireless side, and the Bluetooth range is listed at 15 meters — noticeably longer than the Z2's 10 meters, which matters if you like to leave your phone on a desk and wander around a room. Multipoint pairing lets you hold two devices at once and switch between them, which is genuinely convenient if you juggle a laptop and a phone all day. The 3.5 mm jack gives you a wired fallback too.
Where the Enduro ANC pulls ahead for tinkerers is the Cleer+ app. You get preset and custom EQ curves, adjustable noise-cancelling and ambient-noise levels so you can let in some awareness when you need it, and firmware updates. Controls are touch-based with a volume control, which is a different interaction style from the Z2's physical buttons — some people love the tap-and-swipe approach, others miss real buttons. On the build side, it's a lightweight over-ear with soft cushioned ear cups and an adjustable headband aimed at extended comfort, and it ships with a carry case and cable. The clear trade-offs: there's no IPX4 rating, so it isn't the headphone for heavy sweat, and the warranty situation is a standard one-year term on a new unit. If you want a desk, commute, or travel headphone with exceptional battery and sound customization, this is the fit. If you need sweatproofing, look elsewhere.
Side-by-Side: Which Should You Choose?
• Best for battery life → Cleer Audio Enduro ANC (up to 60 hours with ANC on vs. 35 hours on the Z2).
• Best for sound customization → Cleer Audio Enduro ANC (Cleer+ app with EQ presets, custom EQ, and adjustable ANC/ambient levels).
• Best for quick top-ups before a session → TREBLAB Z2 (5 minutes of charge ≈ 2 hours of playback).
• Best for long charging gaps between sessions → Cleer Audio Enduro ANC (10 minutes ≈ 3 hours, and a much larger total capacity).
• Best Bluetooth range → Cleer Audio Enduro ANC (15 m vs. 10 m).
• Best for wired backup → tie — both include a 3.5 mm jack.
• Best for buyers who want a new unit and a longer warranty → Cleer Audio Enduro ANC (1-year warranty vs. the Z2's 90-day limited warranty).
In my opinion, the Cleer Audio Enduro ANC is the better all-round buy for most people. Doubling the battery life, adding an app for EQ and ambient control, and giving you longer Bluetooth range and a full year of warranty coverage are hard advantages to argue with. I'd pick the TREBLAB Z2 only if sweat resistance and a compact, cased, gym-ready design are your top priorities — that's a genuinely useful niche, but it's a niche. If you're on the fence, decide by your primary use case, then check the current price on Amazon before you commit.
It depends on how much you value sweat resistance and a lower upfront cost. You get IPX4 protection, a foldable cased design, and a 90-day limited warranty on a renewed unit. If a longer warranty and a new unit matter more, the Cleer is the safer pick.
The Cleer Audio Enduro ANC wins clearly: up to 60 hours with noise cancellation on versus about 35 hours on the Z2. Both offer quick-charge top-ups, but the Cleer's total capacity means far fewer charging sessions.
It's an over-ear headphone without an IPX4 rating, so it isn't designed for heavy sweat. For running, lifting, or anything that gets wet, the TREBLAB Z2's water resistance makes it the more sensible choice.
Yes. Both the TREBLAB Z2 and the Cleer Audio Enduro ANC include a 3.5 mm jack, so you can plug in directly if the battery is low or you want a latency-free wired connection.
