• KZ AN01 biggest strength: It's a true wireless earhook adapter with Bluetooth 5.4, LDAC support, a 4-mic AI ANC system and a charging case that extends playtime to roughly 40 hours — but only if you already own compatible 0.75/0.78mm 2-pin earphones.
• KZ AN01 biggest trade-off: The earphones themselves are sold separately. It is an upgrade kit, not a finished headphone.
• Wentronic YG01 biggest strength: A self-contained over-ear headphone with 40mm dual-layer drivers, up to 58 hours of battery, ANC rated to cut ambient noise by up to 30 dB, 5 EQ modes and multipoint Bluetooth 5.3.
• Wentronic YG01 biggest trade-off: Bluetooth 5.3 with no LDAC listed, and it's a fixed over-ear design — you can't swap or upgrade the drivers.
• Who each pick is for: KZ AN01 for IEM owners who want wireless freedom without giving up their existing sound. Wentronic YG01 for anyone who wants one box, one charge, and a quiet commute.
The AN01 is a niche product, and it's honest about that. It's a pair of over-ear hooks that terminate in a 0.75/0.78mm 2-pin connector, so it physically plugs into detachable in-ear monitors. Once attached, the module handles the wireless side: Bluetooth 5.4 for the link, a headphone amplifier that supports LDAC and SBC, and touch controls on the housing. If you've already invested in a set of KZ sound-isolating IEMs, this is the piece that cuts the cable without asking you to buy new earphones.
Battery is the practical story. KZ rates the adapter at up to 8 hours per charge, with a 20-minute top-up giving about 2 hours of playback. The included case carries three additional charges, which is how the figure of up to 40 hours total is reached. For gym sessions, commutes and workdays that's plenty, and the USB-C cable in the box means you're not hunting for a proprietary charger.
Noise cancellation comes from a 4-microphone AI ANC system with dedicated processing hardware — an unusual amount of mic hardware for an adapter this size. The earhooks themselves are skin-friendly flexible TPU with an IPX4 rating, so sweat and light rain are tolerable, and the over-ear ergonomic shape holds the IEMs in place during high-energy activity.
Wentronic YG01: Who It's For
The YG01 is the opposite philosophy: one box, nothing to attach, nothing to charge separately. It's an over-ear headphone with oval earcups finished in faux leather and metal, a 40mm dual-layer dynamic driver, and a frequency range of 20Hz to 20,000Hz. Five built-in EQ modes cover rock, jazz, classical, electronic and pop, so you can shift the tuning without touching an app.
The headline number here is battery: up to 58 hours. That's the kind of figure that means you charge it on a Sunday and stop thinking about it for a week or two of commuting. Charging runs over USB-C, which the brand also describes as carrying lossless audio — useful if you'd rather wire in than stream.
Noise cancelling is active and rated to reduce ambient noise by up to 30 dB, toggled with a single button press. Calls run through a 3-microphone array that the brand says filters wind, crowd chatter and street noise. Multipoint connection lets it hold more than one device at once and hand audio over as calls come in, which is the feature that actually matters if you're bouncing between a laptop and a phone all day.
Comfort engineering is more thoughtful than the price tier usually suggests: the earcups rotate 8° to follow head shape, and both the cushions and headband use protein leather over thickened memory foam. Bluetooth 5.3 gives a 10-meter range, and there's a 3.5mm jack for wired listening when the battery is empty. The warranty description is listed as 6 months.
Who should buy it: travelers, office workers, students and anyone who wants a quiet space on demand without owning any other gear. Who should skip it: LDAC loyalists and people who want to keep using their own IEMs — the YG01 is a closed system.
• Best for LDAC and hi-res codec support → KZ AN01. LDAC is explicitly listed; the YG01's sheet lists Bluetooth 5.3 without naming LDAC.
• Best for battery life → Wentronic YG01. Up to 58 hours in one unit versus up to 8 hours per charge (up to 40 hours with the case) on the AN01.
• Best for people who already own IEMs → KZ AN01. It exists specifically to make 0.75/0.78mm 2-pin earphones wireless.
• Best for a complete, no-assembly purchase → Wentronic YG01. Drivers, cushions and controls all included; nothing sold separately.
• Best for travel and office noise → Wentronic YG01. Over-ear cups plus ANC rated to cut noise by up to 30 dB is the stronger isolation package for a plane or an open-plan floor.
• Best for workouts → KZ AN01. IPX4 sweat and water resistance and a secure over-ear hook fit suit high-energy activity; the YG01 sheet lists no water rating.
• Best for switching between laptop and phone → Wentronic YG01. Multipoint connection is built in.
• Best for wired fallback → Wentronic YG01. It has a 3.5mm jack; the AN01 charges over USB-C but has no analog input.
In my opinion, the YG01 is the better buy for most people, simply because it's a finished product. You open the box, pair it, and get up to 58 hours of ANC listening with multipoint and a wired backup — no prerequisites, no separate earphones to source. I'd pick the KZ AN01 only if you already own 2-pin detachable IEMs and specifically want LDAC without cables, because in that one scenario the AN01 does something the YG01 simply can't. Buy the YG01 if you want a headphone; buy the AN01 if you want to set your IEMs free. Check the current price on Amazon for both before you commit, since that's the one number that can flip this call.
what is ldac headphones
LDAC is a high-definition Bluetooth audio codec that transmits more data than standard SBC, which is why it's associated with higher-resolution wireless listening. "LDAC headphones" simply means a headphone or adapter that supports that codec. In this comparison, the KZ AN01 lists LDAC and SBC support; the Wentronic YG01's sheet lists Bluetooth 5.3 without naming LDAC.
what is ldac support in headphones
what is ldac codec in headphones
A codec is the method used to compress and send audio over Bluetooth. LDAC is one of the higher-bandwidth options, which is why the KZ AN01 pairs it with a dedicated headphone amplifier. If your priority is codec flexibility, the AN01 is the pick here; if your priority is battery and ANC, the YG01's up-to-58-hour runtime and up-to-30 dB noise reduction matter more.
is the KZ AN01 or Wentronic YG01 better for travel?
For travel I'd take the Wentronic YG01. Over-ear cups, ANC rated to reduce noise by up to 30 dB, up to 58 hours of battery, multipoint and a 3.5mm jack for in-flight wired use all point one way. The KZ AN01 is the better travel companion only if you already carry 2-pin IEMs and want the smallest possible kit.
