If you want a headphone built around deep, physical bass and long-haul battery life, choose Skullcandy Crusher ANC 2; if you need a lightweight, call-first headset with a boom-free mic system and certified Microsoft Teams support, choose Lenovo ThinkPad Dual Mode. Two very different products, two very different jobs.
• Skullcandy Crusher ANC 2 — biggest strength: Patented multi-sensory Crusher Bass with twin 40mm full-range drivers plus dedicated dual bass drivers, backed by up to 60 hours of battery with ANC off.
• Skullcandy Crusher ANC 2 — biggest trade-off: It's a heavy over-ear at 557.91 g, and it's clearly tuned for entertainment rather than enterprise call platforms.
• Lenovo ThinkPad Dual Mode — biggest strength: Sound by Bose with adaptive hybrid ANC and AI-powered environmental noise cancellation on the mic, plus official Microsoft Teams certification.
• Lenovo ThinkPad Dual Mode — biggest trade-off: On-ear fit with 28mm drivers and Environmental Noise Cancellation rather than the adjustable 4-mic ANC setup of the Crusher.
• Who Skullcandy Crusher ANC 2 is for: listeners who want to feel their music, movies and games, and who want to go days between charges.
• Who Lenovo ThinkPad Dual Mode is for: hybrid and office workers who live on calls and want a foldable, ~153 g headset they can wear all day.
The Crusher ANC 2 is a headphones-first product, and the spec sheet says so. Skullcandy pairs two full-range 40mm dynamic drivers with additional dual bass drivers and calls the result multi-sensory Crusher Bass — the point being that low frequencies aren't just audible, they're felt. If you've ever wanted a soundtrack with a physical thump behind it, that's the design intent here. The impedance sits at 32 ohm with a 20 Hz–20 kHz frequency range, which is a mainstream, easy-to-drive profile rather than an audiophile curve.
The noise cancellation is adjustable and runs on four microphones, and Skullcandy gives you two ways to shape the sound: a custom 5-band EQ in the Skullcandy App, plus on-headphone preset modes for music, movie and podcast. There's also Personal Sound by Mimi, a Stay-Aware mode so you can hear your surroundings, and multipoint pairing so you can jump between two devices at once. Bluetooth 5.2 with a 10 metre range covers normal room-to-room use, and a 3.5mm jack means you can go wired when you want to. Battery is the headline: up to 60 hours with ANC off, and Rapid Charge gives you 4 hours of listening from a 10-minute top-up. The listed average battery life is 50 hours, and the charge time is listed at 50 hours. Controls are button and touch, with app and voice control as options. In the box you get the headphones, a cable, a protective case, a USB-C charging cable and guides, backed by a 1-year manufacturer warranty.
Who should buy it? People who treat audio as entertainment — gym sessions, travel, studying, gaming, movie nights — and who want the bass to be the main event. The over-ear faux leather and silicone build in the Hazard colourway is a lifestyle look, not a boardroom one. Who should skip it? Anyone who needs a headset optimised for Microsoft Teams or similar UC platforms, and anyone sensitive to weight, because 557.91 g is substantial on the head over a long day. If you mostly take calls in an open office, this isn't the tool for that job.
The ThinkPad Dual Mode 8550 (Aura Edition) is the opposite kind of product: a work headset that also happens to sound good. Lenovo licenses Sound by Bose here, tuned for both calls and music with an emphasis on consistent voice quality and natural balance. The driver is a 28mm dynamic unit, impedance is 16 ohm, sensitivity is 120 dB and frequency response reaches 20 kHz — low impedance and high sensitivity, which is exactly what you want from something meant to run off a laptop, a phone or a USB receiver without fuss.
That last point matters. "Dual Mode" refers to the two ways it connects: Bluetooth 5.3 for wireless freedom, or a USB-A / USB-C receiver for stable, low-latency performance. You also get dual Bluetooth connections and storage for up to 8 paired devices, so switching between a laptop and a phone is quick. The design is on-ear with oval earcups in Thunder Grey, and it weighs roughly 153 g — a fraction of the Crusher's mass. It folds, the earcups are replaceable, and Lenovo backs it with a 3-year manufacturer warranty. In the box: the headset, a cable, a protective case, a user manual and a wireless transmitter.
On the noise front, Lenovo uses Adaptive Hybrid Active Noise Cancellation to cut distractions, paired with AI-powered Environmental Noise Cancellation that focuses on your voice during calls — which is the part colleagues actually notice. It's certified for Microsoft Teams and optimised for leading UC platforms, with push-button and touch controls.
Who should buy it? Anyone whose calendar is full of meetings, especially in shared or open-plan spaces, and anyone who wants one headset for both work calls and music. Who should skip it? If your priority is chest-thumping bass and marathon battery for entertainment, the smaller 28mm drivers and on-ear fit here aren't aimed at that. And if you specifically want adjustable, multi-level ANC tuning you can dial in yourself, the Crusher's 4-mic adjustable system gives you more control.
• Best for bass and immersive entertainment → Skullcandy Crusher ANC 2. Dual bass drivers plus a custom 5-band EQ for tuning the low end.
• Best for work calls and meetings → Lenovo ThinkPad Dual Mode. Microsoft Teams certified with AI-powered Environmental Noise Cancellation on the mic.
• Best for battery life → Skullcandy Crusher ANC 2. Up to 60 hours with ANC off, plus Rapid Charge giving 4 hours from 10 minutes.
• Best for all-day comfort and portability → Lenovo ThinkPad Dual Mode. About 153 g, foldable, with replaceable earcups.
• Best for low-latency, stable connection → Lenovo ThinkPad Dual Mode. Bluetooth 5.3 or the USB-A / USB-C receiver.
• Best for switching between two devices → a tie, but differently. Crusher ANC 2 has multipoint pairing; ThinkPad Dual Mode supports dual Bluetooth plus up to 8 saved devices.
• Best for adjustable noise cancellation → Skullcandy Crusher ANC 2. Four microphones with adjustable ANC and a Stay-Aware mode.
• Best for long-term ownership peace of mind → Lenovo ThinkPad Dual Mode. A 3-year manufacturer warranty versus 1 year on the Crusher.
In my opinion, the Lenovo ThinkPad Dual Mode is the smarter buy for most people who need one headset to do everything — it's light, foldable, certified for the platform your meetings actually run on, and flexible enough to work over Bluetooth or a USB receiver. That said, if your listening is about feeling the music rather than taking calls, I'd pick the Skullcandy Crusher ANC 2 without hesitation; nothing in the ThinkPad's spec sheet is trying to compete with dual bass drivers and 60-hour playback. Buy the ThinkPad for work. Buy the Crusher for everything after hours. Check the current price on Amazon before you commit, since both sit in very different budget brackets.
what is anc wireless headphones
ANC stands for Active Noise Cancellation. It means the headphones use microphones to pick up surrounding noise and emit signals that cancel it out, so you hear less of the world around you. The Skullcandy Crusher ANC 2 uses four microphones for adjustable ANC, while the Lenovo ThinkPad Dual Mode uses Adaptive Hybrid ANC plus AI-powered Environmental Noise Cancellation for calls.
what does anc mean on bluetooth headphones
On Bluetooth headphones, ANC describes the same active noise-cancelling process — it's a feature of the headset itself, not the wireless connection. Both products here offer it: the Crusher ANC 2 pairs it with a Stay-Aware mode and app EQ, and the ThinkPad Dual Mode combines it with a call-focused mic system and a 3.5mm-free USB-C / Bluetooth dual connection.
what is anc on bluetooth headphones
It's the noise-cancelling circuitry built into the earcups. Effectively, the headphones listen to your environment and neutralise steady background noise so music and voices come through more clearly. The design difference to note is that the ThinkPad's ANC is tuned alongside its Teams-certified mic setup, while the Crusher's focus is on uninterrupted entertainment listening.
what is the best anc headphones
There's no single best — it depends on the job. In my opinion, the Skullcandy Crusher ANC 2 is the better pick for entertainment thanks to its multi-sensory bass, adjustable 4-mic ANC and up to 60 hours of battery, while the Lenovo ThinkPad Dual Mode is the better pick for work calls because of its Microsoft Teams certification, Sound by Bose tuning and roughly 153 g weight.
