If you want lightweight in-ear buds with a secure, sweat-friendly fit for workouts and commutes, choose JBL Tune Flex; if you need over-ear headphones with huge Crusher bass, longer battery life and multipoint pairing, choose Skullcandy Crusher ANC 2. They're two very different ways to buy wireless noise cancelling headphones, and the right pick comes down to how you listen all day.
• JBL Tune Flex — biggest strength: Lightweight in-ear design (just 10 g for the buds) with Active Noise Cancelling plus Smart Ambient, 4 mics for calls, and IPX4 water resistance so sweat and rain aren't a problem.
• JBL Tune Flex — biggest trade-off: It's a true wireless earbud, so total playtime depends on the charging case, and the 12 mm drivers deliver bass in an in-ear format rather than a thumping over-ear feel.
• Skullcandy Crusher ANC 2 — biggest strength: Patented multi-sensory Crusher Bass with two 40 mm full-range drivers plus dedicated dual bass drivers, adjustable 4-mic ANC, and up to 60 hours of battery with ANC off.
• Skullcandy Crusher ANC 2 — biggest trade-off: It's an over-ear headphone weighing 580 g, so it's bulkier to carry and more of a sit-down, travel, or desk companion than something you'd wear to the gym.
• Pick JBL Tune Flex if you want pocketable buds you can wear while running, commuting, or taking calls on the move.
• Pick Skullcandy Crusher ANC 2 if you want immersive, feel-it-in-your-chest bass and the longest possible listening time between charges.
The Tune Flex is built around convenience and versatility. The stick-style earbuds use 12 mm dynamic drivers tuned for JBL Pure Bass Sound, and because they sit in your ear rather than over it, they stay light — the buds weigh about 10 g. Active Noise Cancelling with two microphones cuts down background noise, and Smart Ambient gives you two useful modes: Ambient Aware lets you hear your surroundings, and TalkThru lets you hold a quick conversation without pulling the buds out.
Battery is where the case earns its keep. You get up to 32 hours total (8 hours in the buds plus 24 in the case), or 6 hours plus 18 in the case with noise cancelling engaged. Speed Charge is genuinely handy: 10 minutes gives you 2 hours of playtime. Bluetooth 5.2 and a 10-meter range cover normal phone-to-pocket distances, and the JBL Headphones App lets you adjust the EQ, touch controls and noise settings.
In my opinion, the Tune Flex is the better choice for anyone who moves a lot. IPX4 water resistance and sweatproofing mean workouts and light rain aren't a concern, and the four microphones with VoiceAware make it a solid pick for people who take calls constantly. Skip it if you want the physical sensation of deep, chest-thumping bass or if you prefer an over-ear fit for long listening sessions — that's simply not what an in-ear bud is designed to deliver.
The Crusher ANC 2 is a very different animal. This is an over-ear headphone with Skullcandy's patented multi-sensory Crusher Bass technology: two full-range 40 mm drivers plus additional dual bass drivers that add a physical, sensory layer to low frequencies. If you've ever wanted headphones that let you actually feel the bass rather than just hear it, this is the feature that defines the product. You can fine-tune that bass level through a custom 5-band EQ in the Skullcandy App, or switch between preset music, movie and podcast modes right on the headphones.
Noise cancelling is handled by four dedicated external microphones, and it's adjustable, so you can dial in how much of the outside world you block out. There's also a Stay-Aware mode for when you want to hear what's going on around you. Battery life is the headline number: up to 60 hours with ANC off, and Rapid Charge gives you 4 hours of listening from just 10 minutes of charging. Multipoint pairing lets you stay connected to two devices at once, which is ideal if you're switching between a laptop and a phone all day.
The trade-offs are real. At 580 g it's a substantial over-ear headphone, so it's best suited to travel, studying, gaming, the gym in a stationary sense, or desk work rather than stuffing in a pocket. It does include a 3.5 mm jack, a protective case and a USB-C cable, so wired listening and storage are covered. I'd steer you here if bass you can feel, marathon battery life and over-ear comfort matter more to you than portability.
Side-by-Side: Which Should You Choose?
• Best for bass you can feel → Skullcandy Crusher ANC 2. Dual bass drivers and multi-sensory Crusher Bass are the whole point of this model.
• Best for battery life → Skullcandy Crusher ANC 2. Up to 60 hours with ANC off beats the Tune Flex's 32-hour total.
• Best for portability → JBL Tune Flex. A charging case that fits in a pocket versus a 580 g over-ear headphone.
• Best for calls → JBL Tune Flex. Four microphones plus VoiceAware give you control over how much of your own voice you hear.
• Best for switching between devices → Skullcandy Crusher ANC 2. Multipoint pairing connects to two devices at once.
• Best for blocking noise on a plane or in a café → Skullcandy Crusher ANC 2. Adjustable 4-mic ANC over an over-ear seal.
• Best for quick top-ups → both. The Tune Flex's Speed Charge gives 2 hours from 10 minutes; the Crusher ANC 2's Rapid Charge gives 4 hours from 10 minutes.
• Best for staying aware outdoors → JBL Tune Flex. Ambient Aware and TalkThru are built specifically for that.
If I had to pick one, I'd buy the JBL Tune Flex for everyday life — commuting, workouts, calls and walking around town — because the in-ear fit, IPX4 rating and Smart Ambient features match how most people actually use headphones. But if your priority is a big, physical bass experience with the longest battery life and you mostly listen at a desk or while travelling, I'd choose the Skullcandy Crusher ANC 2 instead. Neither is universally better; they solve different problems. Before deciding, check the current price on Amazon, since that often settles a close call.
what are wireless noise cancelling headphones
They're headphones that connect over Bluetooth and use microphones and electronics to reduce surrounding noise. Both the JBL Tune Flex (in-ear, 2 mics for ANC) and the Skullcandy Crusher ANC 2 (over-ear, 4-mic adjustable ANC) fit that definition, just in different form factors.
