If you want the most refined noise cancellation, voice-assistant convenience and app-tunable control for long study sessions in a library, choose Bose QuietComfort 35; if you need longer battery life, a foldable travel-friendly build and a lower-cost way into active noise cancelling, choose Skullcandy Hesh ANC. Both are over-ear wireless noise cancelling headphones built for exactly the situation this article is about — quiet, focused listening in a library — and they get there in two very different ways.
• Bose QuietComfort 35 — biggest strength: three adjustable levels of active noise cancellation, a noise-rejecting dual-microphone system, Alexa voice control and the Bose Connect app for setup, Bluetooth management and firmware updates.
• Bose QuietComfort 35 — biggest trade-off: it charges over USB rather than USB-C, ships with a shorter 12-inch USB cable, and its Bluetooth 4.1 spec is a generation behind the Skullcandy's Bluetooth 5.
• Skullcandy Hesh ANC — biggest strength: up to 22 hours of battery with Rapid Charge (roughly 10 minutes of charging for about 3 hours of listening), 4-mic active noise cancelling, plus built-in Tile finding technology and an extra USB-C cable in the box.
• Skullcandy Hesh ANC — biggest trade-off: the noise cancelling is 4-mic ANC without the multi-level adjustability Bose offers, and the headphone jack is absent — it's wireless with USB-C charging only.
• Choose Bose QuietComfort 35 if you want granular control over how much of the library's ambient hum you let in and you value voice control.
• Choose Skullcandy Hesh ANC if you want the longest rated battery life and a flat-folding, collapsible design you can toss in a bag.
The QuietComfort 35 II is the more "engineered" of the two. Its headline feature is three levels of active noise cancellation, which matters more than it sounds. In a library, the noise floor isn't one thing — it's a ventilation hum, a keyboard clatter, a distant conversation. Being able to dial cancellation up or down through the Bose Connect app lets you stay aware without yanking the headphones off. Add the noise-rejecting dual-microphone system and you get clearer voice pick-up if you take a call at a study table.
Then there's Alexa. The Action button gives you voice access to music and information, so you can queue something up or check a fact without reaching for your phone — a small thing that adds up over a long study block. Bose also leans into connectivity: hassle-free Bluetooth pairing, personalized settings, and access to firmware updates through the app. The balanced audio tuning is described as performing consistently at any volume, which is exactly what you want when you're listening quietly so you don't disturb the room. Battery is rated at 20 hours, and the package includes the QC35 II headphones, a charging cable, a backup audio cable and a carry case.
Who should buy it: someone who wants fine control over noise cancellation, built-in voice assistance, and a complete kit with a carry case and backup cable. Who should skip it: someone who wants the longest possible battery life, USB-C charging, or a folding frame — the QuietComfort 35 doesn't fold flat and charges over USB.
The Hesh ANC plays a different game: durability, portability and stamina. The 4-mic active noise cancelling is the core feature — it's designed to let you disappear into music, movies or podcasts, which is the whole point of bringing headphones into a library. It won't give you Bose's stepped adjustability, but it will cut the room down to something you can ignore.
The battery story is where it pulls ahead on paper: up to 22 hours, with Rapid Charge giving you about 3 hours of playback from a 10-minute top-up. That's the kind of thing that saves a study session when you realize you forgot to charge the night before. The bundle includes an extra 1.6 ft USB-C to USB-C cable in addition to the standard charging cable, and charging is USB-C — a modern, reversible connector you likely already carry.
Physically, the Hesh ANC is built for life in a backpack: flat-folding and collapsible, with a plastic enclosure that keeps weight down. Button controls handle calls, volume and track skipping without app gymnastics. And built-in Tile finding technology means that when you register the product in the Tile app, you can locate the headphones if they slip under a chair or into the wrong bag — genuinely useful for a commuter or a student. Skullcandy backs it with a 1-year limited warranty.
Who should buy it: someone who wants long battery life, USB-C charging, a foldable design and a locate-it feature, and who is fine with simpler ANC controls. Who should skip it: someone who needs a wired fallback (there's no headphone jack) or wants adjustable cancellation levels.
• Best noise-cancellation control → Bose QuietComfort 35. Three adjustable levels beat a fixed ANC profile when you want to tune how much of the room you let in.
• Best long battery life bluetooth headset for library → Skullcandy Hesh ANC. Up to 22 hours versus 20 hours, plus Rapid Charge for emergencies.
• Best for voice assistance → Bose QuietComfort 35. Alexa voice control via the Action button is a feature the Hesh ANC simply doesn't have.
• Best for portability → Skullcandy Hesh ANC. Flat-folding and collapsible wins over a non-folding frame for bag life.
• Best charging convenience → Skullcandy Hesh ANC. USB-C, plus an extra cable included, versus USB charging on the Bose.
• Best for finding lost headphones → Skullcandy Hesh ANC. Built-in Tile finding technology is a real differentiator.
• Best for a complete out-of-box kit → Bose QuietComfort 35. Carry case, charging cable and backup audio cable are all included.
• Best for wired listening → Bose QuietComfort 35. The backup audio cable gives you a fallback the Hesh ANC lacks.
For a library-focused buyer, I'd lean toward the Bose QuietComfort 35. The three adjustable noise-cancellation levels, the dual-microphone call clarity and Alexa voice control make it the more capable tool for long, quiet, focused sessions — and the included carry case and backup audio cable round it out. The Skullcandy Hesh ANC is the stronger pick if battery life, USB-C charging and a folding design matter most to you, and it's a very reasonable way into active noise cancelling. In my opinion, the Bose wins on control and polish; the Skullcandy wins on stamina and portability. If you want sweatproof headphones for library use, note that neither sheet lists an IP water-resistance rating — these are indoor over-ears, not gym gear. Check the current price on Amazon for both before you commit.
