If you want long battery life for library sessions and a more adjustable listening setup, choose JBL Tune 720BT; if you need bass you can physically feel, choose Skullcandy Crusher Evo. For most library listeners, I’d choose JBL: its stated battery life is longer, and its sound can be adjusted through the JBL app. The Crusher Evo makes more sense when its distinctive, adjustable bass is the main draw.
• JBL Tune 720BT: Up to 76 hours of battery life, app-based EQ, and Voice Aware for calls; its standout trade-off is that it does not offer the Crusher Evo’s sensory bass effect.
• Skullcandy Crusher Evo: Adjustable bass with sensory feedback, a personal sound feature in the Skullcandy app, and up to 40 hours of battery life; it has less stated battery life than JBL.
• Both are wireless, over-ear headphones with folding designs and call controls.
• Choose JBL for longer listening stretches and sound customization; choose Skullcandy if bass you can feel matters more than maximum battery life.
The JBL Tune 720BT is the more straightforward pick for someone who wants to listen for long stretches without making battery management part of the routine. Its stated battery life is up to 76 hours. If you do need a top-up, a five-minute charge is specified to provide three more hours of music, while a full recharge can take as little as two hours using USB-C. That combination suits a student moving between classes, study blocks, and a commute.
Its Bluetooth 5.3 connection keeps the setup wireless, and the JBL Headphones app lets you adjust the sound with EQ. That gives you a way to tailor the listening profile rather than being locked into one presentation. The headphones also have ear-cup controls and Voice Aware, which lets you hear your voice during calls. For someone looking for a with microphone Bluetooth headset for library use and occasional calls, those call features are relevant—but they don’t establish how well the microphone performs in a noisy room.

The Tune 720BT is my pick if you want the best headband headphones for library listening based on the practical combination of long battery life, app EQ, and call handling. It folds flat for carrying and includes a detachable audio cable, so the design offers a wired option too. Skip it if your main goal is a dramatic, bass-heavy effect you can feel: the available specifications describe JBL Pure Bass sound, not the Crusher Evo’s sensory bass system.
The Skullcandy Crusher Evo has a more distinctive reason to choose it: its multi-sensory bass system adds an adjustable physical sensation to the low end. A wheel on the left ear cup controls the bass intensity. That makes it a more specialized option for listeners who want their music or movies to feel punchier, rather than simply wanting a general-purpose pair of wireless headphones.
It also offers a personal sound feature through the Skullcandy app. The listed process uses a hearing analysis to adjust sound levels for the individual listener. The headphones have button controls for calls, volume, and track changes, and their battery life is stated as up to 40 hours. Rapid Charge is specified to provide four hours of listening after a ten-minute charge. Those are useful provisions, though JBL’s stated maximum battery life is longer.
The Crusher Evo could suit a listener who wants that strong, adjustable bass character for music, movies, or travel. It folds and collapses for portability and comes with a protective case. For quiet study sessions, though, its defining bass feature may be unnecessary. If your priority is an uncomplicated library routine with the longest stated battery life between charges, the JBL is the more practical fit.
• Best for longer battery life → JBL Tune 720BT. Its stated maximum is up to 76 hours, compared with up to 40 hours for the Crusher Evo.
• Best for a five-minute top-up → JBL Tune 720BT. The listed quick charge adds three hours of music after five minutes.
• Best for a ten-minute top-up → Skullcandy Crusher Evo. Its Rapid Charge feature specifies four hours of listening from a ten-minute charge.
• Best for sensory bass → Skullcandy Crusher Evo. Its adjustable bass system is designed to add a physical sensation, which sets it apart from JBL’s stated Pure Bass sound.
• Best for app-based EQ adjustments → JBL Tune 720BT. The JBL app includes EQ controls for tailoring the sound.
• Best for a personal sound setup → Skullcandy Crusher Evo. Its app feature uses a hearing analysis to adjust sound levels.
• Best for occasional calls → Either, with different controls. JBL adds Voice Aware so you can hear your voice while talking; Skullcandy lists call controls for answering or rejecting calls. The provided information doesn’t establish which has the better microphone.
• Best for a library-first routine → JBL Tune 720BT. Its longer stated battery life and adjustable EQ are useful when you want headphones that can cover extended study sessions without the Crusher’s bass effect being the main attraction.
My Verdict
In my opinion, I’d buy the JBL Tune 720BT for a library-centered routine. Its up-to-76-hour battery life, EQ adjustments, and Voice Aware call feature make it the more versatile everyday choice on paper. I’d pick the Skullcandy Crusher Evo instead if adjustable, physically felt bass is the feature I value most. For the long sessions and occasional calls I’d want from headphones for library use, JBL is the better fit for me.
I’d choose the JBL Tune 720BT for most study routines because its stated battery life is longer and its app includes EQ adjustments. The Crusher Evo is more appealing if its sensory bass is a deliberate part of what you want from your listening.
The JBL Tune 720BT is listed for up to 76 hours of battery life; the Skullcandy Crusher Evo is listed for up to 40 hours. Actual listening time can vary, and the figures are product specifications rather than a guarantee for every use pattern.
Both list call-related controls. JBL also has Voice Aware, which lets you hear your voice during a call, while Skullcandy lists buttons for answering or rejecting calls. The available product details don’t provide a microphone-quality comparison.
First decide which features you’ll actually use: JBL’s longer stated battery life and EQ, or Skullcandy’s adjustable sensory bass and personal sound feature. To compare current prices, check the current price on Amazon; the better fit depends on which of those differences matters more to you.
