It is built around adjustable “sensory bass,” while JBL describes the Tune 770NC’s sound as JBL Pure Bass. Those descriptions show how each model is positioned; they are not the result of a controlled head-to-head listening test.
Which headphone is more bass-focused?
The Skullcandy Crusher ANC 2 is the more directly bass-focused choice. Skullcandy lists adjustable sensory bass and says listeners can adjust bass through its app. The JBL Tune 770NC is marketed with JBL Pure Bass sound, but its product description does not document the same adjustable sensory-bass feature. This supports a feature-based recommendation, not a claim that independent measurements prove the Skullcandy has objectively stronger bass.

How should you choose?
Choose Crusher ANC 2 for bass adjustment
Pick the Crusher ANC 2 if the ability to turn the bass effect up or down is central to your decision. Its documented sensory-bass controls make that priority explicit, and it also lists app-based EQ and personal sound customization.
Choose Tune 770NC for JBL Pure Bass and its battery claim
The Tune 770NC may suit you if you want JBL’s Pure Bass tuning and the specific manufacturer battery maximum of up to 70 hours with Bluetooth on and ANC off. That figure should not be treated as a runtime estimate with noise cancelling enabled.
