When you look at the sub-$100 headphone market, you usually have to pick two out of three: good sound, good battery, or good features. The JBL Tune 770NC claims to offer all three, boasting a massive 70-hour battery life and Adaptive Noise Cancellation.
But does it hold up in the real world? We analyzed months of long-term usage reports—from daily commuters to office workers—to see if these headphones are a steal or a skip.

Quick Verdict
The JBL Tune 770NC is an endurance beast with a battery that refuses to die and that signature punchy JBL bass.2 It is an incredible value for students and commuters. However, it is not perfect—the build quality feels budget-friendly, and the ANC struggles with the heavy vibrations of bus travel.3
Rating: ⭐⭐⭐⭐ (4/5)
Best For: Students, Bass Lovers, Office Workers, Long Commutes.
Skip If: You have a large head (clamping force issues) or need silence on bumpy bus rides.
The Good: Why Users Love It
1. Battery Life That Lasts Weeks
The standout feature of the Tune 770NC is undeniably its battery efficiency. JBL claims up to 70 hours with ANC off and 44 hours with ANC on.4 Real-world users confirm this is not just marketing hype.
- One user reported charging them only twice in a whole year of use.
- Another user charged them once and went several days without needing a top-up, calling the battery “insanely good”.
2. Signature “Pure Bass” Sound
If you like Rock, Pop, or Hip-Hop, you will feel right at home. The 40mm drivers deliver a “nice, punchy sound” without sounding muddy. While some audiophiles might find the soundstage limited, for the average listener, the crisp vocals and decent thump make music enjoyable.
- Pro Tip: Use the JBL Headphones App. Users praised it for being easy to use and allowing EQ tweaks to match your taste.
3. Lightweight & Foldable
Weighing just 232g, these headphones are incredibly light. Users noted they are comfortable enough to wear for entire work shifts without soreness. The foldable design makes them easy to toss into a bag, though many users complained about the lack of an included carry case.
4. Modern Features: Multipoint & Bluetooth 5.3
Despite the budget price, you get Multipoint Connection, allowing you to switch seamlessly between a video on your tablet and a call on your phone.5 The Bluetooth 5.3 connection is generally stable, though some users faced initial struggles pairing with laptops or TVs.
The Bad: Where It Cuts Corners
1. The “Bus Static” Issue (ANC Limitation)
This is a critical flaw for some commuters. Multiple users reported that while the Noise Cancellation blocks fan noise well, it reacts poorly to heavy vibrations.
- The Issue: On moving vehicles like buses, the headphones can produce a “static cracking sound” as the ANC microphones struggle to process the road bumps and engine rumble.
- Verdict: If your commute involves very bumpy roads, you might have to turn ANC off to avoid this artifact.
2. Comfort & Clamping Force
While many find them comfy, the “Over-Ear” fit is quite snug. Users with larger heads or sensitive ears reported that the headphones “clutch your head,” becoming uncomfortable after 45–60 minutes. One user specifically noted the ear cups are small and may not fully enclose larger ears.
3. Build Quality Concerns
You are paying for the electronics, not premium materials. Long-term owners have reported wear and tear within the first year:
- Hinges: One user reported the turning hinge broke after a year and was not repairable.
- Earpads: The leather covering on the earpads may start peeling or rotting after 12–18 months of extensive use.
4. The AUX Cable Quirk
Several users noted a design annoyance with the wired mode. If you insert the AUX cable fully, audio might only play from one side. You often have to leave the wire “slightly loose” or fiddle with it to get stereo sound.

FAQ: Common User Questions
Q: Is the ANC good enough for flights?
A: It is “decent.” It will block out the hum of an engine or a fan, but don’t expect the silence of a Sony WH-1000XM5. It dampens noise rather than eliminating it.
Q: Can I use them for gaming?
A: Yes, via the AUX cable to avoid latency. Over Bluetooth, there is a “Video Mode” in the app to reduce lag, but serious gamers should always go wired.
Q: Do they leak sound?
A: They are closed-back, so sound leakage is minimal at normal volumes.6 However, at volumes above 85%, some distortion and leakage can occur.
Final Thoughts
The JBL Tune 770NC is a textbook example of a great mid-range product. It isn’t trying to be a luxury item; it’s trying to be a reliable daily driver.
If you can forgive the plastic build and the occasional ANC hiccup on bumpy roads, you are getting sound quality and battery life that rivals headphones twice the price.
Buy it if: You want the best battery life in the class and punchy bass for the gym or office.
Don’t buy it if: You need industrial-strength noise cancellation or premium metal build quality.
