JBL Tune 670NC Review: Huge Battery, Solid ANC—8/10
“Battery lasts forever” is the phrase that keeps surfacing around the JBL Tune 670NC Wireless On-Ear Headphones (Black). Across store reviews and pro write‑ups, the headline is a long‑running, commuter‑friendly set of on‑ears with surprisingly capable noise canceling for the form factor—tempered by a few recurring caveats about loudness, fit pressure, and occasional pairing quirks. Overall verdict based on the collected feedback: a strong budget pick with specific tradeoffs. Score: 8/10.
Quick Verdict
Conditional Yes. The feedback paints these as lightweight, easy everyday headphones with standout battery life and good ANC for the price, but not for people who need booming bass, very high volume, or all‑day on‑ear comfort.
| What users highlight | Evidence from feedback | Who it matters to |
|---|---|---|
| Excellent battery life | Best Buy user ChristopherG said: “battery lasts very long time… i forget to turn it off and its still ready.” | Travelers, students, daily commuters |
| Comfort for short/medium sessions | Best Buy user Susans said: “very comfortable and easy on my ears.” | Office users, casual listeners |
| Noise canceling beats expectations for on‑ear | Best Buy user EssieW said ANC “cancelled out a significant amount of noise” even without music. | Studying, open‑office work |
| Sound is clear but can feel quiet | TechRadar noted audio is “pretty quiet,” and Best Buy user ToddR said, “The volume could be higher.” | People who listen loud or in noisy areas |
| Fit can be tight/clampy for some | Expert Reviews warned “not comfortable during prolonged use,” citing strong clamping force. | Long sessions, large heads |
| Occasional connectivity hiccups | Best Buy user Pun Kyiv said they “sometimes… don’t pair with my iPhone.” | iPhone users, multipoint switchers |
Claims vs Reality
JBL markets the JBL Tune 670NC around “up to 70 hours” of battery life, adaptive noise canceling, and “Pure Bass Sound.” Digging deeper into user reports, two of those claims line up strongly, while one lands more unevenly.
Battery life is where marketing and lived experience align most tightly. The spec sheet promises up to 70 hours with ANC off and 44 hours with ANC on, and multiple users describe week‑long stamina in real life. Best Buy user EssieW said: “I’ve used them daily for three months straight and have charged them about 3x total.” Another verified Best Buy reviewer, ChristopherG, echoed that they last so long he forgets to power them down. Even professional coverage reinforces this; TechRadar called battery life “phenomenal” and Expert Reviews labeled it “excellent.”
Adaptive noise canceling is also generally validated, with context. JBL positions ANC as a focus tool, and several buyers describe a pronounced drop in background noise. Best Buy user Susans praised “awesome noise canceling quality,” while EssieW emphasized studying benefits: “sometimes… activate the feature without turning on any music and it still cancelled out a significant amount of noise.” Expert Reviews similarly found ANC “impressive… for on‑ear headphones,” noting it muffles nearby phone audio even without music. The gap is that on‑ear design still leaks more environment than over‑ear models; TechRadar explicitly called ANC “average” outdoors, and described traffic bleed‑through on busy roads.
“Pure Bass Sound” is the claim where reports diverge. Some listeners are thrilled after EQ tweaks, while others feel the default sound is soft. Best Buy user Naginalf said: “using the eq to boost bass, these… will rattle your eardrums out.” But TechRadar and Expert Reviews both describe bass as weaker or needing adjustment, with TechRadar saying “weak bass” and “audio is pretty quiet.” While marketing frames bass as a signature trait, several reviewers imply you’ll want to lean on the app EQ to get the low‑end character you expect from JBL.
Cross-Platform Consensus
Universally Praised
A recurring pattern emerged around the practical, everyday nature of the JBL Tune 670NC. Many buyers frame them as a no‑fuss daily driver that “just works” for commute, study, and office tasks. Ease of pairing and general usability show up repeatedly. Best Buy user Susans said they were “easy to pair with my devices,” and JoelB called them “light weight… pretty durable for daily use.” For users hopping between a phone and laptop, the multipoint/wired flexibility is part of the appeal. Best Buy user JeffryR described switching contexts—“wired… on an airplane or bluetooth… for phone, tv or dap”—as central to why he was “extremely pleased.”
Battery endurance isn’t just a spec line in user stories; it’s framed as lifestyle freedom. Students and professionals mention charging only occasionally. EssieW, studying for the bar exam, said she charged roughly three times in three months of daily use. Amit Kumar described office calling and gaming without needing a recharge “for quite a long time.” That kind of stamina changes habits for commuters who don’t want another device to manage.
Comfort and portability are another shared positive, especially for short to medium sessions. Several users emphasize how light they feel and how easily they store. Best Buy user Bren Kay praised that they “fold up well so i can tuck it in my purse easily,” and CarolK liked the fit even though it was “a little tight.” TechRadar similarly leaned on portability, noting the headphones fold easily and are “very portable, lightweight.” The implication for travelers and students is a set of ANC headphones you can actually toss into a bag without feeling the weight.
Noise canceling quality is consistently praised relative to price. Best Buy user Scotty called out “great noise reduction… at an affordable price,” and EssieW described ANC as “incredible” for blocking distractions while studying. Expert Reviews’ pro assessment mirrors this, stating ANC “exceeded my expectations” for on‑ear cans. For office workers or exam preppers, that level of isolation at a sub‑$100 sale price is a core reason many recommend them.
Common Complaints
The most frequent critique is volume and out‑of‑box sound strength. Multiple sources describe the JBL Tune 670NC as a bit quiet unless you push levels or tune EQ. Best Buy user ToddR said plainly, “The volume could be higher.” TechRadar’s reviewer reported that sound was “quiet and subdued,” and Expert Reviews admitted they kept turning the volume up to around 70% to get clarity. For listeners in loud environments—public transit, busy streets—this means you may hit your comfortable maximum earlier than on louder competitors.
Fit pressure and long‑session comfort come up next. On‑ear designs already polarize, and these appear to clamp firmly. Expert Reviews described a “muscular clamping force” that made ears ache “after less than an hour.” CarolK called them “a little tight,” expecting break‑in to help. This doesn’t stop people from liking them, but it flags a risk for anyone who wants all‑day wear, larger heads, or very soft clamp.
A third recurring issue is occasional Bluetooth pairing inconsistency, particularly with iPhones. Best Buy user Pun Kyiv said that “sometimes they don’t pair with my iphone.” The broader set of Best Buy reviews rates connectivity high overall, but that one‑line frustration is echoed enough to note a pattern: most users connect easily, but a minority see sporadic hiccups. For heavy multipoint users, a rare reconnect moment can still be annoying.
Sound leakage at higher volumes is another smaller but repeated point. Best Buy user JBM 1203 said the only downside was that “when playing at a higher volume, it can be heard by others.” This matters for shared spaces like libraries or open offices; you may need to keep volume moderate to avoid bleed.
Divisive Features
Bass response divides listeners sharply. Some love the low end once tuned, while others find it weak by JBL standards. Naginalf praised EQ‑boosted bass that can “rattle your eardrums,” but TechRadar called bass “positively weak,” suggesting the default profile doesn’t satisfy bass‑first buyers. The divide often maps to user type: casual pop/podcast listeners are content, while bass‑centric music fans expect more without tweaking.
Ambient modes and controls also split opinion. Some users like the dramatic switch between ANC and awareness. Best Buy user DebraR said the change was “so drastic… i love being able to switch if i want to.” But Naginalf found talk‑through and awareness less useful in practice: “don’t expect to hear someone talking to you unless the volume is very low… talkthru… completely useless.” The feature works, but expectations about how much you’ll actually hear through music vary.
Trust & Reliability
Trustpilot‑listed feedback in the provided data mirrors Best Buy, so scam concerns don’t surface prominently in this set. Instead, reliability talk focuses on day‑to‑day durability. Best Buy user JoelB called them “pretty durable for daily use,” and JonathanG shared a rough‑use anecdote: “water fell on him and nothing happened to him.” Another Best Buy reviewer noted her husband uses them during outdoor chores and they’re “holding up very well.” While these are shorter‑term stories, they point toward resilience for commuting and light outdoor use.
Long‑term “six months later” threads from Reddit aren’t present in the dataset, so the clearest durability signals remain these mid‑term buyer experiences and the professional caution from Expert Reviews that they “feel cheap” and may scratch over time without a case. That’s a contradiction worth flagging: while some users report solid durability, at least one pro reviewer warns the plastic build doesn’t inspire confidence.
Alternatives
Only competitors mentioned in the data are Sony WH‑CH720N, Anker Soundcore Life Q30, Marshall Major IV, Jabra Elite 45h, and 1More Sonoflow. Pro reviewers position the JBL Tune 670NC as the portability and battery champion among these, but not the strongest for sound.
TechRadar compared them directly, saying they’d “favor the Sony WH‑CH720N” for better sound, while acknowledging the JBLs are “more portable.” Expert Reviews suggested Marshall Major IV or Jabra Elite 45h if comfort or audio quality is the priority, and 1More Sonoflow as a cheaper over‑ear with “improved noise cancellation.” The implied takeaway from cross‑source feedback: pick the JBLs when you care most about light on‑ear carry and marathon battery, but consider Sony or Anker if you want fuller sound or over‑ear isolation.
Price & Value
Price talk in user reviews is unusually enthusiastic for the JBL Tune 670NC, partly because many bought on sale. Best Buy pricing in the data shows $69.95 sale vs $109.95 comparable value, and multiple reviewers mention discount as a key factor. Amit Kumar called his 50%‑off purchase “a perfect treat,” and ToddR framed his recommendation around a similar deal: “got for 50% off. would recommend.”
Resale and market pricing from eBay listings suggest new units often sit around $65–$80, reinforcing the idea that these frequently sell below MSRP. For budget shoppers, that lines up with repeated “for the price” endorsements—JoelB: “good noise canceling for the price,” Scotty: “affordable price,” and CarolK: “great headphones for the price.” The community’s buying tip embedded in those stories is simple: value spikes when you catch a sale, because you’re getting long battery life and competent ANC at entry‑level cost.
FAQ
Q: Do the JBL Tune 670NC really last close to 70 hours?
A: Yes for many users when ANC is off, and still very long with ANC on. Best Buy user EssieW said she charged only “about 3x” in three months of daily use, and ChristopherG noted the battery stays ready even if he forgets to turn them off.
Q: How strong is the noise canceling on these on-ear headphones?
A: Strong for the price and form factor, but not total silence. Best Buy user Susans praised “awesome noise canceling quality,” and EssieW said ANC alone “cancelled out a significant amount of noise.” TechRadar and Expert Reviews add that busy streets still leak through because they’re on‑ear.
Q: Is the sound bass-heavy like other JBL models?
A: It depends on your expectations and EQ use. Best Buy user Naginalf said EQ‑boosted bass can “rattle your eardrums,” but TechRadar described bass as “weak” out of the box. Many listeners are happy, but bass‑first buyers may need tuning.
Q: Are they comfortable for long sessions?
A: Comfort is good for many, but clamp can bother some over time. Susans called them “very comfortable,” while Expert Reviews said strong clamping made ears ache after under an hour. CarolK described a “little tight” fit that may loosen with use.
Q: Any connectivity issues with iPhones?
A: Mostly easy pairing, with occasional reports of hiccups. Pun Kyiv noted they “sometimes… don’t pair with my iphone,” but several others said pairing was quick and simple. Expect generally reliable Bluetooth with rare annoyances.
Final Verdict
Buy if you’re a commuter, student, or office worker who wants lightweight on‑ears with long battery life and effective noise canceling at a budget price. Avoid if you need very loud output, deep bass without EQ, or all‑day clamp‑free comfort. Pro tip from the community: watch for the frequent sales—many of the strongest recommendations come from people who grabbed them at roughly half price.
