JBL Live 670NC Overview

The JBL Live 670NC is JBL’s mid range on ear wireless headphone. It launched in 2024 and quickly earned strong reviews for its long battery life and bass heavy sound. The headphone uses 40mm dynamic drivers and supports Bluetooth 5.3 with LE Audio.

You get True Adaptive Noise Cancelling with Smart Ambient mode. This means the ANC adjusts based on your surroundings. The Smart Ambient feature lets outside sound in when you need to hear traffic or a coworker. The headphones also fold flat, making them easy to pack.

The JBL Headphones app gives you a 10 band equalizer, Spatial Sound options, and firmware updates. You also get hands free Alexa support and multipoint Bluetooth pairing. Battery life reaches 65 hours with ANC off and around 50 hours with ANC on.

Pros

• Outstanding 65 plus hour battery life

• Adjustable EQ inside the JBL app
• Bluetooth 5.3 with multipoint pairing
• Fast charge gives 4 extra hours in 5 minutes

Cons

• ANC is only average for road and plane noise
• Mic quality is below average for calls
• On ear fit may pinch during long sessions

JBL Live 675NC Overview

The JBL Live 675NC is a near twin of the 670NC. It mostly appears at Costco and select retailers as a model number variant. Many buyers on Reddit and YouTube confirm the 675NC pairs through the JBL app the same way the 670NC does.

The headphone delivers JBL Signature Sound through 40mm drivers. You also get Bluetooth 5.3, LE Audio, Auto Play and Pause, and True Adaptive Noise Cancelling. The design is folding, lightweight, and on ear. Battery life is rated at 65 hours without ANC and 50 hours with ANC on.

The 675NC is often bundled or boxed for warehouse club shoppers. Costco listed it around 70 dollars, which is a real bargain. Some users feel the ear pads are a bit small for larger ears, but the sound quality stands out at this price.

Pros

• Lower price tag at Costco style retailers
• 65 hour battery life with fast charging
• True Adaptive Noise Cancelling included
• Great sound for the cost
• Works with JBL Headphones app

Cons

• Limited online reviews and information
• Smaller ear pads may feel tight
• Harder to find outside warehouse stores

Design and Build Quality Compared

Both headphones share the exact same on ear design. They use a soft cushioned headband with synthetic leather ear pads. The hinges fold inward so you can slip them into a backpack pocket. The build is mostly plastic, but it feels solid and not cheap.

The JBL logo sits on each ear cup. Color options include black, blue, white, and sandstone for the 670NC. The 675NC is mostly available in black at Costco. Both weigh around 219 grams, which is light for daily wear.

You will find a USB C charging port and a 3.5mm headphone jack on the left ear cup. This wired option is great when the battery dies or for use on a plane. The right ear cup holds the physical control buttons. Both models score a near identical look and feel in person.

Sound Quality Showdown

The sound profile is identical between the two models. Both rely on 40mm dynamic drivers tuned with JBL Signature Sound. Expect a bass forward sound with punchy lows and clear vocals. The mids feel slightly recessed, which is normal for consumer tuned headphones.

You can tweak the sound through the JBL Headphones app. The 10 band EQ lets you boost treble or reduce bass. Spatial Sound creates a wider soundstage for movies and games. Both headphones support this feature equally.

Users on Reddit even compared the 675NC to the Sony WH 1000XM5 and felt the sound was close in casual listening. Of course, the Sony costs four times more. For pop, hip hop, EDM, and podcasts, both JBL models perform well. Audiophiles may want flatter tuning, but most listeners will love the bass.

Noise Cancelling Performance

Both the JBL Live 670NC and 675NC use True Adaptive Noise Cancelling. This system measures outside noise and adjusts the ANC strength in real time. It works well for steady sounds like air conditioners, fans, and engine hum.

The Smart Ambient mode lets in surrounding sound with one tap. This is helpful when ordering coffee or crossing the street. Both models offer the same ANC chip and microphones, so performance is identical.

Reviewers like PCMag and RTINGS note that ANC on the 670NC is passable but not class leading. Sharp voices and high pitch sounds still slip through. Over ear models like the JBL Live 770NC do a better job for plane travel. Still, for the price, the ANC is solid for buses, gyms, and offices.

Battery Life Differences

This is one area where the two headphones may differ slightly. Both list 65 hours with ANC off and 50 hours with ANC on. RTINGS measured the JBL Live 670NC at a record breaking 88 hours in real testing. That is one of the longest battery results for any wireless headphone.

The 675NC has fewer test reports online. Some Reddit users say charging cycles feel a bit shorter. Others say battery life is the same. Without lab tests, the official rating of 65 hours stands for both.

A 5 minute fast charge gives 4 extra hours of playback on each model. The USB C cable is included in the box. If you forget to charge for a week, that is fine. Both models will likely still have power left over.

Bluetooth and Connectivity

Both headphones run Bluetooth 5.3 with LE Audio support. This means lower latency, better range, and improved energy use. You can pair to two devices at once using multipoint Bluetooth.

You also get Auto Play and Pause. This feature stops music when you remove the headphones from your head. It restarts when you put them back on. Both models include this sensor.

Voice assistants are easy to use. Hands free Amazon Alexa works through a hot word or a tap on the ear cup. Google Assistant and Siri both work too. Connection range is around 10 meters in open spaces. In tests, both models hold a stable signal even with the phone in another room.

Comfort and Fit Test

The on ear style of these JBL headphones can be a love or hate feature. Some users find them light and easy to wear all day. Others say the ear cups press on the ear and cause pain after about an hour.

Both models share the same headband padding and ear cup size. So if one feels tight, the other will too. Reviewers on Reddit mentioned the ear pads are smaller than expected. People with larger ears may want to try them in store first.

The 219 gram weight helps keep neck strain low. The clamping force is firm enough to stay on during walking, but not strong enough for running or heavy workouts. For office use, study, and commuting, both feel comfortable enough.

Microphone and Call Quality

Call quality is a weak point for both headphones. The JBL Live 670NC and 675NC use the same dual mic setup. PCMag and RTINGS both rated the mic as below average. Voices come through clearly in quiet rooms, but background noise leaks in.

If you take many phone calls or join meetings, you may want to consider an over ear model. The JBL Live 770NC or Tour One M2 do a better job for voice calls.

For casual calls and quick chats, the mic is fine. Both models handle wind noise about the same. Bluetooth latency is low enough for normal calls. Just do not expect studio level voice clarity from these mid range headphones.

App Features and Customization

Both headphones work with the JBL Headphones app on iPhone and Android. The app shows battery level, ANC mode, and current EQ setting. You can also rename the device and adjust Spatial Sound.

The 10 band EQ is useful for fine tuning sound. There are also preset EQ modes like Bass, Vocal, and Studio. Firmware updates roll out through the app and add small fixes over time.

You also get Personi Fi 2.0 in the app. This feature creates a custom sound profile based on your hearing test. It works on both the 670NC and 675NC equally. Other tools include Auto Off Timer, voice prompt language, and remap of the action button.

Price and Value Comparison

Price is where the two models split clearly. The JBL Live 670NC sells for around 100 to 130 dollars on Amazon. It often goes on sale for under 90 dollars during holiday events.

The JBL Live 675NC is mostly a Costco product. Reddit users report buying it for around 70 dollars in store. This price drop makes the 675NC the better value if you have a Costco membership.

If you do not have a warehouse club nearby, the 670NC is easier to find online. Returns and warranty support are also simpler through Amazon. The two headphones are nearly identical in features, so the cheaper one wins on pure value.

Who Should Buy the JBL Live 670NC

Pick the JBL Live 670NC if you shop online and want easy delivery. This model is widely stocked on Amazon, Best Buy, and the JBL website. You get fast Prime shipping, easy returns, and many color options.

It is also a good fit for students, commuters, and remote workers. The 65 hour battery life means you charge once a week. The light foldable design fits in a backpack with no fuss.

Pros

• Wide online stock and easy shipping
• Up to 65 hours of battery life
• Several color choices
• Strong app support and EQ tools
• Bluetooth 5.3 with multipoint

Cons

• Costs more than the 675NC

This model is also great for gift buyers and budget shoppers. The sound quality matches the 670NC and the JBL app works the same. Gamers on Reddit even praised the low latency for casual gaming.

Final Verdict: 670NC or 675NC?

Both headphones come from the same family. They share drivers, ANC, Bluetooth, app features, and battery rating. The main split is where you buy them and how much you pay.

If you want the easiest shopping experience, go for the JBL Live 670NC on Amazon. You get full color choice, fast shipping, and strong return policy. It also has more reviews online to help you decide.

If you want the best price and have access to Costco, the JBL Live 675NC wins. You save real money while getting nearly the same headphone. Either way, you end up with a solid pair of on ear wireless headphones with great battery life and good sound.
