Jbl Tune 670Nc Vs. Jbl Tune 720Bt Review In Detail

Design

Weight

JBL Tune 670NC 174g
JBL Tune 720BT 220g

The JBL Tune 670NC have a weight of 174g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We take in account a lower weight best for the reason that lighter devices are more comfortable to move with.

JBL Tune 720BT, at 220g weigh more than the JBL Tune 670NC by 46g

Has A Detachable Cable

JBL Tune 670NC
JBL Tune 720BT

Detachable cables are cables that have connectors on both ends. One end goes into your headphone earpieces, while the other end is inserted into an audio source. Some new headphones, and not just the expensive ones, are coming with detachable cables, JBL Tune 670NC are one of those.

With a detachable cable, JBL Tune 720BT too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.

Can Be Folded

JBL Tune 670NC
JBL Tune 720BT

JBL Tune 670NC are foldable, which makes them more portable. Foldable headphones are easier to transport and take up less storage space.

Has A Tangle Free Cable

JBL Tune 670NC
JBL Tune 720BT

Twisted headphone cables can be a great source of annoyance and inconvenience, JBL Tune 670NC's cable is designed to minimize tangling. Constant twisting of the cables can also lead to microfractures in the copper wires, affecting sound quality, or rendering your headphones defective.

JBL Tune 720BT too have a cable designed to help prevent tangles.

Cable Length

JBL Tune 670NC 1.2meters
JBL Tune 720BT 1.2meters

A long cable ensures more freedom of movement, but remember that every cable based on the conducting material used has a certain amount of parasitic resistance, inductance, and capacitance. How much depends on the length and construction. JBL Tune 670NC comes with a 1.2meters cable.

JBL Tune 720BT comes with a 1.2meters cable. Almost any cable should be fine in sound quality If you're looking at lengths up to 2 - 3 meters.

Has An Over-The-Ear Foam

JBL Tune 670NC
JBL Tune 720BT

Over-ear headphones have larger earpads that fit around your entire ear JBL Tune 670NC have a comfortable full-size form with earcups that fully enclose your ears. This design is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors.

JBL Tune 720BT with this design offer potential for maximum bass and loudness levels.

Has Stereo Speakers

JBL Tune 670NC
JBL Tune 720BT

JBL Tune 670NC have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience.

The JBL Tune 720BT also have stereo speakers

Sound Quality

Has Active Noise Cancellation (Anc)

JBL Tune 670NC
JBL Tune 720BT

Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 outside (noise from your surrounding) and adding -1 inside (counter sound within the device) to make 0 hence "diluting" the noise.

JBL Tune 670NC allow you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise.

Has Passive Noise Reduction

JBL Tune 670NC
JBL Tune 720BT

Passive Noise Cancellation uses well-designed ear cups to seal out environment noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out. The JBL Tune 720BT sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.

Lowest Frequency

JBL Tune 670NC 20Hz
JBL Tune 720BT 20Hz

Low-frequency response measures if and how well an audio device reproduces low audible frequencies and if it makes any changes to the signal while at it. JBL Tune 670NC's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.

JBL Tune 720BT's lowest frequency is at 20Hz, this means that both devices produce equal bass

Highest Frequency

JBL Tune 670NC 20,000Hz
JBL Tune 720BT 20,000Hz

High frequency response measures if and how well an audio device reproduces high audible frequencies and if it makes any changes to the signal while at it. JBL Tune 670NC's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

JBL Tune 720BT's highest frequency is at 20,000Hz, this implies that both devices produce equal treble

Sound Pressure Level

JBL Tune 670NC 98dB/mW
JBL Tune 720BT 103dB/mW

Sound pressure is the average variation in atmospheric pressure caused by the sound, the sound level .i.e how loud something is can be perceived differently by different people so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.

The sound pressure level, SPL, is the pressure level of a sound, measured in decibels, dB, JBL Tune 670NC's measurement is 98dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

JBL Tune 720BT's sound pressure level measurement is 103dB/mW.

Driver Unit Size

JBL Tune 670NC 32mm
JBL Tune 720BT 40mm

The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. JBL Tune 670NC driver unit is 32mm in diameter, bigger drivers are more powerful and can produce better bass.

JBL Tune 720BT driver unit is 40mm in diameter, making them have a larger driver unit than that of JBL Tune 670NC by 8mm , many people have a misconception that driver units of a bigger size automatically produce better sound quality.

However, large drivers usually have difficulty reproducing high frequencies so yes, larger drivers can generate louder sound, but this does not mean that they deliver better sound.

Impedance

JBL Tune 670NC 32Ohms
JBL Tune 720BT 32Ohms

Defined as the device's resistance to the electromagnetic current, when electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. JBL Tune 670NC's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

JBL Tune 720BT's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.

Power

Battery Life

JBL Tune 670NC 70hours
JBL Tune 720BT 76hours

If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time.
