Jbl Tune 670Nc Vs. Sennheiser Hd 350Bt Review In Detail

Design

Weight

JBL Tune 670NC 174g
Sennheiser HD 350BT 238g

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 prefer a lower weight better because lighter devices are more comfortable to move with.

Sennheiser HD 350BT, at 238g weigh more than the JBL Tune 670NC by 64g

Has A Detachable Cable

JBL Tune 670NC
Sennheiser HD 350BT

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.

Can Be Folded

JBL Tune 670NC
Sennheiser HD 350BT

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

The Sennheiser HD 350BT too can fold up, foldable headphones can reduce their size by 60% to 70% when folded.

Has A Tangle Free Cable

JBL Tune 670NC
Sennheiser HD 350BT

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 bends in the copper wires, affecting sound quality, or completely damaging your headphones.

Cable Length

JBL Tune 670NC 1.2meters
Sennheiser HD 350BT

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.

Has An Over-The-Ear Foam

JBL Tune 670NC
Sennheiser HD 350BT

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.

Sennheiser HD 350BT with this design offer potential for maximum bass and loudness levels.

Has Stereo Speakers

JBL Tune 670NC
Sennheiser HD 350BT

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

The Sennheiser HD 350BT also have stereo speakers

Sound Quality

Has Active Noise Cancellation (Anc)

JBL Tune 670NC
Sennheiser HD 350BT

Active noise cancellation uses more advanced technology to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and then generates a mirror signal 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 zero 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
Sennheiser HD 350BT

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 Sennheiser HD 350BT 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
Sennheiser HD 350BT 18Hz

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

Sennheiser HD 350BT's lowest frequency is at 18Hz, this means that JBL Tune 670NC got a juicier bass than the Sennheiser HD 350BT

Highest Frequency

JBL Tune 670NC 20,000Hz
Sennheiser HD 350BT 22,000Hz

High frequency response measures if and how well a particular 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.

Sennheiser HD 350BT's highest frequency is at 22,000Hz, this implies that Sennheiser HD 350BT got a clearer and crispier treble than the JBL Tune 670NC

Sound Pressure Level

JBL Tune 670NC 98dB/mW
Sennheiser HD 350BT 108dB/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.

Sennheiser HD 350BT's sound pressure level measurement is 108dB/mW.

Driver Unit Size

JBL Tune 670NC 32mm
Sennheiser HD 350BT 32mm

The driver unit is basically a mini speaker 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.

Sennheiser HD 350BT driver unit is 32mm in diameter, making both Sennheiser HD 350BT, and JBL Tune 670NC similar in how loud their sound gets , as many tend to believe 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 are capable of generating louder sound, but this does not mean that they deliver better sound.

Impedance

JBL Tune 670NC 32Ohms
Sennheiser HD 350BT 32Ohms

Impedance is the device's resistance to the electromagnetic current, as 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.

Sennheiser HD 350BT's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.

Has A Neodymium Magnet

JBL Tune 670NC
Sennheiser HD 350BT

Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Sennheiser HD 350BT have this type of magnet.

Power

Battery Life

JBL Tune 670NC 70hours
Sennheiser HD 350BT 30hours

If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time. The device's battery life is given by the manufacturer, with longer battery life, you get to use it for longer and have to charge the device less often. JBL Tune 670NC's battery life is 70 hours

Sennheiser HD 350BT's battery life is 30 hours. Each time you recharge your headphones, they get a little less listening time. The effect is barely noticeable at first. But over a few years, you may find that your device, no longer plays for long like it used to.
