JBL Tune 670NC have stereo speakers, devices with stereo speakers deliver sound from separate channels on both left and right sides, creating a richer sound and a better listening experience. Both Sennheiser HD 350BT and JBL Tune 670NC have stereo speakers
Active noise cancellation uses more advanced technology to actively counter noise.
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 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.
Low-frequency response measures if and how well a particular 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. Sennheiser HD 350BT's lowest frequency is at 18Hz, this means that
JBL Tune 670NC got a juicier bass than the Sennheiser HD 350BT

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 the means to get 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. 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. Sennheiser HD 350BT driver unit is 32mm in diameter,
making both devices 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 can generate louder sound, but this does not mean that they deliver better sound.
Impedance is the device's resistance to the electromagnetic current, when electricity flows through a wire, 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. 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.
