Has Passive Noise Reduction

Sennheiser HD 350BT ✓

JBL Tune 520BT ✓

Passive Noise Cancellation uses well-designed ear cups to seal out unwanted 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.

Both of these devices have passive noise reduction which means that also the JBL Tune 520BT isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Sennheiser HD 350BT 18Hz

JBL Tune 520BT 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. Sennheiser HD 350BT's lowest frequency is at 18Hz, the lower the low-frequency response, the stronger and juicier the bass.

JBL Tune 520BT's lowest frequency is at 20Hz, this means that JBL Tune 520BT got a juicier bass than the Sennheiser HD 350BT

Highest Frequency

Sennheiser HD 350BT 22,000Hz

JBL Tune 520BT 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 on the way through. Sennheiser HD 350BT's highest frequency is at 22,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

JBL Tune 520BT's highest frequency is at 20,000Hz, this means that Sennheiser HD 350BT got a clearer and crispier treble than the JBL Tune 520BT

Sound Pressure Level

Sennheiser HD 350BT 108dB/mW

JBL Tune 520BT 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 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, Sennheiser HD 350BT's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

JBL Tune 520BT's sound pressure level measurement is 103dB/mW.

Driver Unit Size

Sennheiser HD 350BT 32mm

JBL Tune 520BT 30mm

The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Sennheiser HD 350BT driver unit is 32mm in diameter, bigger drivers are more powerful and can produce better bass.

JBL Tune 520BT driver unit is 30mm in diameter, which means that they have a smaller driver unit than that of Sennheiser HD 350BT by 2mm , 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 yeah, larger drivers can generate louder sound, but this does not mean that they deliver better sound.

Impedance

Sennheiser HD 350BT 32Ohms

JBL Tune 520BT 32Ohms

Defined as the device's resistance to the electromagnetic current, as electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Sennheiser HD 350BT's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

JBL Tune 520BT's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.

Has A Neodymium Magnet

Sennheiser HD 350BT ✓

JBL Tune 520BT ✗

Neodymium magnets when 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.
