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

Sennheiser HD 350BT 18Hz

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.

Highest Frequency

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

Sound Pressure Level

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, 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.

Sennheiser HD 350BT 32Ohms

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

Has A Neodymium Magnet

Sennheiser HD 350BT

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.
