Sennheiser Hd 350Bt Vs. Sony Wh Ch520 Review In Detail

Design

Weight

Sennheiser HD 350BT 238g
Sony WH CH520 147g

The Sennheiser HD 350BT have a weight of 238g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We consider a lower weight best because lighter devices are more comfortable to transport.

Sony WH CH520, at 147g weigh less than the Sennheiser HD 350BT with a difference -91g

Can Be Folded

Sennheiser HD 350BT
Sony WH CH520

Sennheiser HD 350BT are foldable, which makes them more portable. Foldable headphones are easier to transport and take up less storage space.

Has A Tangle Free Cable

Sennheiser HD 350BT
Sony WH CH520

Twisted headphone cables can be a great source of annoyance and inconvenience, Sony WH CH520'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 completely damaging your headphones.

Sweat Resistance

Sennheiser HD 350BT
Sony WH CH520

By sweat resistance we mean that the wireless earbuds are protected in the presence of low-pressure water jets at any angle, this is determined by the IP Rating of the earbuds. Based on the ingress protection rating of the Sony WH CH520 they do have sweat resistance

Has An Over-The-Ear Foam

Sennheiser HD 350BT
Sony WH CH520

Over-ear headphones have larger earpads that fit around your entire ear Sennheiser HD 350BT 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.

Has An On-Ear Foam

Sennheiser HD 350BT
Sony WH CH520

On-ear headphones have smaller earpads that sit on top of your ears, this Sony WH CH520 comfortably rests on top of your outer ears. As it doesn't block out everything from the outside world, it's preferred in places like office environments and recommended for outdoor activities.

Has Stereo Speakers

Sennheiser HD 350BT

Sound Quality

Has Passive Noise Reduction

Sennheiser HD 350BT
Sony WH CH520

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 Sony WH CH520 isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Sennheiser HD 350BT 18Hz
Sony WH CH520 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 on the way through. Sennheiser HD 350BT's lowest frequency is at 18Hz, the lower the low-frequency response, the stronger and juicier the bass.

Sony WH CH520's lowest frequency is at 20Hz, this means that Sony WH CH520 got a juicier bass than the Sennheiser HD 350BT

Highest Frequency

Sennheiser HD 350BT 22,000Hz
Sony WH CH520 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.

Sony WH CH520's highest frequency is at 20,000Hz, this means that Sennheiser HD 350BT got a clearer and crispier treble than the Sony WH CH520

Sound Pressure Level

Sennheiser HD 350BT 108dB/mW
Sony WH CH520 97dB/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.

Sony WH CH520's sound pressure level measurement is 97dB/mW.

Driver Unit Size

Sennheiser HD 350BT 32mm
Sony WH CH520 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.

Sony WH CH520 driver unit is 30mm in diameter, which means that they have a smaller driver unit than that of Sennheiser HD 350BT by 2mm , 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 yeah, larger drivers can generate louder sound, but this does not mean that they deliver better sound.

Impedance

Sennheiser HD 350BT 32Ohms
Sony WH CH520 35Ohms

Defined as the device's resistance to the electromagnetic current, as electricity flows through a wire, 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.

Sony WH CH520's impedance is 35Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.

Has A Neodymium Magnet

Sennheiser HD 350BT
Sony WH CH520

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.

Sony WH CH520 have it too, devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. It is also known that they have more bass and clear high notes.

Power

Battery Life

Sennheiser HD 350BT's battery life is 30 hours

Sony WH CH520's battery life is 40 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.
