A breakdown of the review per specifications

Design

Weight

Sennheiser HD 350BT 238g
JBL Tune 720BT 220g

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 better because lighter devices are more comfortable to move with.

The JBL Tune 720BT, at 220g weigh less than the Sennheiser HD 350BT by -18g

Has A Detachable Cable

Sennheiser HD 350BT
JBL Tune 720BT

Detachable cables are cables that have connectors on both ends. One end goes into your headphone cups, while the other end is inserted into a source device. Some new headphones, and not just the expensive ones, are coming with detachable cables, JBL Tune 720BT are one of those.

Can Be Folded

Sennheiser HD 350BT
JBL Tune 720BT

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
JBL Tune 720BT

Twisted headphone cables can be a great source of annoyance and inconvenience, JBL Tune 720BT'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.

Cable Length

Sennheiser HD 350BT
JBL Tune 720BT 1.2meters

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 720BT comes with a 1.2meters cable.

Has An Over-The-Ear Foam

Sennheiser HD 350BT
JBL Tune 720BT

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.

JBL Tune 720BT with this design offer potential for maximum bass and loudness levels.

Has Stereo Speakers

Sennheiser HD 350BT
JBL Tune 720BT

Sennheiser HD 350BT have stereo speakers, what this means is that Sennheiser HD 350BT's speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better listening experience.

The JBL Tune 720BT also have stereo speakers

Sound Quality

Has Passive Noise Reduction

Sennheiser HD 350BT
JBL Tune 720BT

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 720BT isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Sennheiser HD 350BT 18hz
JBL Tune 720BT 20hz

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 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 720BT's lowest frequency is at 20Hz, this implies that JBL Tune 720BT got a juicier bass than the Sennheiser HD 350BT

Highest Frequency

Sennheiser HD 350BT 22,000hz
JBL Tune 720BT 20,000hz

High frequency response measures if and how well a particular audio component 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.

JBL Tune 720BT's highest frequency is at 20,000Hz, this implies that Sennheiser HD 350BT got a clearer and crispier treble than the JBL Tune 720BT

Sound Pressure Level

Sennheiser HD 350BT 108db/mw
JBL Tune 720BT 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 720BT's sound pressure level measurement is 103dB/mW.

Driver Unit Size

Sennheiser HD 350BT 32mm
JBL Tune 720BT 40mm

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 720BT driver unit is 40mm in diameter, making them have a larger driver unit than that of Sennheiser HD 350BT by 8mm , 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they produce better sound.

Impedance

Sennheiser HD 350BT 32ohms
JBL Tune 720BT 32ohms

Defined as the device's resistance to the electromagnetic current, when electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a wire 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 720BT'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 720BT

Neodymium magnets when used in audio devices produce a higher sensitivity and substantial sound output while using less power. 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

Sennheiser HD 350BT 30hours
JBL Tune 720BT 76hours

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. Sennheiser HD 350BT's battery life is 30 hours

JBL Tune 720BT's battery life is 76 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.

Charge Time

Sennheiser HD 350BT 2hours
