Detachable cables are cables that have connectors on both ends. One end goes into your headphone cups, while the other end is inserted into an audio source. Some new headphones, and not just the expensive ones, are coming with detachable cables, Sennheiser HD 450BT are one of those.
With a detachable cable, JBL Tune 750BTNC too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.
Sennheiser HD 450BT are foldable, which makes them more portable. Foldable headphones are easier to transport and take up less storage space.
The JBL Tune 750BTNC too can fold up, foldable headphones can reduce their size by 60% to 70% when folded.
Twisted headphone cables can be a great source of annoyance and inconvenience, Sennheiser HD 450BT's cable is designed to minimize tangling. Constant twisting of the cables can also lead to bends in the copper wires, affecting sound quality, or rendering your headphones defective.
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 JBL Tune 750BTNC they do have sweat resistance
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. Sennheiser HD 450BT comes with a 1.5meters cable.
Over-ear headphones have larger earpads that fit around your entire ear Sennheiser HD 450BT 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 750BTNC with this design offer potential for maximum bass and loudness levels.
Sennheiser HD 450BT 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.
The JBL Tune 750BTNC also 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 generates a mirror signal 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 0 hence "diluting" the noise.
Sennheiser HD 450BT 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.
JBL Tune 750BTNC too have active noise cancellation making both devices ideal for plane rides and morning commutes. Each may work with different noise cancellation modes, pick the setting, mode, or noise cancellation type that suits your commute or that enhances your relaxation time.
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 450BT 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 750BTNC isolates you from ambient noise instead of actively using technology to cancel it out.
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 450BT's lowest frequency is at 18Hz, the lower the low-frequency response, the stronger and juicier the bass.
JBL Tune 750BTNC's lowest frequency is at 20Hz, this implies that
JBL Tune 750BTNC got a juicier bass than the Sennheiser HD 450BT
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 450BT's highest frequency is at 22,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
JBL Tune 750BTNC's highest frequency is at 20,000Hz, this implies that
Sennheiser HD 450BT got a clearer and crispier treble than the JBL Tune 750BTNC
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 450BT's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Tune 750BTNC's sound pressure level measurement is 100dB/mW.
The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Sennheiser HD 450BT driver unit is 32mm in diameter, bigger drivers are more powerful and can produce better bass.
JBL Tune 750BTNC driver unit is 40mm in diameter,
making them have a larger driver unit than that of Sennheiser HD 450BT 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 deliver better sound.
Impedance is the device's resistance to the electromagnetic current, as electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Sennheiser HD 450BT's impedance is 18Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
JBL Tune 750BTNC'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. Sennheiser HD 450BT's battery life is 30 hours
JBL Tune 750BTNC's battery life is 15 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.
