Comparison table of boAt Bassheads 100 vs 103 vs 220 vs 225 vs 242(Review)
Super bass in-earphones
The frequency response of the earphones reduces the higher frequencies effectively emphasizing the bass frequencies for the listener.
automatically raise the lower frequencies, but above the loudness level of other bass frequency ranges. All the boAt bassheads have Super Extra Bass.
Driver Size in-earphones
Ranges from 8 mm to 15 mm in diameter. The bigger the driver size larger will be a diaphragm, the bass may be a little cleaner. However, headphones with large drivers also tend to struggle in reproducing treble (high frequencies).All the boAt bassheads 10mm driver size
Resistance to the electric current transmitted by the amplifier or effort your source needs to put in order to drive the pair of earphones.Ranges between 8 and 600 ohms. smaller value higher current is supplied which means more power, further, it means lower battery life of devices. Earphones with 16-ohm impedance are good enough for our mobile phones or portable music players. All the boAt bassheads have 16ohm and 32 ohms.
Sensitivity means how loud the earphones will be for a given level from the source
measured with sound pressure the headphone can take in one mW of power or how effectively the earphone converts an electrical signal into an audio signal. The sensitivity of headphone is designed to keep our ears protected
The safe range for the sensitivity of a headphone is 75 dB to 110 dB
The human ear can handle a maximum of 100 dB for 20 minutes or 110 dB for 8 minutes
Frequency response in-earphones
Range of frequencies or musical tones a component can reproduce
The first number in a frequency response spec refers to the deepest bass frequency the headphone can reproduce, the lower the number the better; and the second number refers to the highest frequency the headphone is capable of and the higher the better
Noise Isolation in-earphones
Passive noise control is basically, isolating ambient sound. All the boAt bassheads earphone have passive noise isolation
Active noise cancellation which is a part of the mechanics of a headphone and involves an actual mechanical process (microphones gauging sound and emitting sounds to cancel them out), passive noise cancellation is more about the design.
Padding and more insulation, and earphones that fit most snugly into your ears, cancel out the most noise, passively.
