can anyone explain all these? -Frequency response -Impedance -Sound pressure level -THD, total harmonic distortion
Does better Frequency Response get better sound quality? Does higher sound pressure level get better Bass?
Sorry i'm noob for this all
Frequency Response - Frequency response is the range of sound in Hertz (Hz) that the drivers on headphones can produce. The range of hearing for the average human is between 20 and 20,000 Hz so you want headphones that can cover that range.
THD stands for Total Harmonic Distortion. This is a representation of all of the distortion over a specific signal. THD for headphones, and everything else for that matter, is measured as a percentage. What you need to know is that a lower percentage is better because it means there will be less distortion in the signal. Not all headphone manufacturers put the THD in their specs but now you know what it means when you see it.
SPL stands for sound pressure level and is measured in decibels (dB). This is a measurement of the energy contained in a sound wave and is supposed to take into account how human ears function for the numeric values. kinda like how boomy the item will blast in ur ears
impedance ah.. simply put .. impedance wd refer to obstruction offered to signal (electrical) ..
The impedance tells you basically how much current will flow through a speaker at a certain voltage

Anyone knows if its feasible to repair a headphone which is spoiled (one side doesnt produce sound anymore)
If so, are there any shops around KL which does repair service?
repairs wont (but yet will be for high end phones) be as costly, but if it is still under warranty coverage, then it will be best to repair, otherwaise, do some calculations and make a backup plan for the worse, buying a new one

so which one is recommendable for long hour of music listening? headphone or iem? I only need to turn the volume usually around level 5 or less using my gumstick. but on headphone need to raise the volume till level 15-20. But i think it actually sounds at quite similar volume to my ear.
it all comes down to your comfort, and how long you want to listen in one go
if you want a marathon audio listening, IEM will be comfotable, and mid range or budget IEM will not draw as much power, leading to longer listening sensation
