How to Identify the Best Wireless Earpiece : 5 Important Earphone Jargons to Know

Wireless Earpiece come in different styles, price tags, and brands; that’s why it is very difficult to find which pair is right for you. Their specifications are very complex and technical, and so you don’t know what this jargon means. So, to make your purchase that little bit easier, we thought we would put together a brief guide of what all the technical earphone jargon means:

Wireless Earpiece in-ear

In-ear earphones are referred to as earphones that sit directly in your ear canal. They come with two key benefits, i.e., they sit closer to your eardrum and fill your ear entrance. That’s why in-ear earphones can effectively seal out the external noise. 

Transducer / Drivers

Often referred to as drivers or transducers, in essence, this is the internal speaker part of the earphones. Most earphones will have one driver with measurements of 9 – 15mm. Single driver earphones of quality may also be referred to as having a full-range or wide-band single driver. 

Twin or Double Driver earphones have two separate speakers in each earphone, taking care of their part of the sound range, usually a woofer for the lows and a tweeter for the highs. Typically the earphone body is slightly larger, as is the cost, but the sound is far superior to that of a single driver earphone.


Measured in ohms, it’s the amount of resistance that is produced by the internal parts of the earphone – In terms of how this affects the earphone, basically, the lower the resistance; the easier it will be for your music player (phone, laptop, iPod, etc.) to produce the sound that you hear. So, a wireless earpiece with low resistance can play at a lower volume for comfortable hearing, whereas an earphone with higher resistance will need to be turned up to achieve the same volume level. Earphones & Headphones for portable use, e.g., with a phone, mp3 player, iPod, or laptop, would typically have a resistance of 16 or 32 Ohms.

Frequency Response

 Frequency Response is a measure of the range of sound that the earphones will produce, shown in Hertz (Hz) – Most earphones will produce sound between 20 – 18,500 Hz. The frequency range for simplicity is split into 3 main regions:

 • Lows, e.g., Kick Drum or Bass Guitar

 • Mids, e.g., Snare or Vocals

 • Highs, e.g., High Hats, Violins or James Blunt

Earphones will produce sound above 18,500 Hz and below 20 Hz; however, usually as the overall range is increased outside of these points, the price typically increases also; a point to note is that having an earphone with a range over 18,500 Hz has no real benefit as you are pushing the boundaries of what the human ear can process – Just as importantly at each end of the range as you approach the end the volume (or SPL) will roll-off also (SPL and Roll-Off are explained in the next section)


For earphones that need to be used with mobile phones such as a Blackberry or iPod, a Click-Mic is a small device on the earphone cable that allows you to answer / end calls, the callers’ voices are then put through to the earphones, and the mic picks up your voice. For iPhones, the click-mic can also control your iPod; it will stop and resume tracks, skip, rewind, etc.
