You need to look for the following factors when choosing a mic-containing earbud:
- Pitch Range
Also known as frequency response among audiophiles, an earbud’s pitch range determines its resistance against noise distortion. Put simply, the greater the pitch range, the less will be noise distortion.
As a result, if you choose an earbud with considerable pitch range, it would respond equally well to both low and high-frequency sounds. That means you’d have more bass thump, concise treble, and audible low notes.
- Noise Isolation
For those of you who’ll be using their earbuds while working out or commuting, make sure they have the noise isolation feature. It is nothing technical, instead, earbuds simply isolate outside noise by putting a seal against your ear.
While headphones do that by covering your whole ear, earbuds only cover your ear’s opening. That, in turn, keeps the outside noise at bay to allow you to focus on the music at hand.
- Noise Cancellation
Forbes tells us that noise isolation and noise cancellation aren’t the same things. For, while the former blocks out all outside noise, noise cancellation allows lets some of it in.
That feature is important if you’re running or walking in traffic and can ill-afford to be oblivious to your surroundings. Also, you can control the level of noise cancellation, whereas noise isolation is absolute.
- Comfort and Fit
Comfort and Fit are two different things when we talk about earbuds with mics. An earbud might fit perfectly but it could still be not comfortable. That means that despite the fact that it could provide excellent sound quality, you’d have no choice but to bin it.
Therefore, while choosing an earbud, make sure it is both comfortable and fits perfectly into your ear canal.
- Built-in Mic
There are three types of built-in mics in earbuds: unidirectional, bidirectional, and omnidirectional. These types differ on how each of them picks-up sound. For, while the unidirectional mics pick up sound from the front direction, bi-directional ones do the same for both front and rear.
Luckily, most earbuds these days come with omnidirectional mics, such as those which pick up sound from all directions. It means you won’t have to bring the mic close to your mouth before speaking.
