Your Portable Audio Gear Guide

This page gives you a broad understanding of the various audio gear that we have and the functions and differences that go with it. We assume that you already have an idea about sound quality, design, durability and so on. However, for those who are unfamiliar, there are more to portable audio speakers than just simple distinctions between price and brand name. Thus, in the following table we have outlined the general specifications of the available headphones, earphones, loudspeakers and docking stations that we have available at Amplified Headphones Store.

We hope the brief explanations offered here, help you better understand and appreciate the sound reproduction capabilities of these sophisticated speaker equipments. Mobile audio gears have never been more elaborate than they are now. As you know, the advancements in digital audio technology with affordable and easy access to music data storage and online streaming music have subsequently created huge demands for portable personal audio listening gears. Our shop caters to this particular demand.

To kick things off, firstly, there are two main categories to portable audio listening equipment i.e. audio headgears and tabletop loudspeakers. These two categories are then divided into subparts that consist of in-ear monitors, closed and open back headphones, ear buds, circumaural/supra-aural cups, smartphone docks, PC/MP3 player speakers, wireless, wired, sports-ready ones, noise cancelling, noise isolating etc. We have explained all of these and more below.

Audio Speaker Terminologies




The main sound reproduction mechanism. It coverts electrical energy into sound waves that produce the audio output. In theory, the wider or bigger the driver the louder or better the sound.

Although we admit, this is not necessarily an accurate assumption. Other elements do play a part and oftentimes manufacturer’s label and description omit these points.

Frequency Response

It tells you how low and how high the speaker can reproduce sound. Once again reality reveals results differently.

Theoretically, a speaker rated as 20Hz – 25kHz +/- 3dB will play lower bass and higher treble sounds than a speaker that measures 40Hz – 20kHz +/- 3dB.

However in truth, that is not exact science. A lot of other factors come into play. Factors like space, driver size, audio quality, input power and so on, influence and effect frequency responses.

Therefore reading up audiophile reviews on your favourite headphone or ‘target buy’ is a wiser option. Better still, we recommend you go test the product for yourself whenever available.


Impedance is the resistance of the speaker to the electrical power input from an audio source – measured in ohms. The lower the ohms rate the louder the speakers will sound at a given volume from the audio source.

Hence some high-end headphones require an amplifier to help boost the audio source output power in order for you to enjoy the capacity of your heaphones that has high impedance count.

Max Input Power

Indicates the maximum power that your speakers can optimally handle from an audio source without deteriorating the audio quality.

Max Output Power

In reverse to input power, the maximum output power is the audio power that your speakers can produce optimally without causing distortion.


In common layman terms, it’s the measurement for how loud your speakers can go at a given volume level. So the higher the sensitivity the better the quality of audio.

Plug Type

Generally it is the industry standard 3.5 mm plug either chromed or gold plated. You can hook these smaller plugs to an 6.3mm adapter jack for an audio output source that has bigger headphone plug slot.

Adapter jacks are readily available at hardware or electrical goods stores.


How heavy your headphones weigh with or without the cables.


Mostly measured in meters for the length.


Full size headphones (cups cover entire ear)


On-ear pads (cups sit just on top of the ear)

Amplifier (amps)

A portable device that enhances your headphone’s sound reproduction capacity. Refer to the impedance specs of your headphone speakers; for example, speakers with 50 ohm impedance require more power from your audio source than speakers with 30 ohm impedance rate.

If you have high impedance headphones, an amplifier can help overcome any lack of power issues.


Headphones and Earphones

On Ear (Supraural)

Ear Pad Headphones These headphones are usually small pads that go over your ears, but don’t cover the entire ear. Since they don’t, expect small percentages of sound leaks; might annoy the person next to you if you are in a library, train or airplane. On the upside, they are the most comfortable for long usage and very nifty and portable.

Over Ear (Circumaural)

Full Size Headphone Full size headphones come with ear cups that cover your ears completely. Their large size makes them ideal for home use but it is not uncommon to use them on the go as well. Many models have foldable mechanism with convenient carry cases to allow easy portability.

Open Back

Open Back There are two types of over-the-head phones – open and closed back. The image on the left is an open back type where sound is audible both ways; inside and outside.

Although the outward decibel is not as high as the inward, people next to you can hear the audio played from your headphones. So you may want to select the right place where you want to put your open back cans on.

Open back headphones offer listeners an all round natural and rich sound. They are suitable for those who want to enjoy their audio with that realistic sound feel, and at the same time be aware of their surroundings.

However, the bass is normally less prominent compared to closed back headphones but this does not reduce the overall audio quality. It will still sound good. In fact a lot better if your open cans are the high-end kind.

Closed Back

closed back As the label suggests, closed back headphones are just that. Think of it as a ‘concert for one’ experience, though it is not as soundproofed per se.

On the other hand someone relatively close will not be able to hear the sound emitted from your headgear. 

Closed back headphones are the ideal choice for prolonged usage where privacy and quiet is sought. They don’t tire your hearing like in-ear plugs might do sometimes but they also do not offer complete sound isolation as in-ear plugs can.

Noise Cancellation

noise canceling Some headphone models come with an added feature called noise cancellation.

It is a switch set in your headphones that actively cancels out external noise. You need batteries to operate this particular feature.

Many users have indicated that this feature does not affect the overall sound quality and they are very effective in their purpose. However, we advise that you keep spare batteries handy though – to continue to enjoy the good audio quality.

Noise Isolation

noise isolation Noise isolation basically means that the listener would be the only one who will be able to listen to the audio coming out of the headphones.

Full sized headphones are designed for this in general.

Therefore, most headphones out there would have this feature.

Having said that, some models are better at it than the rest.

Ear Buds

ear buds The standard stock type that comes with your mp3 players and smartphones.These buds sit just outside your ear. They are prone to drop off and the performance is average at best.

Thus they are not very popular among audiophiles and you would not be able to find many high end types in market.

We recommend that you discard the ones that came with your mobile music device and get a better pair. Not only will you enjoy superior audio quality, you will also be able to prevent yourself from unnecessary ear discomfort.

In-Ear Plugs

In-Ear Plugs Now these are the true meaning of noise isolation. These plugs sit snugly in your ear canal and will drown out external noise. It will be just you and your music

Plugs are very popular because they are lightweight, small, extremely flexible and offer instant portability. They come in fashionable colors and styles too.

part from the sound isolation, you need to pay attention to the comfort factor too. With in-ear plugs, your ear drums are bombarded with direct audio decibels.

As such, if you have lesser quality plugs, this can be excruciating to your ears after a while. In that regard, it is wise to invest in a reputable brand that has perfected the comfort and output sound in this respect.

Secure Loops or Clip Ons 

loop or clip Secure loops and clip-on earphones are designed to give you a non-slip off function.

The difference lies not in the audio performance but rather their functionality and all popular headphone manufacturers have these models in their collection.

The ear plugs or pads are secured to the ears with either a loop or clip that runs behind your ear. These are good for gym or sports activity since many of them are washable and sweat proof.




Fender Newport These audio speakers offer quality Hi-Fi stereo sound output that you can use at home, at a house party, beach or anywhere else you desire to share your music.

They come with built-in amplifiers, rechargeable batteries and are portable. They produce amazing sound quality and not to mention a sense of style to its surroundings. Some models have wireless Bluetooth and WiFi streaming features.


TAGA Platinum One Passive speakers are non-powered. In otherwords they do not need power supply/battery to operate. They however, would need a external amplifier to drive them. There are various dimensions; from tall floor standing varient to bookshelf display sizes. Generally, they are 2-way speakers with a twitter and midrange dynamic drivers.
