Main Specifications and Analysis of its Features


Lightweight design and Firm built

We think that the primary and one of the most important features of this on ear headphones is its weight and it is pretty lightweight so that carrying it around does not add a bulk to your bag or suitcase.

As well as the 209 gram headphones can be easily listened to for hours or maybe just placed around your neck without feeling strained as the inner arc of the headband of the JBL C300SI is coated by a soft material which makes the device rest easily on top of the head unlike most of the dynamic headphones in this range which have bare plastic body which is quite uncomfortable.

The headphones are built out of 80% plastic but it does not mean that they feel cheap as they give a good look and and the device seems sturdy with no tweaking sound and earcups are coated with a soft rexin like material which is very comfortable to the ear and the earcups are self adjusting as well so they can align themselves easily according to your ears and the device can be adjusted to with the help of the levers to change the fit according to your head size.

As we all know that Gold is a good conductor of electricity hence the headphones have 3.5 mm jack which are gold plated to ensure good conduction.

Talking about the cable on the wired headphone which is not tangle free cable but nevertheless you don’t have to worry about them snapping as they are coated with a good quality plastic and the earcups can be removed to clean them up as well as change them if they have deteriorated.

Good Sound Reproduction with Decent Bass quality

Alright so the sound performance of the On ear headphone is decent and can be used on a regular basis either when going outside or maybe for a jog as the music heard is loud but tends to get a bit creaky on the higher upper part of the decibels.

The earcups being self adjusting try their best to isolate the noise from the outside and do their job well but don’t entirely cancel out the sound but we cant criticize this product too much on this review as JBL has managed to provide a lot in such a low price point.

The voices heard when watching a movie is clear and crisp on the JBL C300SI as well as the bass is decent but not very deep or low,and the intermixing of the bass with the treble might need a bit of equalization for better output on the although the depth of the audio is much better when compared to other devices of similar features maybe because of the HarmanAudio standards.

The magnetic drivers on the audio device provide a frequency range of 20 HZ – 20 kHz that allows the device to generate good volume and also nice sound quality.

Wrapping up Statements

The JBL C300SI is surely of better than average built quality and the comfort impressed us moreover the sound and the bass is enough for a good immersive experience for a normal average consumer apart from the bass heads who would require a bit more although these headphones can be tweaked on the equalizer to manage to produce optimum treble and bass according to ones choice.

Hence Wrapping up this review we can say that the JBL C300SI is a great product and can be used for a long number of hours to listen to music or maybe any other type of audio like podcasts etc,hence the company has surely done a good job to deliver a good headphone at such a Budget range.
