Today we bring you the analysis of the Ozone Dual FX, the latest headphones that Ozone has launched to the market. These in-ear headphones are designed to be light and comfortable, while offering a lot of functionality and excellent sound quality despite their compact design.
The Ozone Dual FX are in-ear headphones with a 3.5 mm jack connector. The speaker size is 6 mm, but each headset has two speakers, so we have the equivalent of having a 12 mm one. We also have an impedance of 16 ohms, a sensitivity of 107 ± 3 dB, and a frequency between 10 and 40,000 Hz.
This last range is greater than that heard by the human ear, but since there is also part of the sound that comes through bone conduction, some headphones usually include higher frequencies. In addition, it is the minimum spectrum required by the Japanese Audio Society for headphones to receive the Hi-Res certificate, which these headphones have.
As for the rest of the physical characteristics of the headphones, we found a weight of 15.8 grams, a cable length of 1.2 meters, controller for calls, volume and music, as well as several pads whose sizes we will see in the unboxing.
Ozone Dual FX Review – Unboxing and external analysis
The headphone box is quite compact, it comes protected with a plastic. If we remove the plastic, we can slide the protective cardboard to get the headphones.
When opening the box where everything is found, we find the following content:
Hard case for headphones
S, M and L size pads (M are pre-installed)
PC adapter to use headphones and microphone while playing
The carrying case is very compact and rigid, thanks to which we will always keep our headphones safe, and that it has a soft zipper that is a delight to use. As for silicone pads, their exchange is quite simple by pressing at the right point.
The jack connector has a cable that comes out at an angle of 90º, which makes it ideal for use while playing or playing music. In addition, the cable does not have any slack inside the connector, which guarantees that there will not be broken as it happens with other headphones on the market.
Ozone Dual FX Review – Excellent in-ear headphones
The use of the two speakers per headset is undoubtedly very successful. My daily drivers are JVC HA-FX1X, which are in a similar price range, and the difference in sound quality is abysmal. The first thing that stands out in the Dual FX is the power and body that the bass have, almost that it can even make you believe at times that you are wearing on-ear headphones. The media and the highs are fulfilled, having a round sound for headphones that are worth only 25 euros.
Silicone rubber bands are very comfortable and make the headphones fit well inside the ear. In my case I usually wear the smallest size because I have a small ear canal, and this type of headphones often comes out of my ear. With the Dual FX I have not had any exit problem, staying in place even with movement walking down the street. In addition, the insulation is excellent and the sounds of the environment are barely heard.
The inclusion of the cable to use it on PC is a success, since we can use them as gaming headphones wherever we want thanks to have a microphone, so they are ideal for use in a laptop for example. The 90º exit of the cable is very comfortable in laptops and with the mobile if we are using it in front, although it is not so comfortable if we carry the mobile in the pocket.
Going to the buttons, we found a volume slider and a multifunction button. The slider is soft and stays in position, but this can be a point that hundreds of hours of use should show if they last or if they have wear problems. At the moment everything looks like it is quite durable. If we leave it in the highest position, the volume will be at maximum, while at the lowest the sound will be muted. This will allow us to adjust the volume quickly if we are playing on a laptop and we have to use FN commands to adjust it.
As for the microphone, the sound is very clear and the voice is perfectly heard, even when we have them hanging and we are not speaking directly to the microphone as we do with gaming headphones, since the microphone is omnidirectional. Of course, we will have to slightly increase the gain so that we can hear the voice with a power similar to a headset.
With regard to the button above the slider, it will allow us to perform many functions. In music playback mode, a single touch will pause or continue music playback. If we press it twice, it will go to the next song. If we press it three times, it will go to the previous song. In the case of receiving a call, we can pick up and hang up by pressing the button once, as well as we can reject the call if we press the button. Between the slider and the button we find the microphone hole.
Finally, as a more mundane aspect, the cable has an elliptical design, so that it does not tangle and we can unwind them easily after having them stored.
