Echobox is a company based in US and went through a successful Indiegogo campaign in 2015. They started out with the Finder X1 which is an extremely durable titanium-housed earphone. It uses the German PEEK driver and there are interchangeable filters. In addition, Echobox has their own digital audio player (DAP) in the Explorer. Recently, they have released their entry level in-ear monitor, Traveler, as well as their flagship in the Nomad. In this review, I will be reviewing the Explorer. I would like to thank Echobox for this review unit. At the moment, you can purchase the Explorer from .

Sound Analysis


The Explorer has a smooth sub-bass reproduction and the rumble is moderate. The sub-bass is being extended well and the depth it reaches has a good magnitude. There is a nice mid-bass slam. The presentation is clean and there is good rendering of details. The nature is slower but the warm and smooth approach is relaxing to listen to. Bass texture is smooth with a moderate decay. Bass articulation is rather accurate.


The midrange on the Explorer takes on a full-bodied approach and there is a good quantity to its lower mids section. Male vocals are presented nicely without sounding hollow or dry. The upper mids are forward and female vocals are presented in a smooth yet intimate approach. There is a good control in the vocals reproduction. The midrange definition is great and it enhances the performance.


The treble has a rather good extension and there is no sibilance and harshness. Like the other frequency range, it operates in a smooth approach too. There is no grain in the treble and it is presented with finesse. Texture is smooth. There is a good amount of air at the top end that gives space to the overall sound. I find the air rendered to be excellent as it makes the sound very realistic and reduce congestion.


There is a natural expansion in the soundstage width and it gives a surround feel to it. Positioning of vocals and instruments is pretty precise. In addition, there is a good depth so you will not feel that it is close in.

Bass texture on the Explorer is slightly more smooth. The mid-bass operates in a laid-back approach with a moderate slam. The lower mids on the Explorer has more quantity and male vocals are better presented. The upper mids on the i5 is more forward and this helps to allow female vocals to be prominent.

On the other hand, DPX1-A is dry. For the upper mids, the Explorer has extra body to it and there is good definition. The DPX1-A is thin in its midrange. Explorer presents itself in a more organic manner. For the treble section, Explorer has a smooth approach while DPX1-A takes on a more analytical style. DPX1-A is prone to sibilance and harshness.

The bass note on the DX80 expresses itself with more agility. Decay on the DX80 is faster. The mid-bass on the Explorer has more quantity and its slam has more weight. The lower mids on the Explorer is presented with the extra body to prevent hollowness in male vocals. The upper mids on the DX80 has more forwardness and there is more energy from it. Female vocals benefit from it. Next, in the treble section, Explorer is more laid-back while DX80 operates in an exciting style. The extension on both is around the same.
