Closer Examination

The case is instrumental to true wireless earphones, providing storage and charging capability. What Tronsmart includes with the Apollo Air+ is more typical in design and composition for budget-friendly TWS earbuds, adopting a plastic body in a matte black finish that is fairly fingerprint and scratch resistant. The Tronsmart name is etched into the top, and a single LED outside is all you get for battery and charging status. It flashes blue thrice for a case battery of 11–100% when the case is opened or red if at 1–10%. A solid red light greets you when charging, which then turns off when the case is fully charged. As such, it is not very handy in use—it would have been nice to see it perhaps flash twice or even once for different battery states. The Type-C port is on the back, where we also see the stealth hinge mechanism. Opening the case is simple enough courtesy the cutout in the middle, which is just large enough to be practical but not obnoxious, nor does it allow dust inside.

There are the expected L/R markings with deep channels to hold the earbuds, which are in turn held and also charged via magnetic connectors. The largest of the included ear tips fit in quite easily with the earbuds, so there is room for aftermarket tips. The case has certification and more technical information on the inside of the lid, and we find out it charges on USB 2.0 500 mA over the 5 VDC line limit. It also supports wireless charging, which is nice to see even if a compatible Qi charger is not included. The case battery itself is rated for 1.11 Wh, which on the usual 3.7 V operating voltage translates to a measly 300 mAh battery inside. No wonder rated battery life is not much, even if Tronsmart does not provide more battery specifications about the case and individual earbuds. There is a similar single LED to indicate charging of the buds themselves, and charging them takes the same 2–2.5 hours as for the case itself.


The Tronsmart Apollo Air+ earbuds have the sound tubes enter the ear canal, so they are not true earbuds by definition. It's the external design that makes it easier to call them that for the general public to relate to, and I will do so as well. The longer stem design allows for more room to fit components there without restricting the acoustic chamber and driver system, which in this case ends up being a thin stem and relatively small head. It makes for lightweight ear buds for the size, which have a black plastic finish. The external surface area of the heads has the Tronsmart logo in white under an acrylic layer; it is smooth to the touch, and the black makes fingerprints harder to spot.

The part entering your ears is angled inward, conducive to going into the ear canal on either side. There are L/R markings above the magnetic pins to indicate the left and right channels, and a matte black plastic nozzle jutting out the sides is filtered to prevent contaminants from entering the insides. A retaining notch on the nozzle helps with ear-tip installation, making it harder for the silicone tips to come off once fully pressed in. By default, a set of medium-sized tips come pre-installed, but you may want to try the other sizes or even your own spare tips to make sure you get the best fit.
