Closer Examination

The case is instrumental to true wireless earphones, providing storage and charging capability. It may also be the first thing you take out of the packaging. It may look bulky, but while somewhat on the larger side of average, it is one of the lightest TWS cases I have used at just over 45 g in mass. Also note its translucent nature using a mixture of soft-touch ABS plastic and polycarbonate to where you can get a preview of the electronics inside. This is especially handy given the charging and battery status indicator LEDs on the front, which shine through the case. More notably, the case supports NFC connectivity with the tag clearly noted on the back where the Type-C plug is seen. This makes for easier Bluetooth pairing, at least with devices supporting it. Up top is a patterned take on the MOONDROP name, with the design matching that of the earphones, which is a neat touch.

The sticker on the bottom answers all my battery capacity questions while also clarifying why the case is slightly larger. It boasts a 700 mAh/2.59 Wh battery inside, which promises long battery life for the earphones in conjunction with the case. Knowing that the earphones themselves have a 50 mAh battery inside means that a perfect scenario would result in seven charge cycles out of the case. Of course, there are operational losses to account for, so MOONDROP rates six charge cycles out of the case. Unfortunately, there is no fast-charging support, so it will take 3.5–4 hours to charge the case fully. Open the case and you will notice that the three indicator LEDs correspond to the same seen below, with the earphones having their own LEDs for charging and Bluetooth pairing indication. The cradles are large enough to accommodate larger ear tips too, and magnetic pins hold both earphones in place during charging, which can take north of an hour if they are completely drained.


Fitting the protective case around the charging case is easy enough, but you have to push the lid in with more force than you might have originally anticipated. Once done, it will be a secure fit and allow the hinge on the back to open up flexibly without having the lid come loose. The practical nature of this add-on case is less thought out since it adds further bulk to an already large case. If thrown inside a purse, for example, it may not even fit in anymore. It's a trade off since it also covers the LEDs on the front, which you should account for if you are purchasing it to prevent scratches and dents to the charging case itself.


It's obvious from the get-go that MOONDROP fashioned the two earphones after IEMs, which shows with the more ergonomic layout for the shells. As with the case, a combination of soft-touch ABS plastic and polycarbonate is used to make for a translucent shell with an opaque and hard face plate that is customized based on the chosen color. Interestingly, the black version is more heavily adorned than the other two, and in different designs for the two face plates with a star and crescent moon bewitching you into liking these more. The recess in the middle is the region of interest for the touch sensor itself, although you will still just find yourself aiming for the middle once these are installed in your ears, of course.

A look from the side also confirms where the multi-color indicator LED is located, which lights up during pairing and charging. The included manual describes what the colors and flashing/solid states mean. Two vents are on the top and bottom, and another on the side is filtered for airflow, but also access to a microphone in each for communication. The underside has the corresponding contacts for the case, and there are no L/R markings here, which is a strange move for a product targeting the mainstream TWS market. These shipped without pre-installed ear tips, and we thus see the nozzle that is an extension off the shell itself. There is no retaining notch to hold the ear tips unfortunately, and the end is a thick 5.5 mm in diameter with a metal grill filter that prevents contaminants and ear wax from entering the acoustic chamber.


Installing different ear tips is quite simple owing to the nozzle geometry, although the thicker diameter means that thinner bore tips will struggle to fit over. Seen above are the four types of ear tips that come with the MOONDROP Sparks, in size M, with the foam tips only in this size to begin with. Note the different form factors, let alone the composition in terms of outer flange flexibility, which will affect the sound signature to an extent. I suggest trying all of them before honing in on the best balance of fit and sound.
