Reviving an old spirit, the Soundcore Spirit Dot 2 restores the former glory of the Spirit Pro with a completely wirelesses solution, which has a unique design that brings a breath of fresh air to an otherwise stagnant "market pool" of true wireless earbuds!
The Spirit Dot 2 charging case lid slides outward horizontally and smoothly via a metal slide hinge that retracts the lid all the way out so, the lid doesn't get in the way of taking the earbuds out of the charging case. The recessed docking area and the white enamel color makes the earbuds look like they're having a dip inside a bathtub. The sliding lid mechanism is the same as the Liberty 3 Pro There are three battery status leds on the front of the charging case and, a USB-C charging port on the rear with a rubber flap to protect the charging port from moisture, dirt and pocket lint/gnurr which easily finds its way into the charging port of devices, especially when keeping them inside trouser pockets.
It's surprising that so many charging cases of true wireless earbuds don't integrate a rubber plug to protect the charging port. That said, the Spirit Dot 2 charging case doesn't have an IP rating; hence the charging case is not water resistant, which it couldn't be anyways due to the sliding lid. While the lid closes snugly, the gap around the lid is not sealed tight; hence water could easily get in. That said, the charging case lid does have a beveled edge, which should help divert water away from water splashes on top.
The Spirit Dot 2 earbuds do have an IP rating (IPX7 waterproof) so, you can technically submerge the Spirit Dot 2 under a meter (3.3 feet) of water for approximately 30 minutes. This said, the Spirit Dot 2 earbuds are not safe for swimming, which requires an iPX8 rating.
While not suitable for swimming, the Soundcore Spirit Dot 2 are more than suitable for exercise. In fact, the earbuds won't fall out or slip out when sweating or running in the raining, thanks to the half-moon design of the earfins, which create an anchoring point on the inner side of the concha of the ear.
The ear-fins are made of soft silicone so, they don't rub against the skin nor should they cause any skin reactions because silicone is hypoallergenic. The ear-fins are easy to remove and attach. They stay securely in place without sliding around, thanks to a small notch.
The Spirit Dot 2 charging case have a dark space grey style with a smooth powdery-like finish without any markings on the outershell other than a chromium etching of the Soundcore logo on top of the lid, which also features a small raised triangle that provide grip when sliding the lid open.
The Spirit Dot 2 integrates a 340 mAh rechargeable battery that takes 2 hours to fully charge and delivers 16 hours of extra charge. The Spirit Dot 2 earbuds touch control panels have nice responsiveness and integrate a similar looking chromium logo etching found on the charging case. You can play/pause music, answer/end calls and activate the voice assistant but, there is no volume support and, you cannot skip tracks backwards (only forwards), which is rather odd.
Given that the Spirit Dot 2 are marketed to fitness enthusiasts, the lack of volume and skip backwards  may or may not be a deal breaker, depending on how accessible their phone is when exercising. The 8mm drivers inside the Spirit Dot 2 drivers are pretty sensitive though, and capable of outputting 97db, which is a lot of volume power perfect for drowning out the clanking of weights. If volume/skip functions are still a requirement for your needs though, you should look to the Liberty Air true wireless earbuds.
The Spirit Dot 2 nozzles have brass metal tips with quirky swirly perforations much larger than regular mesh tips. The large perforations along with the tiny vent holes likely contribute to the bass heavy sound signature. There is no app support though; hence you won't be able to tweak the sound like you can with the Liberty Pro 2 true wireless earbuds.
There is one microphone per earbud, which work well, although they don't integrate any noise background reduction like the Spirit X2 and Liberty Pro 2 do; hence noisy environments will compete with your voice during calls. If you require active noise cancellation, check out the Soundcore Life 2.
The Spirit Dot 2 earbuds take 90 minutes to charge and support 10-minute quick charge, which provides 1 hour's worth of playtime. From a full charge, the earbuds can deliver up to 6 hours of playtime when listening to audio at 50% volume and via SBC codec.
The Spirit Dot 2 Bluetooth 5.0 also support AAC but does not support aptX, which typically means sound delay when watching content via the YouTube app on an Android device. That is not the case with the Spirit Dot 2 though. The reason being, it's that Spirit Dot 2's Bluetooth 5.0 chip supports Airoha's new TWS MCSync technology, which lower video/audio latency and also eliminates re-connection delay, which creates a better experience when switching from mono to stereo listening. MCSync doesn't seem to improve latency with iOS devices though. This is likely due to Apple's stringent walled garden ecosystem.
The Spirit Dot 2 earbuds weigh 5 grams each, while the charging case weighs 50 grams and measures 8cm long, 4.5cm wide and 3cm high. Some gaming can be done with the Spirit Dot 2, although MCSync doesn't beat aptX LL (low latency).
Spirit Dot 2's Bluetooth 5.0 has a stable wireless signal within a 10 meter range in direct line of sight but, it does not support multi-point pairing; hence you cannot connect the Spirit Dot 2 earbuds to multiple devices at the same time.  Unless of course, you independently connect the earbuds to different devices, which you can do with the Spirit Dot 2.
Bluetooth pairing gets automatically activated when removing the earbuds from the charging case. If you don't connect them, the will automatically go into standby mode after 2 minutes. Once connected, the status leds will blink every 3 seconds while using them.
Accessories included are different size eartips and ear-fins, as well as an unbranded USB-A to USB-C charging cable that measures 40cm long.
