As wireless technology becomes better, Bluetooth earphones have become popular in the consumer market. KuaiFit aspires to make them even more accessible to more people through a cheaper, quality product, by selling the K Sport Wireless Earphones directly from its Kickstarter page
KuaiFit has an app by the same name which offers voice-guided personal training services in almost every type of exercise, from cardio to weight-lifting. A vast range of connectivity to third-party sensors is available, like heart rate sensors and GPS devices, which work well with guided coaching.
The app starts off with selecting a fitness level: beginner, intermediate and advanced. Thereafter, one has the ability to connect with real personal trainers via a subscription to its paid service. The subscription comes free for 6 months with the earphones, and R30 per month thereafter.
The box includes a manual, a USB to two USB Type B connectors, different sized soft plastic eartips and the two earphone units. Each earphone is wireless and connects to the other independently of wires. This puts the K Sport Wireless in the realm of the Apple Earpods in terms of connection style.
The earphones are just over 2cm wide and 2cm high. The set is black with a light blue KuaiFit logo on the earphone’s button.
The button functions as an on/off switch when long-pressed and a play/pause button when quick-pressed. The dual-button set-up is convenient in everyday use, allowing for playback control depending on which hand is free. Two connectivity modes are available, single earphone mode or dual earphone mode. The dual earphone mode intelligently connects the second earphone and syncs stereo audio a few seconds after powering on.
In terms of connectivity, the earphones are Bluetooth 4.1 with a massive 10-meter range, provided there are no obstacles between the device and the earphones. While it’s not Bluetooth 5, it still falls into the Bluetooth Low Energy connection category, meaning that the smartphone’s battery won’t be drastically affected by a consistent connection to the earphones. The batteries within the earphones aren’t specifically listed but last anywhere between 3 and 6 hours, depending on the mode.
Audio quality is surprisingly good for earphones at this price point. The headset style is restricted to in-ear due to its small design and probable usage in movement-intensive activities. As a result, one has to be very careful how one puts these earphones, in because bass has the potential of getting reduced from an incorrect in-ear placement. In-ear earphones are usually notorious for ear discomfort and suction pain after extended usage. These earphones are one of the very few in this price range that are comfortable and don’t cause discomfort. The good quality of the soft plastic ear tip is definitely a factor in the high level of comfort of the in-ear earphone experience.
Overall, the K Sport Wireless earphones are great considering the sound quality and the low price: US$30 on Kickstarter.
