Design And Build Quality

The design and build quality of the Monster XKT12 earphones showcase a sleek and practical approach. Both the case and earbuds are crafted from durable plastic materials, ensuring a lightweight yet sturdy construction. The case features an open-style design with no lid, providing easy access to the earbuds. Its rectangular shape is accented with a stylish transparent top part, complementing the solid color base. With color options such as black, beige, white, purple, and pink, users can choose a design that suits their personal style. It has another transparent part at the bottom that shows the internals of the device and also has LED lights that light up when charging, additionally, it has a lanyard hole, allowing you to attach a strap and carry the case with ease. The inclusion of a strap in the box is a thoughtful gesture, encouraging the utilization of this practical feature.

The earbuds themselves boast a design reminiscent of the AirPods 3, fitting comfortably in the ears. The sealed ear cups offer passive noise-canceling capabilities, enhancing the overall audio experience. The earbuds securely slide into the case, thanks to a magnetic mechanism that holds them in place for charging, ensuring convenience and protection.

Furthermore, the XKT12 earphones boast a certain level of water resistance, although the exact rating remains unspecified. Assuming an IPX4 rating, the earphones are protected against water splashes and light droplets, making them suitable for workouts and rainy conditions. However, it is essential to exercise caution and avoid submerging them in water, as they are not designed for complete water immersion, which may lead to irreversible damage. Overall, the design and build quality of the Monster XKT12 earphones offer a blend of style, practicality, and protection for a satisfying user experience.

Monster XKT12 – Audio Quality

The Monster XKT12 earphones boast a 13 mm driver, covering a frequency range of 20Hz to 20kHz, ensuring a broad and immersive audio experience. The sealed ear cups provide sound isolation, effectively reducing external noise without compromising battery life or sound quality. This feature enhances the overall audio performance, allowing users to enjoy their favorite content without interruptions from the surrounding environment.

The XKT12 earphones support both AAC and SBC codecs, contributing to their high-fidelity audio quality. SBC codec prioritizes power efficiency while maintaining satisfactory sound quality. On the other hand, AAC offers superior audio performance, particularly for iOS devices, although it may lead to slightly shorter battery life. Users can enjoy noise reduction benefits and experience rich and clear sound during both single and binaural use independently, without worrying about master-slave switch constraints. With Bluetooth 5.3 technology facilitating seamless sound transmission, the Monster XKT12 earphones deliver an exceptional audio experience for music enthusiasts and on-the-go listeners alike

Microphone Quality & Bluetooth Calling

The Monster XKT12 earphones feature microphones on both earpieces, contributing to an improved calling experience. Combined with Bluetooth 5.3 calling support, users can enjoy seamless connectivity and clear sound during calls, particularly in quieter environments. The earphones also employ ENC (Environmental Noise Cancellation) algorithms to minimize background noise and enhance voice clarity. While this technology is effective in reducing noise in certain situations, in more complex and noisy environments, call quality may be affected, leading to occasional muffled voices and limitations in noisy settings.

The XKT12 earphones provide a convenient calling experience with their integrated microphones and Bluetooth calling feature. The ENC (Environmental Noise Cancellation) algorithms contribute to improved voice clarity in relatively quiet surroundings, allowing users to have clear conversations. However, it is essential to note that in noisier environments, the performance of noise reduction may vary, and call quality may be impacted. Despite these limitations, the earphones offer practical calling capabilities, catering to users’ communication needs during daily use.

Low Latency & gaming mode

The Monster XKT12 earphones come equipped with a gaming mode that can be activated using the touch control feature. This gaming mode is designed to reduce latency, providing users with a better gaming experience while playing mobile games such as PUBG Mobile and COD. By minimizing the delay between audio and visual cues, the gaming mode enhances the responsiveness of the earphones, giving users a competitive edge in gaming.

It’s important to note that the gaming mode prioritizes low latency over sound quality. As a result, users may notice a slight reduction in sound quality while using this mode. However, this trade-off is intentional to ensure a seamless and immersive gaming experience without any lag or delay.

For optimal performance, users are advised to activate the gaming mode only when gaming, as it may not provide the same audio quality for music or other forms of media playback. With the gaming mode, the Monster XKT12 earphones cater to gamers and mobile gaming enthusiasts, delivering a more enjoyable and responsive gaming experience on the go.

Monster XKT12 Battery Life and Usage

The XKT12 earphones come with a 300mAh C Type-C charging box, providing a promising battery life of up to 20 hours. The charging box itself can be fully charged in around 1.5 hours. Each earpiece has a battery capacity of 33mAh and offers up to 5 hours of active use. The earphones can be fully charged in approximately 1.5 hours as well.

With the generous battery capacity of the charging box, you can enjoy extended usage without worrying about running out of power. The convenience of fast charging ensures that you can quickly recharge the earphones and get back to using them in no time. The XKT12 earphones are designed to keep you connected and entertained throughout your day with their reliable battery performance.

Final Verdict

The Monster XKT12 earphones deliver an impressive package with their Bluetooth 5.3 technology, providing a stable and reliable wireless connection, and supporting AAC and SBC codecs for versatile audio performance. The design and build quality showcase a sleek and practical approach, with a variety of color choices to match different preferences.
