ACEFAST T8 Earbuds Review: Stand Out with Their Eye-Catching Design, Audio, and Endurance

ACEFAST T8 Earbuds Review



The smartphone industry has been witnessing significant changes in recent years, with a shift towards wireless technology. One of the most notable changes has been the transition from 3.5mm wired headsets to wireless ones. This change was driven by the increasing number of smartphone manufacturers who started abandoning the traditional earphone jack on their devices and stopped providing wired earphones with the phone. Instead, they focused on creating a market for complete wireless solutions.

As a result, many brands started to launch wireless earphones, and some even stopped the production of wired headphones. This shift was driven by the changing market demand, with consumers increasingly preferring the convenience and flexibility of wireless headphones.

With the rise in demand for wireless headphones, many new brands also entered the market, one of which is ACEFAST. The company’s mission is to continuously pursue high-quality and practical products that are full of technological charm, catering to the needs of consumers worldwide, through an excellent supply chain.

ACEFAST recognizes the importance of providing high-quality products that meet the demands of consumers. One of its products, the ACEFAST Crystal (2) Earbuds T8, is a wireless headset that promises high-quality sound and a comfortable listening experience. In this review, we will take a closer look at what the ACEFAST Crystal (2) Earbuds T8 offers and how it performs.


Its bold and stylish design, with transparent earbuds and a charging case with breathing lights and LEDs, attracts attention immediately. The Acefast T8 is available in six eye-catching colorways, including lotus pink, alfalfa purple, mint green, ice blue, bright black, and white moon.

The T8 boasts impressive features such as 30 hours of battery life, IPX4 splash resistance, Bluetooth 5.3, 10mm drivers, and 6mm tweeters. In addition, it comes with a variety of in-box accessories. Let’s unbox the ACEFAST T8 and put it to the test to see if it lives up to its promises.


The unboxing experience of the ACEFAST Crystal (2) Earbuds T8 is exciting, with the package including the T8 wireless headset, a matching silicone gel case, a lanyard with the same silicone gel, three extra ear caps, a USB Type-C cable for charging, and a multilingual user manual.

The inclusion of the silicone gel case, lanyard, and extra ear caps add an extra layer of protection and comfort to the T8, while the USB Type-C cable ensures easy and compatible charging. The unboxing experience is well thought out and satisfying, making it all the more enjoyable to experience the sound quality of the T8.


ACEFAST Crystal (2) Earbuds T8 is an innovative addition to the market of earbuds. The unique feature of the earbuds is the transparent housing design that exposes the motherboard and internal parts of the headset in detail. This not only adds to the aesthetic appeal of the earbuds but also allows the user to have a better understanding of the technology that powers them.

The charging box of the earbuds features a segmented LED digital display that shows the remaining battery power in the charging case and each earbud. The display is visible from any angle and provides the user with real-time information on the battery status of their earbuds.

The charging box also features an atmosphere-breathing light that glows for a few seconds when the user removes or puts back the earbuds, and when the charger is connected. At the same, it also shows battery status, which is very convenient. This adds an extra technological effect to the headset and makes the user feel as if they are handling a futuristic device.

The earbuds are designed to magnetically attach to the charging case, protecting from unintentional falls. In tests conducted by us, the earbuds did not fall out of the charging case even when subjected to sudden jolts.

The fitting of the earbuds in-ear is comfortable, thanks to the adjustable ear caps. The user can adjust the ear caps according to the shape of their ear, ensuring a secure and comfortable fit. Even after wearing the earbuds for two hours while watching a movie, I did not experience any stress on my ear. This is a testament to the ergonomic design of the earbuds.

The weight of a single earbud is 5.5 grams, which is lightweight enough to ensure comfort during prolonged use. However, it is not the lightest earbud available in the market. The charging case weighs 47 grams, which is lightweight and easy to carry in a pocket or a bag.

The charging case does not have any buttons. Instead, ACEFAST has given all the control to the earbuds via an upper interactive touch panel. This is a great feature as it eliminates the need for the user to carry the charging case together or use their phone to control the earbuds.


The ACEFAST T8 true wireless earbuds are designed to provide high-quality sound and reliable connectivity to their users. These earbuds come with a range of features that make them an attractive choice. However, there are also some drawbacks to consider when evaluating these earbuds.

One of the key advantages of the ACEFAST T8 earbuds is their 10mm aluminum-magnesium alloy driver and 6mm titanium dome tweeters. This driver and tweeter combination delivers a detailed, clear sound with excellent separation and clarity.

The Laser Direct Structuring (LDS) antenna design used in the ACEFAST T8 earbuds is another standout feature. This design provides a stable signal and helps to reduce electronic interference during radio transmissions. The antenna is placed on a plastic strip across the earbud stem, which helps to improve signal strength and reliability.

The latest Bluetooth 5.3 connectivity is another feature that makes the ACEFAST T8 earbuds an attractive choice. This enables faster data transfer speeds and more reliable connectivity. The earbuds also use the Bestechnic BES2600IHC dual-core processor, which enables Enhanced Data Rate (EDR) transmission for even faster data transfer speeds and more stable connections when streaming music or making calls.

The Environmental Noise Cancellation (ENC) technology featured in the ACEFAST T8 earbuds helps to reduce background noise during phone calls, making it easier to hear the person on the other end of the line. While it is not perfect, it does a good job of reducing ambient noise and improving call quality.

However, there are some drawbacks to consider when evaluating the ACEFAST T8 earbuds. They only support SBC and AAC audio decoding protocols and do not support Hi-Res Audio. The earbuds do not feature Active Noise Cancelation (ANC) technology, which means that they do not block out external noise as effectively as earbuds that do feature ANC. Additionally, the earbuds do not support the multi-point pairing.

Another drawback is that there is no companion app available for the ACEFAST T8 earbuds. This means that users cannot customize the sound profile or access additional features through an app. Finally, the earbuds do not feature wear detection technology, which means that they do not automatically pause playback when users remove them from their ears.

Touch Control

The ACEFAST Crystal (2) Earbuds T8 offers touch control options on the earbuds for easy and convenient use. By mastering these touch controls, I’m able to quickly answer or end calls with a simple double tap, as well as play and pause music. The earbuds also allow for easy navigation between songs, with three taps on the touch area of the right earbud to go to the next song, and three taps on the touch area of the left earbud to go to the previous song.

In addition to music and call controls, the touch area of the earbuds allows for other useful features such as adjusting the volume with taps on the right and left earbuds, rejecting calls with a 2-second press, and waking up the voice assistant with a 2-second touch on the left earbud. The earbuds also have a game mode that can be activated by tapping the touch area of the right earphone for 2 seconds.

To restore factory settings, users can simply touch and hold both the left and right earphone touch areas for 5 seconds at the same time. Overall, the touch controls on the ACEFAST Crystal (2) Earbuds T8 provide a convenient experience, but there is no remapping option.

Audio Quality

The ACEFAST T8 earbuds are packed with top-notch hardware to provide exceptional sound quality. When we played an action movie audio on these earbuds, we were amazed by the noticeable and loud bass effect. The audio profile is flat, but the built-in Dolby Atmos system tuning on my phone significantly improved the output. We also found that the music player’s equalizer worked fine, but an official solution for perfect tuning would be a welcome addition.

The overall audio output of the ACEFAST T8 earbuds is admirably loud and well-balanced. The vocals also sound good and clear, and we did not notice any significant latency while playing music or watching movies. This is a great bonus as it enhances the overall user experience. In terms of calling, our colleague on the other end reported a loud and clear voice, and we also experienced the same. However, at some point, our colleague noticed a faint voice, which is something to keep in mind. Overall, the connectivity of these earbuds outperforms without any connection loss.

Battery life

According to the official data, ACEFAST Crystal (2) Earbuds T8 comes with a 45mAh battery on each earbud that provides up to 7 hours of music playback and 4 hours of calling, while the charging case has a 480mAh battery capacity that offers up to 30 hours of playback. Additionally, the earbuds take only 1 hour to fully charge, while the charging case takes 1.5 hours.

Our testing of the ACEFAST T8 earbuds showed that they surpassed their official battery life claims. During continuous music playback at 100% volume, the earbuds lasted for an impressive 6 hours and 40 minutes, while during continuous calling, they lasted for 4 hours and 15 minutes. This exceptional battery performance makes the ACEFAST T8 earbuds a great option for anyone who wants to enjoy their music or make calls without worrying about running out of battery.

It’s important to note that the ACEFAST T8 earbuds do not support wireless charging. However, with their excellent battery life, quick charging times, and reliable performance, the ACEFAST T8 earbuds are worth it.


Overall, the ACEFAST Crystal (2) Earbuds T8 offer an impressive package of features for their price. With their eye-catching transparent design, breathing lights, and accessories, they are sure to stand out from other wireless earbuds on the market. The T8s also deliver above-average sound quality for music, movies, and calling, and boast an IPX4 splash-resistant rating, Bluetooth 5.3, and decent battery life.

While some audiophiles might lament the absence of ANC, Hi-Res Audio, and a companion app, the T8s are a solid option for those seeking a truly wireless experience without breaking the bank. The current 69.99 USD price with a 30% discount on the $99.99 original price also makes them an even more attractive choice.

Overall, the ACEFAST Crystal (2) Earbuds T8 represent a good value for the features they offer, especially for those who prioritize style and convenience in their wireless earbuds.
