Published on May 8, 2023, 6:18 p.m.
The ADV. 500 True Wireless Earbuds from Advanced Sound Group are an impressively compact and affordable pair of wireless earbuds. Despite their tiny size, these earbuds deliver surprisingly loud and powerful sound with deep bass. They utilize the latest Bluetooth 5.2 technology for an expanded wireless range up to 40ft and instant pairing. With a lightweight and ergonomic design, touch controls, and built-in mic, the ADV. 500 earbuds are a great everyday carry option.
- World’s smallest true wireless earbuds
- Bluetooth 5.2 connectivity
- 6mm dynamic drivers for powerful sound with deep bass
- Ergonomic design for comfort and secure fit
- Touch controls for playback and call control
- Built-in mic for calls
- Compact charging case for portability
One of the most notable features of the ADV. 500 earbuds is their incredibly small size. The charging case is barely larger than a quarter, making it the world’s smallest true wireless charging case. The earbuds themselves are tiny and lightweight, with a rounded design that fits comfortably and securely in the ear.
The minimalist aesthetics and variety of color options (black, pink, white, lavender) give them an elegant and modern look. The included silicone ear tips come in multiple sizes for a customized fit. A built-in wrist strap on the case adds convenience. Overall, the thoughtful design elements make these earbuds an excellent choice for active use and portability.
Despite their small footprint, the ADV. 500 earbuds are packed with useful features. Bluetooth 5.2 enables quick pairing and a stable wireless connection up to 40ft from your device. The 6mm dynamic drivers deliver surprisingly powerful and balanced sound with emphasized bass.
Touch controls on each earbud allow for convenient access to playback, volume, calls, and voice assistants. The built-in microphone enables clear phone calls. Fast charging provides up to 5 hours of playtime, while the compact case extends it to 25 hours total. The IPX4 water resistance rating means they can withstand sweat and light rain.
With custom-tuned 6mm drivers, the ADV. 500 earbuds put out impressive audio with strong bass and clarity across the frequency range. The sound profile leans towards a lively, V-shaped signature that enhances bass and treble. This makes them especially suitable for pop, hip hop, EDM, and other beat-driven genres.
While audiophiles may want more refinement, the exciting sound is fantastic for everyday listening and exceeds expectations for the price and size. Volume levels go high enough for noisy environments.
Comfort & Fit
Despite having one of the smallest form factors on the market, the ADV. 500 earbuds maintain a comfortable and secure fit. The angled nozzles and variety of eartip sizes allow you to achieve a customized, noise-isolating seal without pressure. The rounded edges and featherlight 4.4g weight means you barely feel them in your ears. This makes them suitable for extended wear.
Battery life is decent but not exceptional. You get around 5 hours of continuous playback on a full charge, which is good for true wireless earbuds. The pocket-sized charging case provides an additional 4 full charges, delivering up to 25 hours total. Charging the earbuds for just 10 minutes provides about 1 hour of listening time. Quick charging via USB-C means you can easily top up the case during the day.
The ADV. 500 earbuds are ideal for those looking for a compact and portable pair of true wireless earbuds. Their tiny size makes them great for activities like working out or commuting where you want earbuds that fit securely and don’t weigh you down. The sound quality makes them suitable for listening to music, podcasts, audiobooks, and more. They also work well for taking calls with their built-in microphone.
