The SoundCore Liberty 4 is a standout product in the field of true wireless earphones designed by Anker. This dual-dynamic driver earpiece brings an unbeatable balance of price and performance, competently delivering high-grade noise cancellation for a very reasonable Tk. 11,990 in Bangladesh, officially.
The stem-style earphones come in a glossy black finish accented with gold, both chic and compact, housing an internal combination of 9.2mm and 6.0mm dynamic drivers. This allows the Liberty 4 to deliver an impressive frequency range from 20Hz to 40KHz with an impedance of 16 ohms.
Functioning on Bluetooth 5.3 compatibility, the earphones support AAC, LDAC, and SBC codecs, but do not support AptX. The inclusion of LDAC support is substantial, permitting Android users’ high-bitrate streaming to fully employ the dynamic drivers’ capacities.
Control of the earbuds mirrors AirPod functionality, with stem pressing for various commands like playback control, switching between Transparency and active noise cancellation modes, and handling calls. Additionally, users can navigate tracks and customize controls including volume and voice assistant via the app.
The earbuds are designed with an IPX4 rating, meaning they can withstand light splashes from any direction. However, submersion or direct water rinsing should be avoided, and the earpieces should be dried thoroughly before docking as the rating doesn’t extend to the charging case.
The accompanying charging case brings a touch of elegance. Its black design features a sliding lid to access the earbuds and includes glowing LEDs that light up the semi-transparent silicone ear tips. The front edge of the case has an LED status strip, with a USB-C port on the back for charging purposes. The case also supports Qi-standard wireless charging.
Anker estimates around nine hours of playback on a single charge with active noise cancellation turned off, while the charging case holds an additional 19 hours worth of charge. Note that actual results may vary based on volume levels, usage of active noise cancellation, or spatial audio features.
In essence, the SoundCore Liberty 4 offers an excellent blend of aesthetics, functionality, and audio quality, making it an outstanding choice for anyone seeking high-quality noise cancellation in a true wireless design.
