Astell & Kern (A&K) announced the true wireless earphones AK UW100, the latest addition to the product range which also includes very high-end (wired) proposals such as the AK Zero1 in-ear monitors. The external appearance is modeled on a pentagonal shape which then expands outwards forming a sort of pyramid point.
The earphones they weigh 7 grams each and have a touch sensitive surface to control all functions. Within each element we find a balanced armature transducer made by Knowles. The digital-to-analog conversion is entrusted to a DAC AKM AK4332ECB 32-bit by Asahi Kasei.
Instead, wireless connectivity is handled by a chipset Qualcomm QCC5141capable of supporting the Bluetooth 5.2 with HFP, A2DP and AVRCP profiles and SBC, AAC and aptX Adaptive. The highest supported quality is 420 kbps at 24-bit. You can combine various devices thanks to the Multi-Pairing and up to two products simultaneously with the Multi-Point. The data sheet reports a maximum sound pressure of 94 dB (1 m @ 1 kHz).
The UW100s are designed to guarantee a passive isolation from external noise. There are therefore no active technologies that cancel certain frequencies. They are still present two microphones for each headset, useful both for calls and for activating the Ambient Mode. For calls A&K has integrated the Voice Communication Package (VCP) developed by Alango and based on technologies Acoustic Echo-Canceller And Noise-Suppressorcapable of eliminating echoes and reducing background noise.
L’Ambient Mode it is activated with a touch on the left earpiece and allows you not to isolate yourself from the surrounding world; with a double tap you scroll through the four modes present, in order to pass the desired amount of sounds. Alternatively, you can use theapplication for iOS and Android; it contains various settings such as touch control management, equalizer and firmware updates.
Autonomy reaches 6 hours of operation to which they must be added another 18 hours using the supplied case. The port can be used for charging USB-C or a wireless charger. Fast charging takes 10 minutes to ensure one hour of listening. The package includes 5 different sizes for the rubber pads. The list price is set indicatively aa 260 euros. We remind you that Astell & Kern products are distributed in Italy by Audiogamma.
