Similar to prior models from AVIOT, the TE-D01g features a single 6mm dynamic driver with a graphene-coated diaphragm. Coupled with Bluetooth 5.0 and aptX codec support, the TWS is theoretically capable of delivery CD-like audio quality supporting up to 48 kHz / 16-bit LPCM audio data.
The TE-D01g exhibits coherence across the frequencies, providing a well-balanced output from the sub-bass to ultra-high frequencies. Depicting a warm sound signature suitable for various genres, the TWS is an all-rounder with a good soundstage that is wide enough with presence to allow accurate sound imaging for rather enjoyable listening.
At the low-end, the sub-bass was warm and soft all the way up 60 Hz, vibration is smooth but soft. It can be felt but the sense of contrast is low. Moving up to the lower-mids, there is the presence of depth but a distinct lack of definition, details and decay.
The TE-D01g depicts a more natural presence of vocals, piano, cymbal and strings at the midrange translating to better sound imaging on the soundstage. There is a slight bump at 3 kHz which is at the middle of the upper midrange again adding presence but not enough to cause listening fatigue.
The high frequencies starting from 4kHz seemed suppressed, allowing the midrange to be brought to the front with transparency which is positive for vocals, female vocals in particular though lacking in sparkle and airiness.
Lastly, between the two types of ear tips provided by AVIOT, the urethane foam ear tips will provide a better listening experience.
