As with previous models by AVIOT, the TE-D01g sports a Multi-Function Button (MFB). As the AVIOT models do not come with a companion app, the MFB is a preferred implementation. The TE-D01g also comes with voice prompts, it is however in Japanese unless you understand the language, it doesn’t really help.
Pairing the TE-D01g for the first time, the two earphones powers on automatically and enter into pairing mode with orange and white indicator blinking in an alternating fashion. A simple search on the smartphone will allow one to find “TE-D01g_L” or “TE-D01g_R” and select either for pairing. The earphones allow multi-pairing of up to 3 devices, this can be done by pressing the MFB two time consecutively on either side to pair with the second device, repeat the procedure if one would like to pair with a third device.
For music functionalities, you can press once on the MFB of either earphone to Play or Pause the music, press twice on the MFB of the right earphone to go to the next track and thrice to go to the previous track. To change the volume, press twice on the MFB of the left earphone to reduce the volume and thrice to increase the volume.
For voice call functionalities, one could answer and end calls with a single press of the MFB as well as reject calls by pressing and holding the MFB for 1 second. On the aspect of voice assistants, one could enable Siri or Google Assistant by pressing and holding the MFB for 1 second.
With the implementation of Qualcomm’s QCC3020, AVIOT extends the implementation of Qualcomm TrueWireless Stereo Plus to TE-D01g which supports the delivery of audio to both left and right earphones, an easy pairing experience where one can pair with one earphone and the other will automatically initiate pair as well as a reduction in power consumption, regardless of smartphone platform.
And if one uses a smartphone which is based on the Qualcomm Snapdragon 845 platform like the LG V40 ThinQ, which was one of the associated equipment used during this review, one can enjoy a superior listening experience aided by reduced latency and further reduction in power consumption as a result of evenly balanced power distribution between the earphones as well as the elimination of cross-head Bluetooth transmission providing improved robustness of the signal to each earpiece.
The advantage of the Qualcomm Snapdragon 845 platform is evident during the review process, the TE-D01g registers an average battery life of 9 hours, 24 minutes and 12 seconds when paired with an LG V40 ThinQ compared to the average battery life of 8 hours, 38 minutes and 14 seconds when paired with a Huawei Mate 20 X. In the area of audio latency, there was also noticeable improvement when the TE-D01g is paired with an LG V40 ThinQ where latency was unnoticeable compared to the slight but noticeable latency when paired with the Huawei Mate 20 X.
During the review process, the TE-D01g registers an average battery life of 9 hours, 1 minute and 13 seconds. While this is short of the 10 hrs stated by the company’s specifications, it is still one of the longest battery life I have experienced on a True Wireless, particularly if one takes into consideration that this is an entry-level model and aptX was enabled throughout. Furthering the aspect of battery life, the company also added a quick-charge feature to the TE-D01g, providing a battery life of 3 hours to the earphones after 10 minutes of charging in the charging case.
Based on the average battery life registered during the review process, a pair of fully charged earphones coupled with 5 full charges in the case will ensure a total of 54 hours, 7 minutes and 18 seconds playback time before a recharge is needed.
