Oppo Enca Air 4i: Environmental autonomy headphones for less than 40 €?
In China, Oppo has just unveiled the Enca Air 4i, headphones True Wireless whose price/performance ratio would challenge any competition. Despite their naturally insulating semi-ear format and promoting sound quality, they would be even cheaper than range entry headphones in the ENCA Air 4 button format.
Even if the OPPO headphones register as inexpensive alternatives to the AirPods, we should not expect a plethora of features and high -flying sound performance for these 4i air. However, according to the information we have, certain aspects of their technical sheet would make them rather interesting.
12 hours of autonomy, low latency and contained weight
According to the Chinese brand, the ECO Air 4i would be able to offer a very substantial autonomy of 12 hours for a single load, extended to 54 h thanks to their box. These performances are of course announced without the noise reduction, since the ECO Air 4i do not have one. Oppo also evokes IP55 certification giving them better resistance to water and dust than a wide variety of high -end headphones.
Connectivity is not surprisingly very basic, with a simple 5.4 Bluetooth receiver only compatible with the AAC and SBC codecs. However, it would be possible to reduce audiovisual latency to “47 ms“Thanks to a owner mode available via the App Oppo. In terms of sound architecture, the 4i AIRCA AIR is equipped with 12.4 mm transducers with dimensions a little more contained than those of the 3i APT. would give access to a 6 -band equalizer for sound customization, while their almost record weight of 4.3 g could offer comfort adapted to long listening sessions.
