The Grell Audio TWS/1 in-ear headphones are the brainchild of Axel Grell, who has spent a lot of energy creating decent Sennheiser products. The novelty entered the saturated market for fully wireless models under the name and brand of its creator.
First of all, the TWS/1 are equipped with the proprietary Grell Noise Annoyance Reduction (NAR) system, which is a patent pending. It’s complemented by Grell’s best-in-class Qualcomm Adaptive Noise Cancellation. In this case, NAR technology scans the noise spectrum and drives the ANC using a psychoacoustic model. The goal is the most comfortable sound environment.
Grell Audio TWS/1 features customizable 10mm drivers. From an acoustic point of view, unevenness is declared up to ± 1dB. The Qualcomm QCC5141 chipset with support for Bluetooth 5.2 and aptX, aptX HD codecs, not to mention AAC, SBC and LHDC, is responsible for the digital signal transmission.
Call quality in TWS/1 will be ensured by the patented Multi-Layer Air Suppression (MTE) technology. It is implemented by an advanced wind-proof microphone system.
The Grell Audio TWS/1 has a battery life of 28 hours. Of these, about 5 hours will be provided by the built-in rechargeable batteries of the headphones, which can be charged four times in the case. With ANC turned off, you get over 35 hours of music in total.
The Grell Audio TWS/1 will be sold only directly from the manufacturer’s website. In the US, the cost will be $200.
