Grell Audio TWS1: Combined Noise Cancellation and Wind Shield

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.
