New wireless Grell TWS / 1 in-ear headphones offer truly great battery life – backed by a former Sennheiser employee

The fully wireless Grell TWS / 1 headphones offer up to 45 hours of use complete with a charging case.

New Grell TWS / 1 headphones in the background is Axel Grell, a headset designer who previously worked for Sennheiser. He left Sennheiser the second year to start his own Grell Audio company. The new TWS headphones are the company’s first product.

Features of the Grell TWS / 1 Wireless Headphones include active anti-noise function and Bluetooth 5.2 support. Codec support is nicely extensive, with SBC, AAC, aptX, aptX HD, aptX and LHDC supported. In addition, the headphones are splash-proof according to the IPX4 rating. The headphones use 10.1 mm elements. The headphones can be controlled with touch control.

Battery life is promising, as without back noise, the battery lasts up to 45 hours when charged from an aluminum housing, and 34 hours even when the ANC is switched on. Without refueling, the buttons are promised to last six hours of listening with back noise turned on.

The buttons hit a clearly higher price range, as they cost 200 euros. The headphones are already pre-orderable.
