The Green Lion Rhythm X50 is a full-size, foldable wireless headphone with active noise cancelling, and this is the black version (Green Lion code GNRYTMX50BK). Green Lion rates its noise reduction at 30±3dB and fits the Green Lion Rhythm X50 with 40mm drivers, Bluetooth 6.0 and a 350mAh battery quoted at 30 to 50 hours of playtime. There are ANC, transparency and game modes, four microphones for calls and voice assistant support. Black is the colour for everyday use: dark ear cups and headband hide wear, and the look suits a commute, an office or a flight.

Black for everyday use
Black is the safe choice for a headphone you wear every day. Sweat, skin oil and the dust of a daily commute show far less on black cushions and a black headband than on a light finish, and the metal arms add a little contrast without drawing attention. If the Green Lion Rhythm X50 will live in a work bag, sit on an office desk and travel with you on flights, black keeps looking new the longest. It also goes with whatever you wear, from a work shirt to gym clothes, so it never clashes with an outfit.
Active noise cancelling: 30±3dB
Green Lion states a noise reduction of 30±3dB in ANC mode. Like any ANC headphone, the Green Lion Rhythm X50 works best on steady low-frequency sound such as aircraft engines, air-conditioning hum and traffic rumble, the kind of noise that fills a metro carriage or an open-plan office. Voices and sudden sounds are reduced less. Transparency mode does the opposite and lets outside sound in, so you can hear a station announcement or a colleague without taking the headphone off.
Battery: 30 to 50 hours, 1.5-hour recharge
Green Lion quotes 30 to 50 hours of playtime and 40 to 180 hours of standby from the 350mAh battery. It gives these as ranges and does not say which mode each end applies to; whether ANC is on and how loud you listen are the usual reasons playtime varies. Even at the lower figure, the Green Lion Rhythm X50 covers a working week of commuting or a long-haul return trip on one charge. A full recharge over the USB-C port takes 1.5 hours, according to Green Lion.
Calls, gaming and voice assistant
Four microphones handle calls, which helps the headphone pick out your voice on a busy street or in an office. Game mode is described by Green Lion as ultra-low latency, although it does not publish a latency figure in milliseconds. A voice assistant function lets you call up your phone assistant from the headphone. The connection is Bluetooth 6.0 with a 10-metre range, so the Green Lion Rhythm X50 pairs with any iPhone, Android phone, tablet, laptop or PC that has Bluetooth.
Sound and build
Inside are 40mm drivers with 32Ω impedance, a frequency response of 20Hz to 20kHz and a sensitivity of 119±2dB, all Green Lion figures. High sensitivity means the headphone reaches a good volume without your phone at maximum. The frame combines ABS plastic with metal, the ear cushions are padded and the headphone folds to pack into a bag. Green Lion does not publish the weight, the dimensions or the supported audio codecs on its product page.
Who This Is Not For
Skip the Green Lion Rhythm X50 if you need high-resolution codecs such as LDAC or aptX, or multipoint connection to two devices at once; Green Lion does not list them. Green Lion does not list a wired 3.5mm input either, so plan on Bluetooth only. As a full-size over-ear headphone it is not meant for running. And 30±3dB of ANC is good for the price, but it will not silence voices the way flagship headphones costing several times more can.
