It pairs 37 mm dynamic drivers with hybrid active noise cancelling and up to 50 hours of playback with ANC running, in a 222 g body. Codec support reaches aptX HD, which is more than its position in the range would suggest.\u003c\/p\u003e\n\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\n\u003ch3\u003e50 hours of playback, 10 minutes for 5 hours\u003c\/h3\u003e\n\u003cp\u003eSennheiser rates it at up to 50 hours over Bluetooth with ANC on. A full charge takes around 3 hours, and a 10-minute top-up returns up to 5 hours of music. On a two-hour daily round trip that works out to charging roughly once a week rather than remembering a cable every night.\u003c\/p\u003e\n\n\u003ch3\u003eA codec list that includes aptX HD\u003c\/h3\u003e\n\u003cp\u003eBluetooth 5.2, class 1, with SBC, AAC, aptX, aptX HD, mSBC and CVSD. aptX HD raises the bitrate ceiling above standard aptX, which Android users notice on local lossless files and higher-rate streams; iPhones use AAC. mSBC and CVSD are the call codecs.\u003c\/p\u003e\n\n\u003ch3\u003eHybrid ANC and beamforming mics\u003c\/h3\u003e\n\u003cp\u003eNoise cancelling is a hybrid system sampling from both inside and outside the cup, which is most effective against the steady low-frequency rumble of the MTR and buses. For calls there are two MEMS microphones with beamforming, covering 50 Hz to 8 kHz — enough for daily video meetings and phone calls.\u003c\/p\u003e\n\n\u003ch3\u003e37 mm drivers in a 222 g body\u003c\/h3\u003e\n\u003cp\u003eThe 37 mm dynamic drivers cover 10 Hz to 22 kHz at 106 dB SPL (1 kHz \/ 0 dBFS), with THD under 0.3% at 1 kHz \/ 100 dB SPL. At 222 g the headphone is on the light side for a closed ANC over-ear.

Both use hybrid ANC, both are Bluetooth 5.2, and both are supported by Sennheiser's Smart Control apps. For everyday commuting the gap is smaller than the spec sheet suggests.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat do I need for aptX HD to work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYour transmitting device has to support aptX HD, which in practice means certain Android phones and digital audio players. iPhones do not support the aptX family and fall back to AAC, which still sounds perfectly normal. Check your handset's codec list before buying.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes maximum ANC feel oppressive?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHybrid ANC works hardest on continuous low-frequency noise, and some people sense pressure on the ears when a room goes completely quiet.
