Each bud weighs 6.2 g, runs a 7 mm TrueResponse dynamic driver, is rated IP54 for dust and splashes, and charges from a case that takes both USB-C and Qi wireless.\u003c\/p\u003e\n\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\n\u003ch3\u003eBluetooth 5.4 with aptX Lossless and LC3\u003c\/h3\u003e\n\u003cp\u003eSupported codecs are SBC, AAC, aptX, aptX Adaptive\/Lossless and LC3. LC3 is the new low-power audio standard, while aptX Lossless carries a lossless stream when conditions allow — both depend on your phone supporting them. Sennheiser lists Auracast as available via firmware update only, so it is not an out-of-the-box feature.\u003c\/p\u003e\n\n\u003ch3\u003e7 mm TrueResponse drivers\u003c\/h3\u003e\n\u003cp\u003eEach bud uses a 7 mm TrueResponse dynamic driver covering 5 Hz to 21 kHz, rated at 107 dB SPL (1 kHz \/ 1 mW) with THD below 0.08% at 1 kHz \/ 94 dB. That distortion figure is low for a true wireless earbud, and it shows in vocals and strings that keep their detail instead of sounding compressed.\u003c\/p\u003e\n\n\u003ch3\u003e30 hours total and wireless charging\u003c\/h3\u003e\n\u003cp\u003eThe buds run up to 7.5 hours with ANC off and up to 7 hours with ANC on, for up to 30 hours of total playtime with the case. Batteries are 75 mAh per earbud and 820 mAh in the case. An 8-minute quick charge returns about an hour of playback, and the case accepts USB-C or Qi wireless charging.\u003c\/p\u003e\n\n\u003ch3\u003eThree mics per bud, IP54, app control\u003c\/h3\u003e\n\u003cp\u003eEach earbud carries three microphones with beamforming, feeding a hybrid adaptive ANC system. The IP54 rating covers dust and splashes, which is enough for hiking, running or walking through rain, though not for swimming. The Sennheiser Smart Control app on iOS and Android handles tuning and settings.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:16px 0\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding:8px 10px;border:1px solid #ddd;background:#f6f6f6\"\u003eItem\u003c\/th\u003e\n\u003cth style=\"text-align:left;padding:8px 10px;border:1px solid #ddd;background:#f6f6f6\"\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #ddd\"\u003eTransducer\u003c\/td\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #ddd\"\u003eTrueResponse dynamic, 7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #ddd\"\u003eFrequency response\u003c\/td\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #ddd\"\u003e5 Hz – 21 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #ddd\"\u003eSensitivity\u003c\/td\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #ddd\"\u003e107 dB SPL (1 kHz \/ 1 mW)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #ddd\"\u003eTHD\u003c\/td\u003e\n\u003ctd style=\"padding:8px 10px;border:1px solid #ddd\"\u003e\u0026lt;
