- Qualcomm QCC3020, AptX, AAC： The Sabbat E12 Ultra, with its Qualcomm QCC3020 chipset, Bluetooth 5.0 and AptX and AAC-playback support, offers a very decent 6 hours of playtime per charge. The case is also still able to recharge the earpieces at least four times fully.
- Outstanding Call Quality ： Sabbat E12 gives outstanding call quality. It's perfectly doable to have a longer conversation with these earphones. The other end of the line will hear some metallic reflection of his/ her own voice, but your voice comes through clear and background noise is suppressed wonderful.
- Substatially Balanced Sound And Details ： The Sabbat E12 ultra sounds lovely bassy, yet is substantially balanced and offers lots of detail. The soundstage is huge - with instruments and vocals coming in from everywhere, up close and far away. Not only is the sound spacious - it's also easy to place instruments in within the music. Listen to the Hell Freezes Over-variant from Eagles' Hotel California, and hear the music build up with cheering everywhere, guitars and cymbals on the left and right.
- Fine Connectivity & Tactile Button Control ： Small round tactile buttons can be found in the center of the lightweight earpieces. The controls are spot on. You don't have to push the earpieces too deep in your ears, and the feedback is great so that you won't activate unwanted functions. A single press plays and pauses music, press two times to skip (right) or return (left) a song, and three times to increase and decrease the volume. Hold the button, and you activate the voice assistant.
- One-Click Summon Siri Google Assistant： Smart life voice commands simplify your life, no matter you are driving or exercising, one-click connected with Siris Goole NowTM.
