The Mixcder E8 offers Bluetooth 4 connectivity using the SBC codec, active noise cancellation and a $70 price tag. It doesn't offer support for other codecs, nor does it provide more than stereo playback, which does seem reasonable for the price point. It does use standard 40mm neodymium drivers and offers 32 Ω impedance, with a battery which will offer 16 hours or more of playback.
TechPowerUp tested them and found them to be about what you should expect from a wireless ANS headset at this price, with one small caveat. The headphones offer a wired mode for extended use, however doing so disables the microphone.
"The Mixcder E8 is a pair of wireless, over-ear headphones with active noise cancelling, and a price that's much lower than you'd expect after going over the list of features. Just about everyone is after a pair of wireless headphones nowadays; here's something worth considering if you're on a tight budget."

Qualcomm has announced a new low-power Bluetooth SoC with the QCC5100 series, a single-chip solution targeting wireless earbuds and other audio devices with the promise of longer battery life and better audio quality than existing solutions. The QCC5100 integrates ANC (active noise cancellation), aptX HD audio, and 3rd-party voice assistant support, among other features.
Qualcomm Biometric Headset Example Design
Features for the QCC5100 from Qualcomm:
- Low power design and ultra-small form factor
- Dual-core 32-bit processor application subsystem
- Dual-core Qualcomm® Kalimba™ DSP Audio subsystem
- Support for aptX and aptX HD, Qualcomm TrueWireless Stereo, and Enhanced ANC (Feed- Forward, Feed-Backward, Hybrid)
- Voice Assistant Services, low power wake word detection
- Bluetooth 5.0 and 2 Mbps Bluetooth® Low Energy support
- Embedded ROM + RAM and support for external Flash memory
- 2-ch 98dBA headset class D (integrated amplifier)
- 2-ch 99dBA line inputs (single ended)
- 192kHz 24-bit I2S & SPDIF interfaces
- Flexible software platform with powerful new IDE support
Qualcomm Occluded Earbuds Example Design
Qualcomm says this new chip - a ground-up design with a quad-core processor architecture (2x APs and 2x DSPs) - offers power savings of up to 65% and provides up to 3x playback time of current Bluetooth devices on the market.
Qualcomm has shown device designs using the new SoC including occluded earbuds (no wire connecting the two) and a biometric headset, and while there are no announcements on shipping products Qualcomm expects to have examples for manufacturers in the first half of 2018.
