Description

When it comes to sound quality, Sennheiser didn’t hold anything back. The CX 400BT headphones give you the same dynamic 7mm drivers and acoustic technology as the MOMENTUM True Wireless 2 headphones, in a more affordable package. This includes support for aptX, which is designed to give you high-quality wireless audio playback. You can also use the Smart Control app to create your own EQ presets, fine-tuning audio settings for different genres.

As with all True Wireless headphones, the CX 400BT includes a convenient wireless charging case for extra power—power you may not even need because the earbud’s own 55mAh batteries deliver up to 7 hours of continuous playback for your favorite songs and podcasts. If you do need more, the charging case’s 420mAh battery provides an additional 13 hours of power. The case also offers a quick-charging option when you’re in a hurry. Only 10 minutes of charging ensures up to an hour of audio, or get up to 5 hours with a single hour of charging.

In addition to enjoying music and other audio entertainment, the CX 400BT headphones provide more practical benefits with the inclusion of dual built-in MEMS microphones. When paired with your Bluetooth-compatible mobile device, you can use these microphones to speak voice commands to digital assistant software. If that device is a smartphone, you can make hands-free calls, as well.

Comfort is another primary feature of the new CX 400BT wireless headphones. Four different-size pairs of soft, silicone ear tips let you choose the fit that suits you best. With custom controls, EQ presets, and multiple ear tips, the CX 400BT sets themselves apart from the pack, giving you a pair of everyday headphones that can be made to suit your lifestyle.

Sennheiser gives you two colors to choose from. The CX 400BT True Wireless headphones are available in either white or black. The company also offers a host of accessories and extra parts. Grab a spare charging case in white or black, or individual earbuds that also come in white or black. If you need extra ear tips, a 5-pair pack of black ear tips can be obtained in various sizes, including small, medium, and large.
