Overview

Our take on the Sennheiser CX 6.00 BT

Lightweight wireless in-ears, built for sound

The ultra-light Sennheiser CX 6.00 BT Bluetooth earbuds play music wirelessly and have real sonic chops. When I spoke to Sennheiser's legendary headphone designer Axel Grell, he told me that the company uses the super-premium models (like their flagship in-ears, the IE 800 S headphones) to inform the design of all of their headphones. These earbuds are tuned to deliver Sennheiser smooth highs, detailed mids, and healthy bass that's more complementary than overbearing.

Overview: The Sennheiser CX 6.00BT in-ear wireless headphones are designed for people on the go. They feature Bluetooth 4.2, and have an in-line remote and microphone on its 24" connecting cable for managing phone calls and music playback. The CX 6.00BT comes with four pairs of ear tips and a hard plastic storage case.

Bluetooth: You can wirelessly connect the CX 6.00BT to Bluetooth devices up to 30 feet away. The wireless headphones are compliant with Bluetooth 4.2, and backward compatible with all devices with Bluetooth 1.1, 1.2, 2.0, 2.1, 3.0, 4.0, and 4.1. The headphones feature the following profiles: Headset Profile (HSP), Hands Free Profile (HFP), Advanced Audio Distribution Profile (A2DP), and Audio/Video Remote Control Profile (AVRCP). The headphones can save the pairing information of up to 8 Bluetooth devices, including two simultaneously.

apt-X: Qualcomm's apt-X audio coding delivers the same high-quality sound as a wired connection, with crisp, full stereo audio playback. Qualcomm's apt-X Low Latency enables the headphones to deliver audio from portable video devices without a noticeable delay. You can enjoy videos and gaming with your portable device with high quality audio, in sync with the video.

The battery charges in approximately 1-1/2 hours, providing up to 6 hours playback time (A2DP) or 8.5 hours (HFP). You can check the remaining battery charge via the LED on the in-line remote. The battery life may also be displayed on the screen of your smartphone or device.

Connecting Cable: The left and right ear buds are connected by a 24" cable with an in-line remote and microphone.
