Sennheiser has been focusing on the wireless segment in recent times. It sees a big opportunity with people who enjoy the convenience of having a wireless audio device while on the move, connecting to their music as well as calls. While it has cut the cords on most of its range, it is also experimenting with new designs like the neckband, which it has introduced even in the Momentum range. But then the Sennheiser Momentum neckband is a luxury product and not for everyone and that is where the new Sennheiser CX 7.00BT wireless neckband headset may have an opportunity. I am a fan of the neckband design because it keeps all the wires away. Often when you are using a headphone on the move, a lot of effort is spent keeping the wires in order. However, the neckband design popularised by LG has been gaining popularity for its ease of use. While Sennheiser introduced the neckband in the Momentum range, the leather finish ensured it could not be used for workouts. The CX 7.00BT does not suffer from that issue and can be used in all circumstances, thanks to its plastic body. Like the Momentum, this one too does not have retracting earbuds. The controls are on the left and there is a flap at the end from where it can be charged with a micro USB cable. Specifications: Frequency response: \u00a017Hz \u2013 21,000Hz Sound pressure level: \u00a0112 dB (1 kHz\/0 dBFS) Total harmonic disruption: \u00a0<0.5% (1kHz\/100dB SPL) Pick up pattern: \u00a0Omni-directional Supported profiles: A2DP + AVRCP + HSP + HFP Connection: Bluetooth 4.1, NFC Battery: Rechargeable Lithium-ion Polymer (170mAh) Estimated street price: Rs 9,592 I had a bit of an issue keeping the silicone tip in place inside my right ear. I suggest you try out the best fit before settling in. In the box, there is a fabric case for the band. Don\u2019t forget this, because the cord of the CX 7.00BT could get damaged inside a bag. The CX 7.00BT is made for those who enjoy hi-definition audio and the Qualcomm apt-X codec offers great clarity and ambient sound despite the unit being wireless. I tried the CX 7.00BT in various situations \u2014 in cars, planes and inside my house and office. The experience was truly top class. The CX 7.00BT offers a depth you would not expect in a device like this. Also, the silicone tips keep most of the noise out. I loved how the CX 7.00BT offers a good balance of bass and does not overpower you. I found it ideal for soft, vocal-based numbers. CX 7.00BT is a good option for those who want wireless comfort, but not at the cost of audio quality. While the Momentum is better if you are looking for a headband, this model is one you can use everywhere.
