Sennheiser MOMENTUM Free Neck Chain Style Earphones

Friday, November 10, 2017

The MOMENTUM Free by Sennheiser are in ear headphones with magnetic earpieces that can be joined together and worn around the neck when not in use..
The MOMENTUM Free Bluetooth 4.2 headphones deliver wireless hi-fi sound via Bluetooth 4.2 and Qualcomm apt-X low latency, which greatly minimizes Bluetooth audio lag when watching YoutTube videos.
The microphone chip (aka MEMS microphone), which is integrated on the other side of the remote control features Bluetooth hands-free profile 1.6 wideband audio (a.k.a HD Voice) for high definition voice quality audio.

HFP 1.6 wideband essentially doubles the voice bandwidth from 3.4kHz (narrowband) to 7 kHz or higher. You also get Bluetooth Headset Profile (HSP 1.2), giving you the ability to ring, answer a call, end a call and adjust the volume.

The MOMENTUM Free built-in microphone really does a superb job at transmitting very clearly your voice, as well as delivering your voice fairly loud in both wideband and narrowband communications.
Send Loudness Rating: 10dB +/- 5dB (wideband) and 8dB +/- 5dB (narrowband)

The voltage produced by the MOMENTUM Free microphone is 6.3 mV (millivolts) at 94dB Sound Pressure Level (SPL). This gives the microphone a sensitivity of -44 dB V/Pa which is the same crystal clear microphone quality you get with the built-in mics in the MOMENTUM on ear headphones and MOMENTUM in-ear neckband.
MOMENTUM Free can connect to 2 devices simultaneously
The MOMENTUM Free headphones also feature the latest versions of Audio/Video Remote Control Bluetooth Profile (AVRCP 1.4) and Advanced Audio Distribution Bluetooth Profile (A2DP 1.2), which further enhances the sound quality of the audio over Bluetooth.
With AVRCP version 1.4, you get all the benefits of version 1.3 which include status of the music source (playing, stopped, etc.) and track information (artist, track name, etc.), as well as absolute volume and media player browsing for multiple media players (including a "Now Playing" list).

The nozzles and internal housing of the dynamic speaker drivers are machined stainless steel with mirror chrome accents on the outside. The rubberized rings on the back of the housing provides a more secure grip in the fingers when fitting the earphones in the ears.

The sound stage signature of the MOMENTUM Free is wide and natural thanks to a wide frequency response range from 15Hz to 22000Hz which allows for deep bass frequencies and detailed vocals and instruments.
The battery box is also located in-line but isolated from the rest of the unit. The battery box integrates a 85mAh rechargeable lithium polymer battery which powers the MOMENTUM Free for a good 5 hours on moderate volume.
