We have already tested a few Bluetooth kits from TrueBlueVoice earlier as well and were impressed with what they offered at that price. But the M22 is a mono aural unit unlike the stereo Bluetooth ones we earlier tested. However, TBV M22 is also the cheapest from the company’s portfolio.
This one is clearly aimed as an entry level kit for those buying a handsfree kit for the first time.
Design
There is nothing exciting about the design of the kit, though it is not ugly either. The device is curved and hugs the face of the wearer. There is a texture on the face of the device and the rest is plain black plastic. However, the problem is that the finish is not good and is not evenly cut. Even the power on button or volume rocker feels cheap. Though it will not hurt you it is the worst-finished device from TBV.
In terms of control, there is an on/off switch, a volume rocker, and a call button on the front. Buttons are well placed and give decent tactile feedback.
User interface
Being a monaural unit, it doesn’t have music controls. However, the interface is simple, and easy to connect to the phone. Just switch on the device; keep the call button pressed till the LED starts to blink; and then press ‘pair’ on your phone.
Taking a call or disconnecting it is also a single touch affair. Low battery and full volume indicators are beep tone, which is not as high tech as the kind of stuff some of the competitors are dishing out these days.

Sound quality
Though sound quality is decent with clear audio, microphone reception of the kit is not really good, and you have to adjust it at times to get your voice across. However, with adjustment it works fine. It also uses a dual-microphone algorithm, which suppresses both dynamic and stationary noise by 30 dB. The device uses software and CVC echo/noise reduction to produce high quality sound, but iffy voice reception spoils the party.
Connectivity
M22 handsfree uses the latest A2DP1.2 and AVRCP1.0 profile support to communicate with your phone. Advanced multipoint support allows a headset (HFP) connection to two phones for voice. The claimed distance, within which the kit works is 10 metres.

Battery
The TBV S70 lasts for up to 100 hours on standby and for up to 4.5 hours of talktime. However, since most devices claim to offer up to 10 hours, this is definitely not the best battery backup. 
The charging time of the device is not much, however. In 15 to 20 minutes it charges up to 80 per cent.

Conclusion
While we were impressed with other Bluetooth headsets from the company, this one seems to be lacking in some critical areas like microphone reception and build quality. Given the fact that at Rs 1,399 it is not the cheapest handsfree kit available in the market and comes from a relatively unknown company, further reduces its appeal. The only saving grace for this kit is that it offers noise cancellation and a two year warranty, which is not available in any other kit in this price range (others are way too costly).
