True Blue Voice TBV M-21 Hands on Review

I need a Bluetooth Device and was low on Budget, Then True Blue Voice M21 Bluetooth Device came out of Light, and on an offer Deal , i bought this at Rs 299. It features Headset Profile 1.1 and Bluetooth 2.0 + EDR (Enhanced Data Rate).
In the Box:

  • Bluetooth Device
  • Ear Hook
  • User Manual
  • small pin charger similar to Nokia 


  • Budget Friendly
  • small in size
  • Less weight around 8 grams
  • 4 hours battery backup
  • Ear hook get loose after using for somedays
  • Sometimes Bluetooth not detect Charger
  • Lack of service center in India, only one are in Mumbai and Bangalore
  • Very small font in user manual
After Unboxing the Device , We have to press the Power Key for 10 seconds or till the Blue LED indicator becomes stable. This makes the Device Discoverable. On my Nokia 2700 Classic it appears under Bluetooth Audio enhancements as "TBV-M21". To Turn off the Device/Disconnect you need to press Hold/power key for 10 seconds or until Red Led blinks 3 times.

On Nokia and Some other Features Phone, you can use it to listen Music as well as to attend Calls, but in Android it is only usable to attend Calls , you can't use it to listen Music.

Signal Reception:
it can be used from a distance of 15-18 Feets after that signal become erratic.

After Sales Service:
After sales service of True Blue Voice India is awesome, as I can't figure out how to make device discoverable and supposed that the Device is faulty , I sent it to Bangalore Service Center, there Team Fully Co Operate on the Phone . Only drawback is lack of Service Centre in India and hope company will setup soon.
