    Why anyone buys a Bluetooth earphone?
    … So that they can do their work freely while having earphone on. Imagine the voice continuously breaking while you have that plugged into your ears listening to your favorite song.
    I assure that is one of the most annoying thing you can experience.
    This is the only issue with the phone…if you are stationary, all ok…In a straight line without anything inbetween the range is 4-5 Metres.
    Don’t even think of jogging with this product.

    I am editing my comment further after a months use, the connection issue is really troublesome.
    Even when stationery, it keeps on disconnecting.
    If your hand comes between the phone and earphone, the voice breaks completely.
    Never seen anything like that in any wireless earphone before.

    Two major issues: 1) Bluetooth connection stability: this device connects instantly but while on the move the audio is constantly interrupted. Even if I keep my hand on the pocket the phone is kept, it interrupts audio (while walking). And not only for few seconds, but it keep on interrupting through out my walk. If I’m using it with the phone in front of me it’s awesome, but not at all good while walking.

    2) Direction of sound: It lacks a very fundamental concept of direction of sound. Left earpiece produces sound coming from right and vice versa. First I had doubt, while playing game. Later on checked using 5d sound test and now confirmed that both earpiece produces sound coming from opposite direction. Left earpiece produces sound coming from right and Right earpiece produces sound coming from left.

    Used this device for approximately a week.

    I am writing this review after I placed a replace request. I would try the replaced set and if the issue remains same, I would like a refund.

    Received the replacement and found same issue with the replaced set too.

    Update: I requested a refund of the replaced product. Delivery boy collect the product from me…… now after some day, when I enquired about my refund, to my surprise I got to know that the seller updated amazon that I returned a non amazon product……..

    Update: I have not yet received my refund and Amazon says they are still working on the matter.

    Update: the issue is now resolved and the refund is processed by Amazon.

    Actually this product is myntra exclusive.The price in myntra was around 1800(including tax).

    Packing :
    The packing is perfect with earphones placed securely.the packing itself looks premium.

    Box contents :
    Boult audio earphones,a small USB cable to charge,user manual, warranty card(1year warry) and 2 pairs of extra ear tips(small and large).

    First impression :

    The earphones look very good and elegant.feels very light in hands.the neck band is made of some soft kind of plastic which is very comfortable to wear.the ear piece is made of metal and looks good and hard.the ear pieces can be attached together by the magnets.the magnet is good enough to hold them tight.the color of earpiece looks good and gives kinda premium look.

    Buttons :

    The brick on the right side has the buttons.
    We get 1 multifunctional button (the middle one)which can be used to power on and power can also attend the calls and end the calls by single pressing them.while playing music you can pause/play by single press.
    You can adjust the volume by the the 2 buttons which is either side of the multi functional button by single pressing.long press changes the tracks when music is being played.

    Connectivity :

    Pairing your boult with your mobile is very easy…just press and hold the power button on the boult untill you feel the vibration twice.turn on the Bluetooth option on your mobile… search for devices and you’ll find ‘boult audio’ just tap it and you’ll be paired.also you can hear an audio that your are being connected.


    The company has not specified anything about the capacity of the states that it has 12 hours of playback.yes,the battery backup is good on this.we can easily get 12hours of play time through this earphones.

    Additional features :

    These earphones come with built in vibration.whenever you receive a call the earphones will start vibrating. I have to tell you,the vibration os really strong and can easily be Know even if you are in busy (like traveling in bike,or a busy street)
    But remember if you’re getting calls continuously it’ll less the battery backup.

    Sound quality :

    Sound quality in these earphones are amazing.
    The mids are crisp and clear, the vocals are good the bass is also heavy but it’s that not punchy.but don’t you can adjust the equalizer and have that punchy base.
    The call quality is also good because of the condenser microphone .
    These earphones have noise cancellation which works good.the volume level on these earphones are really high.i cannot go beyond 80% when I’m in office. When I’m on streets I can use full volume to make that noise isolation work.

    These boult earphones are really budget friendly and has some good premium features.
    If you’re budget is around 1500 these are the best earphones.
    there are no concerns according to me till now .
    I’ll update when something goes wrong.

    Update !!!

    So im using this product for almost 1 year and found no major issues . Except for the battery drop after 8months.

    As i mentioned,it came with the vibration on calls option , but the models which they’re selling now doesn’t have this feature.

    Thank you
