-------------------------------------------------UPDATE:20/01/2018-------------------------------------------------It's been 5 months since I first got Boat Rockerz 400. Some of the dislikes I've mentioned earlier in my review are no more dislikes. I said the sound is more or less on a flatter side but I'm quite used to it and "I'm loving it".. :) the Second point is I said if you are an audiophile then you may not like it but I was wrong. You might ask why... Here is why:After a long gap, I visited my Father who is an audiophile. He has numerous high-end headphones but unfortunately, he got the attention of my headphone and he just wanted to try it. I said yes (I regret it :( ) he paired it with his device and played a song. Boy!! you got to see the grin on his face :D. He said I'm keeping it you buy another one. Poor me was forced to buy another one. A few days back I got another one :(One thing I noticed in two of my purchase isTHE AUDIO CABLE IS NO GOOD. Both my audio cable had the same issue.----------------------------------------------------------------------------So the moral of the story is: Hide it from your audiophile Dad or brother.. they will unceremoniously snatch it from you.Jokes apart, people, you can't go wrong with this purchase. It's worth every square inch.Happy Shopping...END OF UPDATE---------------------------------------------------I got this product 3 days back, and I got it for Rs. 1299( lightning deal of course) This is an honest unbiased review keeping in mind the price of the product:Three days might not be a sufficient time to review this product but sorry I can't help the excitement...----------------------------------------------------Likes:1> Good built quality------- 4/5It is sturdy, for the price the build quality is great. It is not flimsy. The ear cushions are good enough.------------------------------------------------------2> Sound quality------3.5/5If you are an audiophile this is not for you. Bass is decent nothing to go overboard( as noticed in other reviews). Bass is deep enough for the price.---------------------------------------------------------3> Connectivity: pairing is easy connects like a breeze.------ 4/5----------------------------------------------------------4> Dual Mode- Wired and wireless: Boat rockerz 400 comes with an aux cable.If you run out of charge you could always connect the aux cable and use it as a wired headphone. ( I couldn't find a substantial difference in the quality of music between wired and wireless though :) ) I absolutely loved this feature. ------5/5-----------------------------------------------------------Battery backup: I'm impressed with the battery backup of this beast. I've been using it for 3 days for 2-3 hrs a day still its running. So i guess the 8 hr backup per charge is not a marketing gimmick I presume it's true. So far so good. will update it after a month's usage.------------------------------------------------------------Dislikes:1> Sound quality is more on the flatter side. When you compare it with budget wired headphones like Sennheiser CX 180 Street II bass is not too deep. You won't get that ambiance. Boat's website says:"Don't just be loud, be loud and clear", Nope... sorry I've to disappoint you on this. When it's loud it's not at all clear. A lot of distortions are there when you are loud.-----------------------------------------------------------2> Comfort: Believe me, it's not at all comfortable for prolonged usage. Your ear will beg you to take it off after 30-45 mins.. If you have high fortitude you can push it till 1-1.20 hrs... If you could go more than that without taking it off for a minute then you are superhuman...-----------------------------------------------------------3> Range: Boats says 10 meters range... In my experience, if you go beyond 5-6 meters then the voice will break. You will never ever get 10 mtrs range trust me on that. And I'm experiencing occasional breaks in the streaming nothing intrusive so far but I don't know whether it will be a problem down the line. Will let you guys know about it later if it's a problem.------------------------------------------------------------- 4>Flimsy aux cable: I can't complain too much about the aux cable keeping the price in mind. Remember I paid only 1299 for it. But with certain devices, the aux was not working properly. Mi note 3 had issues, Mi 4 also had issues with aux. Not sure whether it's the problem with my device. But it worked flawlessly on my laptop.--------------------------------------------------------------5> Wafer thin service centers: Boat gives 1 yr warranty but what good is it if you can't find any service centers near you. This is a hit or miss guys...---------------------------------------------------------------6> Voice cancellation: I didn't find this effective. Maybe it's just me, not sure.----------------------------------------------------------------7> Microphone is pretty much useless. You can't make calls with this headset.-------------------------------------------------------------------Some alternatives:( These are all wired headphones, comparing them with a wireless may not be a good idea but still, I compare it with them because Boat rockerz comes with an aux cable, and if you are looking for an alternative irrespective of wired or wireless it might be of some use to you)1>Sennheiser CX 180 Street II : I don't think Boat can beat this one's quality. The sound is incomparable- the base is deep, nice fidelity, nice ambiance and for a price of 799 this is unbeatable budget wired in-ear headphone. I own 2 of this beauty. Total value for money. If you are an audiophile and are on a tight budget then I can't a better alternative than this.2> SoundMagic E10C In-Ear Headphones with Mic (Black/Gold): This is another TVFM earphone3>Sony Extra Bass MDR-XB250 On-Ear Headphones--------------------------------------------------------------------Don't buy it:1> If you are an audiophile ( obviously audiophiles will go only for wired headphones :D )2> If you intend to use it for long hours.----------------------------------------------------------------------Buy it:1> If you are looking for a budget wireless headphone with decent built quality and performance.2> If you require a wired and wireless package in one..-----------------------------------------------------------------------Verdict: I'd give this headphone a score of 3.75/ 5If you are on a budget and you want to enjoy a hassle-free Bluetooth headphone with good performance then CLOSE YOUR EYES AND BUY THIS BEAST trust me you won't regret it you won't be disappointed. In this price range, I couldn't find any other headphone with such a performance. We don't have many options.... Do we? :P :PThe actual price is Rs. 2999 and Amazon claim they are giving 57% discount. pls don't fall for that. I would not recommend paying more than 1700 rupees for this headphone.--------------------------------------------------------------------------Note: I'm not an expert in this field.
