Boult Audio Curve ANC Wireless in Ear Wireless Earphones with 25dB Active Noise Cancellation, ENC Mic, 30H Playtime, 60ms Low Latency Mode, Dual…

Good for price. But not to expect to work like JBL etc. But working good. Sound is ok. Battery is good. In this price segment. 4out of 5.
Music also good. Bass is average, treble too jus ok.
Buttons for play next, pause, call taking all good. Can adjust voulme also

This product is really good. I have used it and have good sound quality if you keep price in mind.

Audio quality is fine. Latency issues are not felt. ANC is not that good, but is okay considering the price. It partially eliminates constant noises like those made by fan. ANC microphones are placed on the center of the rearside of the earpieces, and adjusting the earpieces by pushing on them while ANC is ON results in white noises.

There is a small suspicion that the hole of the ANC microphone is letting in air and results in noises of that kind. Meaning, even though the ANC reduces noise, the ANC part lets in more noise when ANC is off, compared to a non ANC model. I’d suggest the Zcharge model if you dont want the subpar ANC. (actually the naming of the model is not right, Audio Curve ANC resembles the Zcharge model, not the Probass Curve model, hence it should have named Zcharge ANC.)

Fits comfortably in the ear. The earlobe supports are also good, as the ears doesn’t pain even after prolonged usage (one of them came with a small tear, but was nothing significant). Continued usage will offset the supports by some angle, which can cover the vent holes of the earpieces.

The magnets (which attach the two earbuds together) are too weak, that they detach even for small shocks and oscillations.

Charging speeds are fine, gets fully charged in around 25 minutes. Battery life is nowhere near the claimed 40 hours. Gets one whole day of battery life with a full charge for average use, without ANC. Battery percentage is not calibrated at all; gets like 10-15 hours of usage from 100% to 60% but only around 2-3 hours from 60% to 0%. (same with charging, in 2 minutes reaches 60% from nought, but takes more than 20 minutes for 60% to full charge). So never trust the battery percentage shown.

The build seems fine, not premium, but doesnt look cheap. The wires seems too thin, and looks like they may break at the point where they join the main body, especially considering the absense of strain reliefs, and the design choice where they are pointed up in a weird angle (but they look cool tbh).

Alright. So I have been using Boult ProBass Curve for over a month and would like to summarize my feedback in bullet-points to make it easy for the prospective buyers. I was thinking to buy a quality Bluetooth headset with a great performance at an affordable price for quite long and this is where my search ended. I was quite fed up of using cheap wired headsets as they used to go out of function or get snapped every now and then. Moreover, I found them getting entangled every other second making it really inconvenient to handle especially while travelling. Its that time I started feeling the need of a wireless headset and began my search. I took good time (months) to look for a good product. And, this is when I decided to purchase this item. Before purchase I devoted time to read the user’s reviews (that I always do before making any purchase-small or big) and found myself convinced. Finally, I decided to go for it. Ok. So, no more essay writing 🙂 Let me get straight to the key points:

1. I bought this for 999 under Sale so saved INR 499. (it’s a good saving. As Warrent Buffet says “every penny saved is every penny earned”)
2. This has great sound quality. I could not compare it against any other product because I don’t have any other bluetooth headset with me 🙂 But this will surely not let you down. It is very loud even at 80% volume level. You just cannot listen to at that level; forget about full volume. Bass is great but not outstanding to be honest but it does not disappoint either. Good thing is the sound does not distort even if you raise it to 100%. Excellent sound clarity!
3. I am not a technocrat so cannot tell what are the characteristics of noise cancellation feature but you will not get to hear any external sound/noise or very very minimal that is not noticeable. So, this stands perfect at this point.
4. Performs excellent while taking a call. You will a get a crystal clear voice when you make/take a call using this device. You will feel as if you are making calls directly from the mobile phone. In fact, it’s even better at times when the voice from the other side is low. I really love the hands-free calling because I have to take long calls with the clients in my job.
5. Battery backup is excellent!!! It can last anywhere from 10 to 11 hours. I have tested it rigorously in both audio and video usage. And, I mean it. I tested it for almost a month with day-wise log capture. Please see the detailed tracking at the end. It gets full charged in 2 hours approx.
6. Bluetooth range is good. It covers a distance of 10 to 15 feet easily. It’s quite enough if not good enough. My figures may be wrong. Beware! It’s just my rough estimate. Haven’t tested is rigorously.
7. Design looks good and is very convenient to wear. The wires are adjustable as per need. This is a nice thing. Looks cool when you wear it around your neck. I chose Red color.
8. Last but not the least. It comes with 1 year replacement warranty so you can sleep peacefully while enjoying your favorite music 🙂

Judgement: Just go for it if you have a limited budget or don’t want to spend a fortune on bluetooth headset. I was hesitant to spend anything beyond 1000 bucks on a bluetooth headset. It was my personal limitation.
