Boult Audio is a little-known company that offers its audio products on the Indian market, including a wide range of wired and wireless headphones, headphones, and even sound bars. The twin pods that we tested some time ago proved to be a fairly cheap alternative to Apple's AirPods, especially for the market price. Today we're testing the Boult Audio ProBass Curve, a neckband wireless earphone that offers many features at a pocket-friendly online price of just Rs. 1.499.
This is a successor to the original curve, which has now been discontinued according to the company. The new model to which the name "ProBass" has been added looks physically identical to the older model. It is upgraded with Bluetooth 5 (compared to 4.2), but has no vibration motor in the neckband, which is probably the best – more on that later. Should this be your next budget? Let's find out.
Boult Audio ProBass Curve design and specifications
The packaging for the Boult Audio ProBass Curve isn't particularly good, but once you've reached the actual earbuds, the finish is better. The build quality is still average and the plastics feel a bit cheap. It is available in different colors, such as B. red / black, red / blue or even completely in black. The neckband is very flexible and snaps back into shape even when turning and turning at extreme angles. The earbuds are attached to wires that run along the neck band, and you can adjust the slack.
The ends of the neckband end in two plastic modules that house the battery and playback controls. The left module has a flap-covered micro USB connection, a microphone, a battery LED and three buttons for controlling the power supply and volume. As already mentioned, the newer model does not have a vibration motor for warnings, as was the case with the older model.
The earphones themselves are quite light thanks to their plastic housing and have a low profile so that they do not protrude from the ears. The silicone earplugs are comfortable and offer good insulation against ambient noise. In addition to the pair that comes pre-assembled, you get two additional pairs of earplugs in different sizes. There is also a micro USB charging cable in the box.
The outside of the earphones are magnetic so you can snap them together when you wear the band around your neck. These magnets are only used to hold the earbuds in place, and there are no additional functions such as. B. interrupting your music.
The drivers in the ProBass Curve are equipped with neodymium magnets. This headset is powered by Qualcomm's CSR8635 Bluetooth chip, which uses Bluetooth 5 to connect to your source devices. It supports Qualcomm's cVc noise cancellation technology for voice calls, but only the usual SBC Bluetooth profile for streaming audio.
The chip supports multi-point connections so that the ProBass curve can be coupled to two devices at the same time. However, there were times when the earbuds refused to connect to the second device. The company has not described in detail the frequency range that drivers can handle. The device itself has protection class IPX5 for moisture and sweat resistance, which is practical.
Boult Audio ProBass Curve performance and battery life
The ProBass Curve has a very good fit, which we liked immediately. We hardly felt the earplugs in our ears, and the neckband is also extremely light, so this headset is comfortable to wear even over long listening distances. The vibration engine of the previous model was very hard and uncomfortably messed up the band every time we turned it on or received calls and messages. Good thing that it was deleted from the ProBass model. You hear voice prompts through the headset when a device connects to it and when you turn it on or off.
The Boult ProBass Curve is tuned for punchy bass, and this is an area where it performs very well. Tracks like Lock Doh by Giggs offer a tight and controlled bass with a satisfying kick. No distortion occurs even at full volume. Vocals are rich and always sound as if they came from the front and from the middle. The midrange is generally decent, but complex tracks like Queen's Bohemian Rhapsody can be too much for the curve, as the highs and lows overwhelm the many background instruments. Highs in this track sounded a bit screeching even at full volume, although this is not a consistent problem for others.
The older Curve model, which we have had some experience using, temporarily lost connectivity, causing the audio to pause every few minutes. It's hard to say what caused this, but we saw it when we paired the device with several different devices, including a OnePlus 7 Pro (test) and an iPhone XR (test), and even a MacBook Air. Fortunately we didn't have this problem with the new ProBass Curve model. We also found it to have a good range, and we didn't have any connection issues with small obstacles between the headset and our source device.
One thing we noticed was that in order to get good bass response, we had to play around with the earphones a bit until we got a good seal. Simply sticking it in our ears did not guarantee a good fit. The controls are easy to find and master. A long press on the volume up button skips the track, while the same gesture on the volume down button takes you to the previous track. Since the power switch is also the play / pause button, you cannot activate the voice assistant on your phone.
The ProBass Curve automatically connects to the last recognized paired device. For a new connection, you must hold the power button down for more than five seconds until the light changes between blue and red.
The call quality is also pretty good. We didn't have any audio problems and the person on the other end didn't, even if we were in a noisy environment like a train station. The passive noise isolation of the earplugs is very good, but if you increase the volume to over 80 percent, there is a certain amount of noise loss.
Boult Audio promises a battery life of 8-10 hours on a single charge for the ProBass Curve. When using it, we easily managed to reach an average of 8 to 8.5 hours. Charging the battery via a laptop's USB port took a little over two hours. The power LED is the only indicator of the remaining charge level. It flashes blue when the level is above 20 percent and red when it drops below it.
The Boult Audio ProBass Curve replaces the outgoing model at the same online price of around Rs. 1,499, although we've sometimes seen it sell for a little less. For this price, this device has a lot to offer. It is sweat-proof, light and comfortable and has a good battery life. The mids are a little weak, but they produce clean and punchy bass. It is certainly not the highest quality device and it doesn't feel that way. Finally, the earplugs need to be played around a bit before you can get a good seal.
Overall, the Boult Audio ProBass Curve is a good choice if you are looking for lightweight, affordable Bluetooth headphones with good bass and moisture resistance.
