A relatively unknown brand, Boult Audio sells a variety of headphones, earbuds, and soundbars in the world market. We found the Twin Pods, a budget alternative to Apple’s AirPods, to be a respectable performer for their asking price after testing them out. Here is our Boult Audio Probass Flow review, a set of wireless neckband earbuds that sells for a highly reasonable price. 

This updated version has replaced the original Curve. The new version, whose name now includes “ProBass,” is indistinguishable from its predecessor. More on why it’s for the best that it doesn’t have a vibration motor in the neckband after all. Bluetooth 5 is an enhancement above Bluetooth 4.2. 

Boult Audio Probass Flow Review

Technical details of the Boult Audio ProBass Curve:

  • While the boult probass flow Curve’s box isn’t exactly a work of art, the earphones are finished to a higher standard. Plastics still feel cheap, and the construction is slightly above par. You may get it in various color combinations, such as red and black, red and blue, or black. The neckband may be bent and twisted in all kinds of crazy ways without ever losing its shape. The earbuds dangle from a choker through flexible wires that allow you to customize their length.
  • Plastic modules at each end of the neckband house the battery and media controls. The microphone, battery LED, and three control buttons (power, volume up/down, and volume down) are all housed in the left module, which also contains a Micro-USB connector with a flap covering it. In contrast to prior Curve models, this one does not include a vibration motor for notifications.
  • Their plastic casings make the earbuds surprisingly lightweight, and their compact design ensures they won’t get in the way. The silicone ear tips are soft and secure and do a fantastic job of blocking out outside sounds. In addition to the ear tips attached to the headphones, you get two more pairs in various sizes. Also included is a Micro-USB cable for charging.
  • When the neckband is not used, the earphones’ magnetic outer surfaces can snap together. The sole purpose of these magnets is to keep your earbuds in place; they do not serve any other purpose, such as halting your music.
  • Neodymium magnets power the drivers in the boult probass flow. The Qualcomm CSR8635 Bluetooth chip that powers this headset communicates with its connected devices through Bluetooth version 5. For phone calls, it uses Qualcomm’s cVc noise reduction technology; however, for music streaming, it just supports the standard SBC Bluetooth profile.
  • The probes Curve can be paired with two devices at once thanks to the chip’s capabilities for multipoint connectivity. On occasion, however, the headphones flat-out refused to pair with the additional gadget. The frequency range that the drivers can handle has yet to be specified by the manufacturer. As a bonus, the device can withstand splashes of water and sweat without damage.

Longevity and efficiency of the Boult Audio ProBass Curve’s battery:

  • The probes Curve’s snug fit was one of the first things that caught our attention. The earbuds were scarcely noticeable in our ears, and the neckband’s modest weight added to the overall comfort of this headset, even over extended listening periods. It’s a relief that the boult probass flow does not have the previous model’s vibration motor, which was very strong and shook the band uncomfortably whenever the phone was turned on or received a call or message. You will hear audible prompts when a device pairs with the headset or when you power it on or off.
  • The boult Probass flow Curve excels at providing powerful bass because this is one of its primary goals. Lock Doh, by Giggs, is an example of a song with a tight, controlled bass that packs a nice kick. Even at the maximum level, there is no audible distortion. Complete and clear vocals that are constantly placed front and center.
  • The previous model of the Curve, with which we have some familiarity, suffered from frequent connectivity loss that resulted in frequent audio interruptions. It needs to be clarified what exactly caused this to happen. Still, we noticed it when pairing the device with several different devices, including the OnePlus 7 Pro (Review), the iPhone XR (Review), and the MacBook Air (Review). With the new boult probass flow, you don’t have this problem.
  • Our testing revealed that a proper fit of the earphones was required to satisfy the bass response. We weren’t guaranteed a snug fit by just inserting them into our ears. It’s simple to locate and use the various settings. With a long push on the volume up button, you can skip to the next track, and with a long press on the volume down button, you can go back to the previous one..
  • If the boult probass flow detects a previously paired device, it will immediately establish a connection. To make a new link, press and hold the power button for at least five seconds or until the indicator light flashes blue and red.
  • In addition, the quality of phone calls is satisfactory. While the ear tips do a great job of blocking out ambient noise, you may notice some leakage if the volume is turned up past 80%.
  • Boult Audio claims that the boult probass flow Curve’s battery would last 8-10 hours on a single charge, and we consistently got around 8-8.5 hours of use out of a single control. It took over two hours to fully charge the battery using a laptop’s USB connector. The only indicator of battery life is the power LED. When the percentage is at or above 20 per cent, it flashes blue; when it falls below, it flashes red.


The boult probass flow Curve, which replaces the previous model, can be purchased online for the same price though you have seen it go for a little less on occasion. There’s a lot of value here for the money you’ll be spending on this gadget. It can withstand moisture and has a long battery life while still being lightweight and easy to wear. 

Although the mids aren’t powerful, the bass is clear and powerful. It appears and feels like something other than a high-end product. To conclude, some tinkering with the ear tips is required to get a proper seal. The Boult Audio ProBass Curve is a nice pair of Bluetooth earbuds if you’re looking for something light, cheap, good bass, and weather-resistant.
