Redmi SonicBass Wireless Earphones Review

Xiaomi’s strategy means the company now has two key brands under its core banner – Mi and Redmi – with all of its products categorized into one of the two families. The Redmi brand is the cheaper of the two, while Mi branded products are slightly higher quality. Indeed, the company’s cheapest smartphones and audio products sport the Redmi emblem. This includes a recently launched audio product, the Redmi SonicBass Wireless Earphones, priced at Rs. 1,299.

After the introduction of the Redmi Earbud S and other competitively priced products, the Redmi SonicBass wireless headphones promise a more traditional headphone style at a popular price point, along with the bass-focused sound signature that many buyers seem to prefer. How do these affordable wireless headphones sound? Find out in our review.

There’s not much to talk about when it comes to design. This is almost the most useful pair of wireless headphones you can buy

Simple, functional design of the Redmi SonicBass Wireless Earphones

The Redmi SonicBass wireless earbuds really don’t offer much in terms of design and design. This is as simple and basic as it gets. The neck strap is flexible at the back and has larger, solid ends that house the bluetooth hardware, battery, and audio circuitry. A barely noticeable Redmi logo is engraved on the left end, while the power and volume buttons, the micro-USB port for charging and the indicator light are attached to the right.

You can buy the Redmi SonicBass earbuds in one of two colors: black or blue-black. While the black was a bit more subdued and discreet, the two-tone blue and black option might appeal to buyers looking for something colorful. Although the earbuds are comfortable to wear, the cables running between them and the neckband tended to get in the way and brush against my face, which caused some cable noise.

The main button plays and pauses music, or answers and ends calls with a single press. You can call up the standard voice assistant on your smartphone by pressing twice. A long press turns the headphones on or off. If you keep pressing the Redmi SonicBass for a few more seconds, it will go into pairing mode. The earbuds attach to each other magnetically, but this doesn’t control performance like some other headsets do. It’s just meant to keep the wires from tangling when they’re not in use.

The sales package contains a total of three pairs of silicone earbuds (the middle ones are pre-assembled on the headphones), but there is no micro-USB cable for charging. Even at this price point, skipping a charging cable is unfortunate. Not everyone necessarily has one at home, especially those buying affordable entry-level products.

The Redmi SonicBass wireless earbuds use bluetooth 5 and only support the SBC bluetooth codec. AAC support would have been nice here, but I’m not going to go as far as to say that given the price, it’s a shortage. Interestingly, there is a multipoint connection that allows you to pair the Redmi SonicBass earbuds to two source devices at the same time. This worked well and I was able to quickly switch between my smartphone and laptop while using the headphones.

The battery life is sufficient for the price. The Redmi SonicBass wireless earbuds run for around 10 hours on a charge, and it takes around two hours to fully charge with a wall adapter. The headset is IPX4 certified for water resistance and should be able to handle sweat and light splashes of water.

Punchy bass on the Redmi SonicBass Wireless Earphones

The product name itself is a great giveaway in terms of what to expect when it comes to sound, and in fact, there are no surprises here. The acoustic signature is tuned to give a boost to the low-end frequencies, and I could sense this bass tendency in pretty much everything I’ve heard with the Redmi SonicBass headphones. It’s worth noting, however, that the sound doesn’t contain much other than that bump in the bass. Otherwise, these are normal sounding headphones.

That’s not a bad thing, however, as the Redmi SonicBass has all of the basics. You get a pleasant sound that is in no way tiring or strange. This makes for a decent listening experience that goes well with the price and functionality of the headphones.

The Redmi SonicBass is an affordable wireless headset and only supports the SBC Bluetooth codec, so the quality of the source audio had little impact on the listening experience. Whether you’re listening to high definition Tidal Masters streams or the occasional low bitrate music from YouTube Music, there wasn’t too much of a difference in the sound of the headphones.

Hearing the gorgeous Golden Brown from The Stranglers across streaming services confirmed this, but it didn’t detract too much from the sound quality given the price of the Redmi SonicBass headphones. As expected, the lows were more pronounced, with the drums reverberating noticeably in the track. The mid range and highs sounded a bit dull compared to the lows, but weren’t unduly overwhelmed. The headphones created a secure acoustic signature that was never offensive or muddy.

Barry White’s Never Never Gonna Give You Up sounded similarly interesting with references to directionality. Some of the gentler elements on the track felt spacious, but the bass tendency tended to limit the soundstage. There wasn’t much to do with the imaging or the details. Tuning the Redmi SonicBass earbuds was about keeping things clean and comfortable, rather than trying too hard to offer more and falling short.

While this is no exception for voice calls, the Redmi SonicBass wireless earbuds are designed for this purpose. Ambient noise cancellation is in place and always on when you’re on the phone, but it didn’t seem to make much of a difference in improving voice quality for people on the other end of the call, while to me they sounded a bit booming and quiet. The headphones were good enough for casual calls and could be used relatively well at distances of up to 12 feet from the source device.

Often, the biggest mistake affordable audio manufacturers make is over-selling and getting the basics wrong. Xiaomi didn’t do that with the Redmi SonicBass. These are fully functional wireless headphones that will get the basics right. The fit and design are workable, the strong bass will appeal to many listeners, and the multi-point connectivity makes the headset much more useful. Overall, there are only a few minor drawbacks.

Though priced at Rs. 1.299 officially the Redmi SonicBass Wireless Earphones are available for Rs. 999 at the time of writing this review which quite simply makes this the best pair of wireless earbuds you can buy for less than Rs. 1,000, and still a pretty good deal, also for Rs. 300 more.
