Sennheiser CX Truly vs Realme Buds Wireless [Review]

Whether you’re searching for wireless earbuds to use while exercising or a pair of noise-cancelling earphones to shut out the world around you, we’ve got you covered with our list of the finest models available today. Additionally, we examined for earbuds that sound excellent, have a long battery life, and are inexpensive if you’re on a budget.

Continue reading as we walk you through all of your choices. There is a lot to take in, but we’ve whittled it down to the very finest.

1) Sennheiser CX Truly Wireless review

The Sennheiser CX Truly Wireless is the German audio giant’s newest wireless earphones. They continue where the CX 400BT left off, being less expensive than its predecessors while offering a slew of enhanced features such as longer battery life and improved connection.

The CX 400BT was already a very capable pair of truly wireless earbuds, with a wide soundstage and responsive touch controls – and the CX True Wireless outperform them in almost every aspect.

Sennheiser’s audio quality is precisely what you’d expect, with a spacious soundstage, crisp mids, detailed trebles, and strong bass tones. Nonetheless, we were pleasantly pleased by how well these earphones sounded considering their pricing. While audiophiles may like a more balanced soundscape (the bottom end is very prominent), the Sennheiser CX delivers a really pleasant listening experience.

The controls and accompanying software are very user-friendly, and Bluetooth 5.2 connectivity guarantees a reliable connection to your smartphone. Additionally, high-resolution audio support is provided for those looking to extract every single detail from their music.

Our only major criticism is the design of the CX True Wireless, which we felt to be much too bulky for our ears – to the point where they were uncomfortable to wear at times. We’re reluctant to pass judgment on Sennheiser for this since the majority of consumers will likely be able to utilize them without incident. Simply be aware that if you have smaller ears, the CX True Wireless may feel unpleasant.

Even yet, this is insufficient to dismiss these earphones. You get outstanding audio performance, a long battery life, simple controls, a useful app, and an amazing connection for the price.


The Sennheiser CX True Wireless maintains a similar style to the previous generation, with a more utilitarian appearance that will appeal to minimalists – but not as much to those who want their earphones to make a statement.

The earbuds are available in matte black or white and feature big, square housings etched with the Sennheiser logo. The package includes a variety of ear tips, making it reasonably simple to find a comfortable fit — that is, provided the hefty housings don’t get in the way.

To be fair, our ears are on the tiny side, and as a result, we found the housings to be very unpleasant. This will not be the case for everyone, but it is something to consider if your ears are little.

The CX True Wireless charging case hasn’t altered much from the previous generation – it’s still large and therefore a bit difficult to slide into a pocket. The case is charged through a USB-C connection; wireless charging is not included, but we wouldn’t expect it at this price.

An LED light on the charging case outside shows the remaining battery life. It glows green, yellow, or red, depending on the remaining energy in the case.

Audio Performance

Sennheiser’s TrueResponse transducer is housed within each earbud, the firm says, enabling the devices to produce “deep basses, natural mids, and crisp, detailed treble.”

According to our experience with the CX True Wireless, the earbuds are more than capable of living up to those promises. When we listened to Al Green’s Let’s Stay Together, we were impressed by the depth of the bass frequencies, which propelled the music with authority and energy.

Vocals are very clear, with enough detail provided by the synchronized backup vocalists. Overall, the soundstage seems to be very expansive, with enough separation between the various frequencies and a high degree of clarity throughout.

Rechargeable batteries and connection

In comparison to the CX 400BT, the new Sennheiser buds provide a 7-hour boost in battery life, with 9 hours from the earbuds themselves and an additional 18 hours from the charging case.

Even yet, it isn’t class-leading by any means – many wireless earbuds now provide more than 40 hours of playing – and it’s a pity that the case doesn’t have more charging ports given its size.

Additionally, connectivity has been enhanced, with Bluetooth 5.2 compatibility and support for SBC, AAC, and aptX codecs. As a result, you should have no difficulty streaming high-resolution audio files. The earphones were simple to pair with our phone, and we had no unpleasant dropouts throughout our testing.

You can also use each earbud separately if you want; two microphones in each bud should provide quality conversations, and a new Sidetone function makes it easier to hear your own voice during calls. This is customizable through an in-app slider that allows you to choose how much of your own speech is audible.

2) Realme Buds Wireless Bluetooth 5.0, Deep Bass with Mic

While Realme’s focus in 2018 was on smartphones, the Chinese firm has expanded its reach into the accessories market in 2019. Realme’s initial earbuds were Rs. 499 Realme Buds, which were followed by the newly released Realme Buds 2, which retail for Rs. 599. After launching the Realme Buds 2, the business has now launched the Realme Buds Wireless, the brand’s first set of wireless earbuds.

Realme Buds Wireless, priced at Rs. 1,799, continue to compete with Xiaomi, which just released the Mi Neckband Bluetooth Headphones in India. Although somewhat more costly, this model has DJ Alan Walker-tuned sound and 12-hour battery life. Is the Realme Buds Wireless a worthy successor to the Realme Buds? We discover this in our evaluation.


Our experiences with wireless earbuds costing fewer Rs. 2,000 have been generally negative, and we’ve come to accept that excellent wireless devices cost at least Rs. 5,000. The Realme Buds Wireless is a welcome addition to the budget category, providing an excellent value for money mix of style and sound quality. Additionally, lovers of electronic music will be pleased to learn that the Realme Buds Wireless have been adjusted using input from famous DJ Alan Walker, and the sound does really sound tailored to this genre.

We evaluated the wireless earbuds using both the SBC and AAC Bluetooth codecs on a OnePlus 7 Pro (Review) and an iPad mini 2019. We listened to songs streaming through Spotify and YouTube Music, as well as our own high-resolution library.

We instantly noted that the soundstage was much broader and more detailed than what we’re accustomed to hearing from goods in this price range while listening to Take Five by the Dave Brubeck Quartet. While some of the percussion instruments sounded crisp and clear, the deeper parts in the centre of the track — particularly the double-bass — were a little softer and less distinct than we’d have wanted. Overall, we felt the sound to be detailed and rich.

We then played Zombies On Your Lawn, the upbeat theme music from the famous mobile game Plants Vs. Zombies. As with the analog Realme Buds, the Realme Buds Wireless is clearly skewed towards the low end, as shown by the powerful bass in the heavily synthesized sections of this electronic tune. While the bass was not nearly as tight as the Realme Buds 2, we were pleased with the assault and drive for a wireless headphone.

Following that, we were treated to some Indian pop through an Unplugged performance of Amar Arshi’s Kala Chasma. Apart from some mild aggressiveness in the bottom end, we appreciated the track’s inoffensive mids and highs, as shown by the track’s familiar voices. The Realme Buds Wireless’s sound has been adjusted for comfort and near-universal appeal, and it adheres to that brief. We received about as much detail and clarity as we could expect from a set of wireless earbuds for under Rs. 2,000.

Additionally, we tested the Realme Buds Wireless as a hands-free headset for voice calls, with mixed results. In other instances, we discovered that the voices on the other end were too quiet, and our callers reported too much background noise – a crow cawing approximately 20 feet away sounded as if it were coming directly from next to us to the person on the other end. Other times, no problems were reported, indicating that call quality is highly reliant on your surroundings and perhaps the strength of your cellular connection.

Design and Specifications

True wireless earbuds are gaining popularity, and Realme may very well enter that market in the future months. However, for the time being, the firm has opted for an inexpensive version of wireless headphones – neckband-style earbuds. The headset has a stretchy neckband with metal modules at the ends, small wires that connect to the earphones, and the earbuds themselves, which are made of plastic. Our evaluation unit’s yellow-and-black colour scheme was very appealing. The design is straightforward, and the build quality is acceptable. The gadget weighs just 30g and is pleasant to wear and use for extended periods of time.

The Realme Buds Wireless, like previous Realme earbuds, uses magnets in each earpiece. While the magnetic clamps on the wired versions have no function other than to hold the two earbuds together, they act as the power switch on the Realme Buds Wireless. Separating the buds powers the headset on, while reconnecting them powers it off; since there is no power button on the headset, this is the only method to manage power.

This sounds nice in principle, however, the earbuds separated quickly when put in a purse or pocket due to the weak magnets. This would switch on the earbuds and link them to our connected smartphone automatically, which was inconvenient. Without our knowledge, calls would be redirected away from the smartphone’s earpiece, the battery would drain, and the phone would be unable to automatically connect to other devices such as a Bluetooth vehicle music system.

When not in use, we discovered that it was preferable to keep the earbuds on a table or around our neck, which was clearly not always handy. Perhaps a more compact storage case would have been beneficial, but the Realme Buds Wireless does not have one. / expert evaluations.

Experts Opinion

While more costly earbuds such as the OnePlus Bullets Wireless 2 and 1More Stylish Dual Dynamic Driver provide much superior sound quality, the Realme Buds Wireless performs well at Rs. 1,799. This is a product worth considering simply because it has everything you need at such a reasonable price.

This headset is nicely constructed, has a respectable battery life, and is very pleasant to use. The one major issue we encountered was the magnetic power switch, which often resulted in the earbuds automatically turning on at inconvenient moments. Apart from that, the Realme Buds Wireless is a set of earbuds that perform precisely as advertised — no more, no less — with unflinching constancy, and we like them for it.
