Is the CrossBeats Hertz worth considering? If you want budget earbuds that list active noise cancellation, a 40ms gaming mode and Bluetooth 5.4 together, it is worth a look, but expect some gaps. Its Amazon.in listing does not give an ANC strength in decibels, does not explain the “Sleep Buds” label in its title, and states no water-resistance rating. The variant covered here is the Black model sold under ASIN B0G6D8R6XM.
CrossBeats, a brand with its listed address in Bengaluru, describes the Hertz as having adaptive ANC, AI ENC microphones for calls, 10mm titanium drivers, up to 60 hours of total playtime with ANC switched off, SnapCharge fast charging and Hall-switch auto-pairing when the case opens. That mix should appeal to students, commuters and casual mobile gamers who want ANC on paper without paying for a premium pair.
About this article: we have not used or tested the CrossBeats Hertz. Everything below comes from the specifications on the Amazon.in listing, captured on 17 October 2026 while it was in stock. CrossBeats’ official product page could not be accessed on that date, and we found no independent review we could verify, so every claim is attributed to the listing.
Quick verdict
- Best for: budget buyers who want ANC, low-latency gaming and a newer Bluetooth version in one pair
- Skip if: you need a stated ANC depth, a water-resistance rating for workouts, or proven battery figures with ANC on
- Key strengths (listing claims): adaptive ANC, AI ENC mics, 40ms gaming mode, Bluetooth 5.4, up to 60 hours with ANC off, SnapCharge, Hall-switch auto-pairing
- Key limitations: no ANC dB figure, no playtime figure with ANC on, no SnapCharge numbers, no IP rating, no explanation of the “Sleep Buds” claim

How strong is the ANC? The listing does not say
The Amazon.in listing describes “Intelligent TWC ANC and AI Adaptive Noise Cancellation” and lists the noise control type as Adaptive Noise Cancellation. Adaptive ANC usually means the CrossBeats Hertz adjust the level of cancellation to your surroundings, rather than running at one fixed level all the time. In theory, that saves battery in quiet rooms and works harder in traffic.
What the listing does not give is a decibel figure. Many rivals state one, such as 32dB or 35dB, which at least lets you compare claims. Without it, you cannot judge how much low-frequency noise, like a bus engine or an aircraft hum, the Hertz will remove. Budget ANC in general works best on steady, low rumbles and less well on voices and sudden sounds, so set your expectations accordingly.
The listing also does not mention a transparency or ambient mode, which some competitors include so you can hear announcements without removing the CrossBeats Hertz.
How to check the ANC yourself during the return window
- Play nothing and switch ANC on and off in a steady noise, such as a fan or an AC unit. A clear drop in hum means the ANC is working
- Try every ear tip size first, because a poor seal weakens ANC more than anything else
- Test once in real traffic or on public transport, where you will actually use it
- Note battery drain with ANC on over a typical day, because the listing’s 60-hour figure is with ANC off
Battery life and SnapCharge
The listing headline is up to 60 hours of total listening time, but the same bullet clarifies that the 60 hours applies when ANC is turned off. Playtime with ANC on is not stated, and ANC always uses extra power, so if you plan to keep it on during commutes, expect less than 60 hours. The listing also does not split the figure between the CrossBeats Hertz and the case.
SnapCharge is CrossBeats’ fast-charging feature. The listing says a 10-minute top-up gives “hours of playback” but does not say how many. Treat it as a useful convenience rather than a specific promise.
Gaming mode, Bluetooth 5.4 and pairing
The listing claims a dedicated gaming mode that brings audio delay down to 40ms. That is lower than the 45ms or 50ms claimed on some rival listings, though a few rivals claim 33ms to 35ms. Low latency matters in mobile shooters where footsteps and gunfire need to line up with the screen. Gaming modes can sometimes reduce connection range or stability, so switch it off when you are just listening to music.
The title states Bluetooth 5.4. Newer Bluetooth versions mainly bring efficiency and connection-handling improvements, but the experience still depends on your phone. The listing does not mention codecs beyond the basics, an app, multipoint or Google Fast Pair, so do not assume those features.
CrossBeats also lists an “Enhanced Hall Switch” for auto-pairing. A Hall sensor detects when the case lid opens, so the CrossBeats Hertz can power on and reconnect to the last device without you pressing anything. It is a small convenience, but a nice one for daily use.
Sound: 10mm titanium drivers
According to the listing, the Hertz uses 10mm titanium drivers with a 32-ohm impedance, and CrossBeats promises “deep lows and clear highs” with a “3D-like audio stage”. Titanium coatings are used to make driver diaphragms stiffer, which can help with clarity. Note that 10mm is smaller than the 12.4mm or 13mm drivers several rivals list. Driver size is not the whole story, but bass-focused listeners may want to compare. The sound description is marketing language, and we have no independent measurements to cite.
What about the “Sleep Buds” label?
The product title calls the Hertz “Sleep Buds”, but none of the feature bullets explain what makes them suitable for sleeping, such as a low-profile shape, a sleep mode or a timer. If you want earbuds to wear lying on your side, do not buy on the title alone. Check the product images for how far the buds stick out of the ear, and use the return window to test comfort.
Durability, warranty and service
The Amazon.in listing does not state an IP rating, so the Hertz should not be relied on for sweat-heavy workouts or rain. The listed weight is 48 g, which is likely the earbuds and case together or the package, since the listing does not specify.
The listing states a 1-year warranty from the purchase date with service support across India, and asks buyers to register the product to activate warranty benefits. Do that soon after delivery and keep the invoice. The country of origin is listed as China, with CrossBeats’ Bengaluru address given as the manufacturer contact.
Who should buy it, and who should skip it
| Buy the Hertz if you | Skip it if you |
|---|---|
| Want ANC on paper at a budget level | Need a stated ANC strength to compare |
| Play mobile games and value a 40ms claim | Work out hard or train outdoors, since no IP rating is listed |
| Like auto-pairing when the case opens | Need multipoint or an app with EQ |
| Mostly listen with ANC off and want long playtime | Plan to run ANC all day and need a confirmed figure for that |

Frequently asked questions
Does the CrossBeats Hertz have real ANC?
The Amazon.in listing says it has adaptive active noise cancellation, plus AI ENC microphones for calls. It does not state how many decibels of noise it cancels, so its strength cannot be compared with rivals from the listing alone.
What is the CrossBeats Hertz battery life?
The listing claims up to 60 hours of total playtime with ANC turned off. Playtime with ANC on is not given.
Is the CrossBeats Hertz good for gaming?
It claims a gaming mode with up to 40ms latency, which is lower than several budget rivals’ claims, such as 45ms and 50ms.
Is the CrossBeats Hertz water resistant?
The listing does not state an IP rating, so avoid exposing it to sweat-heavy workouts or rain.
Does it support Bluetooth 5.4?
Yes, according to the listing title, and it works with older Bluetooth phones too.
Conclusion
The CrossBeats Hertz packs a strong feature list on paper: adaptive ANC, AI ENC calling, 40ms gaming mode, Bluetooth 5.4, Hall-switch pairing and up to 60 hours with ANC off. Its listing leaves out the numbers that would let you compare it properly, especially ANC depth, ANC-on battery life and water resistance. Buy it if the feature mix suits you and you can test it within the return window.
