Bluetooth version numbers creep up every year, and most people are not sure whether they matter. The AULA A500 uses Bluetooth 5.4, one of the more recent versions, and it is fair to ask what that changes when you pair it with a phone. The honest answer is: less than the number suggests, but it does give you a modern, efficient link. Here is what Bluetooth 5.4 on a headset means day to day.
Quick Answer
Very little you will hear directly. The AULA A500's Bluetooth 5.4 gives a current, efficient phone link with about 10m of range. The bigger phone perks are its flip-to-mute boom mic, call control on the multi-function button, and an ANC key that can wake your voice assistant. It also connects over a 2.4GHz receiver or a 3.5mm cable, and Evetech sells it for R639.
📱 Will an older phone pair?
Yes. Bluetooth is backwards compatible, so a headset on 5.4 pairs with phones and laptops on older versions. The connection then runs at whatever both devices support. You do not need a new phone to use the A500.
🔊 Does 5.4 improve sound quality?
Not by itself. Sound quality over Bluetooth depends mainly on the audio codec both devices use, the headset's own tuning and the source you are playing. The Bluetooth version is more about how the link is managed: efficiency, stability and connection handling.
In practice, the benefit of a recent version is a modern, well-behaved connection rather than a change you can hear. Treat 5.4 as a sign of up-to-date hardware, not as an audio upgrade.
📞 The phone features that matter more
Answering calls
The multi-function button handles calls, along with power, play and pause, tracks and volume. Answer and end calls without touching your phone.
Voice assistant
According to AULA, the ANC key also wakes your voice assistant, and answers Teams calls on a PC. That puts hands-free control on a button you are already using for noise cancelling.
Flip-to-mute mic
Lowering the concealed boom opens the mic, raising it cuts you off, and it can be angled towards your mouth. On a phone call, that gives you an obvious, physical mute.
💻 Phone and PC together
The A500 can hold its 2.4GHz receiver link and a Bluetooth link at the same time. Pair the receiver with the PC before connecting Bluetooth to your phone, then a one-second press on the multi-function and ANC keys at once moves you between them. That means you do not have to re-pair each time you move from the PC to your phone.
Range around the house
The Bluetooth link is rated at about 10m. Walls, doors and even your own body can shorten that indoors, so keep the phone reasonably close if the audio starts to stutter.
Listening time
The 1000mAh battery gives around 60 hours with noise cancelling running, and about 100 hours with ANC off, according to AULA. Charging over USB-C takes about 3 hours.
