Buzz
Tronsmart Apollo Air + also supports the automatic pause feature. When you take either earbud out, the music will pause automatically and when you put it back on, it will play automatically.
Sound Quality
Tronsmart Apollo Air + relies on 10mm dynamic graphene drivers with 32 ohm impedance. The earbuds are based on the mid-range Qualcomm QCC3046 chip, found in devices like the in vivo TWS Neo. This chipset is quite solid, and apart from the usual SBC and AAC codecs, it also supports aptX and aptX Adaptive.
As a result, we get fairly good and detailed sound. The mid frequencies are best here, and the bass frequencies are also good. But the highest frequencies are weaker. Overall, the sound can be described as clean.
The headphones have better sound than the Realme Buds Air 2 Neo or Air Pro because the mid frequencies are clearer, but I don't compare it to its predecessor. Overall, we have good and relatively detailed sound. There's more than enough volume, using aptX codec on the Google Pixel 2 XL.
Tronsmart Apollo Air + has only three microphones in each earbud – two microphones for noise control and one microphone for voice. Overall, we get quite good and high-quality speech. There's also cVc 8.0 technology once again – a feature of Qualcomm QCC3046.
Active Noise Cancellation and Ambient Sound Mode
As a modern flagship, Tronsmart Apollo Air + is equipped with active noise control system. What does that mean? The main feature of hybrid noise control is the presence of two microphones to pick up ambient noise: outside and inside each earbud. Therefore, noise control is more effective than single-microphone models, as a wider frequency range is blocked.
And indeed, that's the case – ANC in Apollo Air + works more robustly and therefore effectively blocks out external noise better than my personal Realme Buds Air Pro. But as always, the system deals best with low and mid-range noise. According to the manufacturer, ambient noise is reduced by up to 35 dB. Additionally, the ANC mode affects low frequencies when listening to music – they become slightly larger than when noise control is turned on.
The ambient sound mode is set up. Conversely, it slightly increases all external noises, partially offsetting the passive noise reduction ability, and will be useful to use while moving around the city.
Connection Quality and Latency
Thanks to the Qualcomm QCC3046 chip, which supports TrueWireless Stereo Plus technology, among other things. This is also one of the features of Apollo Air +, which allows us to simultaneously connect both earbuds to a smartphone with synchronous signal transmission capability. Additionally, we have the latest version of Bluetooth 5.2.
Therefore, we do not have any specific main headphones and have fast and high-quality connection with smartphones. And I can't say that the connection itself is perfect. Many times it has also happened that a fraction of a second before, the sound only started on one earbud (mostly on the left). It's unclear if this is related to anything, but no rules of this phenomenon can be determined. Additionally, when using only one earbud, sometimes within a few seconds, it can 'fall out' on its own and reconnect automatically.
The latency is hard to perceive. I would even say that when watching movies or videos, it's barely noticeable. At least I also don't perceive any gap between sound and image. But in dynamic games, there is a slight latency and nothing can be done about it.
Battery and Charging
The battery capacity of the Tronsmart Apollo Air + earbuds is 35 mAh each and another 300 mAh in the case. There will be about 5 hours of playback for a single charge, while with the case, this number goes up to 20 hours.
The case allows you to charge the earbuds about four more times, this is also the most common index that will not surprise anyone nowadays. The usage time can be said to be average.
For charging, it can be done via USB Type-C or wirelessly.
Conclusion
Tronsmart Apollo Air Plus certainly has its strengths, such as diverse control mechanism, clear sound supporting aptX codec, as well as good microphones. Unfortunately, its noise cancellation feature is not very outstanding, the latency is still high, and the battery also isn't impressive.
If to give advice, you should buy the regular Apollo Air version. The difference is no aptX codec, no proximity sensor, and no wireless charging but it saves nearly 1 million dong.
