Pros
Pro Good sound quality with true wireless convenience at a low price
The D900 Mini is a great value option if you are in the market for true wireless earbuds/in-ears. The sound is on the neutral side with good clarity with good wireless signal stability, but at a price that is noticeably lower than other options.
Pro Flat sound signature with good clarity
Instead of being bass heavy or having harsh treble, these have more of a flat sound signature, with none of the frequencies boosted. This helps make the sound come off as more natural and accurate, though some might consider this as quite unexciting.
Pro Will stay snug in the ears
The eartips feature ear hooks which help keep these in place when used. These will not fall off easily despite the true wireless design.
Pro Signal stability is very good
Weak signal integrity is a problem with a lot of true wireless headphones, but the D900 Mini's signal is noticeably better, even in environments where there are a lot of interfering wireless connections.
Pro Can be charged on the go
The carrying case doubles as a charger. From a full charge, this accessory can provide 4 to 6 full charges to the earbuds.
Pro Fun sounding with deep and punchy bass, smooth and full mids as well as good detail from the highs
The bass is the highlight of the sound signature. It goes deep and has very good punch too, yet at the same time stays fairly controlled. The mids are present and quite smooth, though not too forward.
The highs do not stand out as amazing, though the level of detail is fairly good.
Overall, a very good sounding pair of in-ear headphones which bass lovers will find to be quite enjoyable.
Pro Cable feels reliable
The headphone cable feels high quality and does not seem like it would break easily. They are also fairly flexible so they should not be too prone to tangles. The strain relief on the connection points of the cable to the earpiece keeps it from detaching easily when yanked.
Pro Fit and isolation can be customized
The CX 300 II come with 3 sets of ear tips in small, medium and large sizes. These are easily interchangeable so you will have some options when it comes to fitting these headphones.
Cons
Con Relatively poor battery life
Playback time from a full charge is around 2 hours. This is an hour shorter than the battery life of most true wireless earbuds.
Con Microphonics can be distracting
If you wear these in-ears while walking around, the movement of the cable can be clearly heard in the earpiece (called microphonics), which can be quite distracting.
Con No in-line controls or mic
You will have to pull out your phone when answering calls or changing music tracks when using these in-ears.
