We have a review of Soundpeats D3 from our official tech reviewer Josh.
The packaging for the Soundpeats D3 has a stylish yet quite minimal design on the packaging. The packaging itself is nothing special but is good quality for the price. Inside the box is another smaller box containing the D3 and the accessories that come with it. I found the micro USB cable which comes pre-packaged in the box with the D3 to be too short and found it awkward to plug in as it is so short. Also in the box with the D3 was two other ear tips for the D3 which are for people who need slightly larger ear tips or slightly smaller ear tips as the D3 comes with a medium sized ear tip already on the D3. The included manual was very informative and included diagrams of how to use and operate the D3.
The D3 was very simple to pair to my phone as to pair it all you need to do is hold down the multimedia button for around 5 seconds and then you can pair the D3 to your device. After it is paired I tested the sound quality of the D3 and found that it has good but muddy bass and reasonable mids and highs. The call quality on the D3 was reasonably good as it sounded a little bit tinny but you could still clearly hear the person on the other end. The microphone built into the D3 sounds quite tinny but you can still clearly hear what I was saying from the receiving end of the call.
The multimedia button on the D3 was quite useful as with one tap you can pause or play whatever you are listening to or if you are in a call you can tap the button once to hang up. Tapping the button twice calls the person you have contacted most recently. I found this quite simple to use and I am quite surprised with the responsiveness of it. The battery life on the D3 after intensive use is only three hours, which is the same as Soundpeats claimed the talk time on the D3 were. This meant I had to charge it in the middle of the day after using it. It takes about 3 hours to charge with the micro USB cable included. This just meant that the time I spent using the D3 was slightly reduced as they needed constant charging. The short battery life of the D3 is consequence of it being very small, light and portable. This raised a concern that it could be lost very easily as the D3 is very small.
Overall the Soundpeats D3 are a reasonable quality Bluetooth headset for a fairly low price and as it is such a low price. I feel some corners have been cut quality wise in some areas but are overall good value.
