From the above specs, the noteworthy specs are the IPX7 rating, making it not just water/sweat resistant, but actually waterproof. Theoretically, we should be able to submerge the earbuds in water that is less than 1 meter and leave in for up to 30 minutes, with no negative effect on the earbuds. Standard test la, however, I don't recommend you do that to this or any of your electronic devices though. It also promises Deep Bass, 8 hours of playtime per earbuds charge, and a massive 56 hours in total from subsequent Case charges. These excellent numbers are due to each earbud packing a 60mAH battery, and the charge/carry case packs a whopping 800mAH battery. The case capacity ensures that both earbuds can be fully charged at least 6 times, if not 7 times just off the case alone. I easily got between 48 hours and the claimed 56 hours of playtime. In my books, that's more than enough to power through a week or even 2 weeks (lighter usage) before needing to charge the case back up. Speaking of charging times, the earbuds take about 1 and a half hours, while the case plugged in, takes around 2 and a half hours for a full charge.
The transmission range is listed as the standard 10 meters; however, my tests show it's capable of almost double that range. I placed my phone in a closed-off room and walked off. Music continued to play smoothly until I got to around 17 meters or 56 feet, before stopping abruptly. Walking back within range initiates a swift reconnect and all's back to normal. I'd say that's excellent. The exterior of the case is made from plastic, but it's of the good kind. Matte black that I love as it is significantly less prone to fingerprint oils, dirt, and smudges. We have four LEDs on the front that indicate current case battery levels or when the case or earbuds within are charging. And on the back, we have a USB Type-C port for charging. No wireless charging supported here. The hinge on the inside is also made of plastic but appears to have some form of metal running through it, to provide durability. Neither the hinge nor case flex when pressed hard. It's just a solid block with an even weight to it (earbuds inside, else feels a tad bottom-heavy) and it opens and closes with a satisfying snap. Thus far, the only issue at this point is the size doesn't allow for one-handed operation. However, this is expected due to the shape and size of the battery and the earbuds themselves. I recommend watching the video to see exactly what I'm referencing here.. I've included timestamps for easier navigating.
From the video, we can see that the placement of right and earbuds are reversed. Initially, this confused me (didn't get to explain this part properly in the video before shooting), but then I realized that it's to facilitate the right hand reaching over to the left side of the case, lifting the earbuds, and sliding the hook around the right ear. Repeating the same for the left ear. That's all fine and dandy until you want to place them back in the case. One would need to consciously remember to go right to left, & left to right. So.. yeah.. tad bit of a hassle there. Hopefully the S2??? would sort out that design "kink".
Pairing this with a new device is easy. Just open the box with the earbuds in it and the pairing mode is automatically triggered. Enable Bluetooth on the source device and tap on the newly found HappyAudio S1 profile ID. I was pleased to find that Mono and stereo modes are supported by this same single profile ID. Once paired, the red and white flashes stop and you can simply take one or both earbuds out of the case to enjoy. The Multifunction button or MFB is touch-sensitive and supports the following functions;
You can also switch between 2 ongoing calls by long-pressing the MFB for 1.5 seconds on either earbud. This HappyAudio S1 is the first TWS earphone I've reviewed or seen with this particular feature... NICE!! The S1 also sports earbuds status Voice Prompts such as Connected/Disconnected, Power On/Off, TWS Connected, and Battery Low.
Calling performance is quite satisfactory when I used it with various VOIP or Internet calls such as Telegram, Skype, WhatsApp, and regular GSM or Mobile calling. I am yet to experience a single unexpectedly dropped Bluetooth connection either. The audio playback quality is quite good too. As I mentioned earlier, the premium 12mm dynamic drivers deliver professionally-tuned immersive crystal-clear sound with a silky treble, smooth mids, and really punchy bass at any volume. No Active Noise Cancellation or ANC feature here. However, I have to point out that the passive noise-canceling could be much much better IMO. But then, some might even argue that making you aware of external sounds is...actually...a desirable feature. One, outdoor exercise enthusiasts or runners might prefer. As it enables you to keep listening to detailed musical sound, and still be aware of happenings in your surroundings.
I test various media streaming apps off Microsoft's Windows, Mac OS X, Android, and iOS devices. Apps such as Netflix, YouTube, Spotify, and Tidal. I'm happy to announce that all audio-video playback was satisfactory... I.e, no noticeable lag or sync issues. The same is said for mobile gaming. I was able to enjoy hours of online multiplayer games without AV sync or lag issues. I plan to upload a separate video showing this and a couple of other latency tests. So kindly like & subscribe to my YouTube channel for more updates. Turn on the notifications as well.. Danke..
Admittedly, these are not the most stylish. However, if you are on a limited budget, willing to embrace such a form factor (that actually works as advertised), and want impressive all-week battery life? These are a great value pair of affordable yet supremely comfortable and well-built TWS earphones.\
