So I went ahead and purchased this
XY-01 Wireless Bluetooth 4.1 Smart EarPhone (Yellow/Black)
Photo from Lazada. Item linked.
It comes in several color variants (all black, white/red, white/green) and is undrbanded, though the packaging says it's made by "BestGot". According to the package, it's capable of 5h talk time, with an effective 10m range, and bluetooth 4.1 support.
It was scheduled to arrive by August 22, and arrived this morning. Despite being slightly late, I don't mind as I had requested delivery to the office, and the hours don't lend itself to weekend delivery.
Here are some photos of what the package looked like and what came in the box.
Yet-unopened. Looks nice. Better than what they used on the site.
They provided 2 identical manuals. For no apparent reason.
The package came with 2 sets of identical manuals, a short usb cable for charging, 2 extra earbuds, the clip and 2, um, whatever you call those claw-like things that help it stay on your ear when you're active. However since it's really meant to sit deeply into your ear anyway, it feels like those were just a nice bonus.
The build is a bit plasticky, slightly less impressive than my previous one (which was all white). The volume up button seems sit a little deeper than the volume down. Doesn't change the functionality any though.
The clip doesn't have any rotating pieces so it's slightly less comfortable than what I previously had but I think it just needs getting used to.
I tried using them straight out of the box but there wasn't any charge to speak of so I charged them for 30 minutes before giving it another go.
Listened to a bit of music on it and tried using it to record audio on the sound recorder. The gave good results for the former, and pretty lousy results for the latter. I tried calling myself to test it on a call, but not hearing myself talking to myself on the other phone kinda defeats the purpose. I did have to make an actual call later in the day after a full charge and letting it stand by for a bit as well. There was a lot of static but the other party could hear me OK.
Aside from the static on the call, and the slightly questionable build quality, there's only one minor gripe I have about the bluetooth headset. And it's this:
On the phone, when you pair, it doesn't appear as a standard bluetooth headset. It appears as an "input device" ~ as a keyboard, which it is most definitely not. The only other instance I've seen that happen was with a bluetooth camera trigger I purchased a year or two ago and that was most likely also made in China.
To use it like a usual headset, and to be able to use the phone's onscreen keyboard, I just unticked the "input device" option.
For Php 366 (roughly 8.14 USD), you really shouldn't expect much. But honestly, it's a bargain. Audio for music's pretty good, despite the static on the call. The color combination's pretty nice. Won't really know how long this will last so will keep my finger's crossed.
Bottom line, pretty good bargain. If you need a bluetooth headset and don't have a big budget and are willing to put up with a bit of static, go for it!
