Why I Decided to Buy Wireless Bluetooth Headphones
Recently, I've been frequenting the gym where the music is so loud that it’s practically deafening. Since I couldn't stand the noise, I always bring my own headphones. Until now, I’ve been using an older model of Sony SBH50 Bluetooth headset, which isn’t bad in terms of sound quality. However, its design, which separates the receiver from the headphones, along with the short cable, makes it quite inconvenient. Plus, once I wear compression clothing, the receiver tends to get squished uncomfortably, and the cable often gets pulled. I’ve also tried using my trusty old wired headset, but after one particularly intense session where it got tangled with a cleaning robot, it met its untimely demise. This experience pushed me to finally invest in a completely wireless Bluetooth headset. I didn’t want to spend too much, but I also didn’t want to risk buying something cheap that might break easily, especially since the gym can be a risky place for electronics (don’t ask me how I know). In the end, I just picked one randomly without overthinking it. It seemed like a decent option at the time.

Product Review: Selbel (Dellable) D900S Wireless Bluetooth Headset
Appearance Gallery
The packaging for this headset is quite sleek. On the front, you’ll find the product image prominently displayed.

The back of the package provides some basic information about the product.

Opening the box reveals all the contents neatly arranged.

Inside, you’ll find the headset itself, along with silicone ear tips in different sizes, and a small black silicone strap designed to keep the earpieces from falling out during workouts.

The charging case is magnetically sealed, ensuring it stays shut unless intentionally opened. When charging the headphones, the indicator lights flash blue.

Once the case is closed, it also charges the headphones. You'll notice the indicator light on the headset flashing red.

When charging begins, the indicator turns red and automatically shuts off once fully charged.
Experience and Feelings
First Impressions:
The build quality of the charging case is okay, though I did notice some dust inside when I opened it. The hinges could be smoother, and there’s a slight roughness to the edges. The charging port on the side works fine.
The headset itself is bulkier than expected, with noticeable looseness in the buttons, which wobble slightly. The silicone ear tips feel comfortable, and they’re elastic enough to fit snugly, though not perfectly stable. They won’t fall out easily, but they don’t stay put either.
One downside is that the silicone ear tips aren’t fixed at a specific angle, so adjusting them correctly is key. If not positioned properly, you might experience sound leakage or a sensation of them slipping off.
The charging case includes a battery that automatically starts charging the headphones upon placement, which is super convenient.
Usage Experience:
Operating the headset is straightforward—left ear controls calls, while the right ear handles music playback. The indicator lights are clear, showing red or blue depending on the status.
Sound Quality:
Treble: While not exceptional, it’s acceptable.
Midrange: Vocals come through well, with decent clarity.
Bass: The bass response is somewhat muddled.
Soundstage: To be honest, it’s lacking depth.
In Summary:
The main advantage is convenience—no wires, easy charging, and the ability to use it hands-free. Comfort-wise, it’s average, and the sound quality is decent for the price. The build quality is a bit rough around the edges, but only time will tell if it holds up. For now, it’s great for watching dramas or listening to music while working out. It’s lightweight and cordless, making it ideal for active use.
Overall, it’s a solid choice for those looking for a budget-friendly wireless headset, but it’s not perfect.
