Review on 🎧 SEYOO Earbuds Mini Headphones: Waterproof Sports Earphones with Charging Case and Built-in Mic - Dark by Gabriel Elliott

I decided to try this out on my desktop computer so I can stream to my A/V receiver which I just bought a bluetooth music receiver for. I've tried iPhone 5, HTC One and an older iTouch (not sure which generation but it has bluetooth). From my den to the common room where the receiver is located, everything worked flawlessly. No signal breaks or the like. With this transmitter from the same location, the signal is barely enough, it remains intermittent and very intermittent. I need to add a USB extender (which happened to be on hand) to bring the unit 4 or 5 feet closer, and get the Bluetooth receiver on the A/V receiver as close to the stash as the cables for this one allow allow device. (possibly 2 1/2 to 3 feet). So I would say the range for my copy of this bluetooth transmitter is closer to 20ft than 30ft. With all other devices I tried as above, the range to my music receiver was 30 feet or more. It spans two interior walls, one of which has an entertainment center, so your mileage may vary depending on the environment. The software/driver on the CD that came with this device seems pretty good and allows you to turn off the radio or turn off detection so other bluetooth devices can't detect your computer (for security reasons). No entitlement to supplied software/drivers. Would buy again in the hopes that the next copy I get has a better tuned transmitter or if I just need the 20 foot range.
