Aluminum Mini Bluetooth Transmitter with 3.5mm Male Jack for TV/ MP3/ PC/ PS4, Wireless Sender and Adapter Works with Bluetooth Headphone and Speaker

Works just as described. Pretty simple to pair with Bluetooth headsets or speakers. Decent battery life. Several hours, but I haven’t continuously used them in one sitting to find out exact length of time. They charge fairly quickly and are able to be charged while being used simultaneously. I would recommend these

Item connects ok, with a little patience, and sound quality is good. I had picked it up to listen to movies on TV without disturbing my wife, but the delay processing through bluetooth introduced a significant disconnect between audio and video. Should work great for music or audio only apps.

This devise works well but there are some little problems. I think it needs to be adjusted for distortion. When fully charged there is output overdrive and it sounds really distorted. As time goes by and the battery goes down (approximately 30 min) the sound does start to clear up. You just have to be a little patient. Another little problem is that it seems to lose bluetooth connection. I use the Airfrex with my ipod and some Bose earpods. When I run I noticed that the sound sometime bounces from left to right then slowly stabilizes. They need to improve the bluetooth connection. Works Ok but they still need to get the bugs out.

Pairing the device was a little confusing but it all worked out.

As others have said, it does not properly pair with a set of buds, in my case LG TONE Free Bluetooth earbuds. I have contacted Airfrex support, but so far no response. I'll give it a few more days and if still nothing will return as defective. UPDATE: Reached out to the company twice, and not a peep in response, so returned to Amazon.

Worked great

I never thought to ensure my daughter's Nintendo Switch Lite was Bluetooth compatible because in today's tech world I assume everything handheld is. She could have used a wired pair of headphones but she'd just got a cool, and expensive, wireless set for her birthday, so couldn't see the point of having to go buy another pair just for her Switch. The Bluetooth connector that is designed for the Switch with its matching colors connects via the charging port, so you constantly have to remove it. My 8yo would have lost it in a day. This little device was exactly what we needed. It's small and plugs into the headphone jack on her Switch, the Bluetooth pairing was quick and easy, and we haven't had any issues. She is only 8 so I can't really comment on the sound quality, but she hasn't ever complained.

Pairs well, works as described. Easy to use. Quality materials and workmanship. Decent battery life and was ready go to immediately after unboxing. After being fully charged and sitting for two days, no loss of battery power. Would have given five stars but the LED indicator is almost impossible to see in the light and there is some latency when transmitting from our new 4K smart TV. Otherwise, great product. Update: Returned this item due to a faulty battery. Stopped holding a charge and would not recharge after almost a month.

Works well with my ipod classic and connecting to my jbl blue tooth speaker. Sound is good.

Easy to use,charge,pair all straight forward.
