Product review: Wireless Microphone Set, KIMAFUN 2.4G Wireless Headset Microphone and Lavalier Lapel Mics


This microphone works using audio ports on the devices (i.e. it does not use a digital connection). The receiver and transmitter communicate via 2.4G radio signal.  The receiver and transmitter need to pair to each other before use (they do so after both units are turned at the same time after about 2 seconds).

I tried this microphone with three devices: Android phone, Linux laptop, and Linux desktop.  Instruction mention the need to use the splitter in the setup.  For the devices I tried, the mic worked when it was plugged in directly into the phone and laptop, and did not work when I used the Y-splitter.  I am including a recording of playback from the phone as well as the original sound for comparison.  I also tried the microphone on the Webex call that ran on my laptop (Redhat 7 distro). I was told that I sounded fine.  On the third device, I tried, the Linux desktop running Fedora, the microphone did not work, the desktop did not recognize it.  


When I was using the mic on the Webex call, I could not hear anyone unless I unplugged the microphone from the audio port.  It took me a bit of troubleshooting to figure out the issue. It turns out that this is because my laptop does not have a board necessary for this type of use.
 
If you want both the microphone and speaker on the desktop/laptop to work at the same time you need to use use a USB adapter. To use the adapter you need a USB sound card with two 3.5mm sockets. My laptop does not have this sound card, so I connected the mic directly to the headphone jack. In this configuration, the microphone occupies both audio input and audio output, and this means the output (the speakers) do not work. You need an adapter that can separate them.

Both receiver and transmitter have built-on lithium batteries that are charged via USB. The receiver and transmitter take 4 hours to fully charge, and they can run for 8 hours recording.

This set includes two microphones (headset and lavalier mics), transmitter and receiver that plug into an audio port, dual USB cable so you can charge both transmitter and receiver from one USB charging port, Y splitter, foams, and 6.35 adapter if you want to use this microphone with a PA system.

This microphone is best for doing video voice-overs and other applications when you only need the microphone and not microphone and speakers at the same time like Webex and Zoom video conferences.

Product review: EearFun Over Eear Bluetooth Headphones




EarFun headphones work both as wired and Bluetooth wireless headphones. I thought the sound was equally good in both modes, and I could make the loudness as loud in both modes. I normally listen to the headphone with the sound down about halfway. Otherwise, it is too loud for me.   The Bluetooth range is very good with the phone resting on the desk. I can walk away about 20 feet until the sound starts breaking up occasionally.

The headset is extremely comfortable, it fits over my ears. It can be adjusted in so many ways, and it feels very comfortable for both my husband and me, even though our heads are shaped very differently. 

Both the headphones and the headband are well padded.  The headphone cups have a lot of degrees of freedom: they both twist around and pivot up and down.  The headband can flex easily to fit heads of different sizes. The pads are made out of soft leather. While being super comfortable, sound isolation is not 100%. The comfort is comparable to my husband's Bose headset, but not the sound isolation in Bose is better (but at a much higher price).

It is fairly lightweight; it weighs 9.5 oz.  Some days at work I wear it all day long. If the headphones are heavy, my head/neck gets tired from the extra weight, but these have been working just fine.

To test the sound, I listened to several pieces of music I use to test headphones. Using the same piece of music allows me to compare different headphones in "apples to apples" comparison. As a stress test for the base, I use Bach's Toccata and Fugue in D minor. There are several sections in Toccata which some headphones cannot handle they crackle or sound muddy.  EarFun headphones did very well. The sound was crisp, and the base was impressive.

I had no problem pairing the headphones with my mobile devices for listening to music. To pair I needed to push down the on/off button until the light began flicking red/blue. Then the phone detected "EarFun" and connected.  It also worked well with my laptop's Bluetooth.
I am using the phone in an office environment to cover up the noises from loud neighbors so sometimes I wear these headphones all day long and they feel comfortable, and the charge lasts all day long.

When the headphones are charging the small light on the right headphone is red. When it is fully charged, it turns green.  Overall, they do an excellent job, and I have been very pleased.
