Handheld Scientific Bt500 Bluetooth Adapter

I tried a very fancy and highly scientific lens cleaner from Edmund Scientific, but it left streaks. In fact, I thought maybe the coating had been removed in places. As a last ditch effort, I bought this and sprayed it on and it turned out that the coating is fine and the lens is now clean.

this USB-BT500 works great with the intended use i had planned for it. Along with other uses i had not considered. Nice Device.

You may want to consider a Bluetooth adapter for your headphones rather than this. They are harder to loose and more convenient.

Very useful adapter for laptop w/o Bluetooth. Easy to install, and works great.

I have a number of various iPhone holders for tripods and handheld stabilizers. This one takes the cake! I have 3 MeFoto tripods that I use so this is an ideal pairing. It allows for iPhone rotation without using special adapters which is very handy. the nice part is that it fits perfectly into the base on the tripod without having to use the normally removable plate. However, I have an adapter to rotate the camera through 360 degrees which I attach this unit to and use the removable plate in between. Very happy with my purchases and would highly recommend this adapter.

Are you destitutely poor? Need professional audio for your handheld camcorder? Buy this instead of an XLR adapter. Plugs directly into the microphone jack on your camcorder and the end of an XLR cable or a shotgun mic.

After researching and deciding between this lens, the Sport version (2x the price and 2lbs heavier!), and the Tamron 150-600 G2, I went with the Sigma Contemporary. I purchased the Sigma MC-11 adapter for Sony E Mount as well. Optics are outstanding, as advertised. Between the Sigma and Sony A7iii stabilization, I can shoot handheld at 600mm. Autofocus does hunt a bit on the MC-11 adapter - I have not yet compared its operation on my Canon 5Dmkii. As noted in other reviews, this lens is heavy. Absolutely an arm workout if shooting handheld, especially at 600mm (full extension). For low light or evening work, a tripod is required. For me, it was worth it to get the reach I've been missing.

Inexpensive, and great for use by kids. I bought this handheld mic adapter when I was asked to chaperone my grandson's 5th grade class at a 3-day educational retreat/camp. The interview handle worked great, enabling the kids to play reporter on camera. And the audio that resulted was great, too, far better than I would have gotten with an on-camera mic -- especially in noisy environments, like a couple of kids on camera with hundreds more talking and making noise immediately around us.

Having a bluetooth adapter on my PC has made things so much easier. Amazing price. Works wonderful.

Purchased a Bluetooth adapter just to see what all the fuss was about ..Sent a few files to my computer.. Could have done this through Email :-) Only con i found is when I paired this with my Bluetooth headphones, my wifi connection would become choppy..
