SND-Ray Bone conduction sunglasses: a polarized Hifi hero

SND Ray bone conduction sunglasses frames and colors

Today we want to highlight a new kind of sunglasses which might be the first sunglasses which we could categorize as a successful competitor or even replacement of Zungle. If you recall our previous articles you will also recall that two years ago we discussed and reviewed the Zungle Viper bone conduction sunglasses. Overall, they looked and worked quite well but looking back the previous months we must admit Zungle support, when having questions or when confronted with issues, is for sure as it should be. Besides, the sound was ok but no more than ok and there was a lot of sound leakage at higher volumes. So, we are curious about the performance of a new player on the sunglasses bone conduction market; namely SND-RAY. They call themselves the “best HIFI bone conduction sunglasses” on the market at Indiegogo… but critical and skeptical as we are, we first want to take them to the test before confirming this PR quote.

But who and what is SND-Ray and can the team behind this brand be trusted? Well, as far as we can go and know… it looks like this brand can be trusted. The company behind, SND-Ray Labs Inc., is a registered company located in Cheyenne of which all details can be found on the Internet. A big pro we believe because we have seen others in the past on Indiegogo and Kickstarter.

The story behind the design and development of SND-Ray goes back to a mountain walk. A nice story with an adventurous touch which immediately grabs your attention. Telling your story you will create trust with your audience, but of course there is no trust without consistency and a product which triggers your senses. Wait and see…

Sunglasses with that extra touch

The SND-Ray sunglasses are not your regular type of sunglasses. Yes, they have polarized lenses and yes they have UV-blocking characteristics and yes they even have the famous and popular Rayban Wayfarer design… but that’s where the similarities stop and the differences start. These sunglasses are so much more. The SND-Ray is equipped with Bluetooth 5.0 connectivity to ensure a smooth connectivity with other Bluetooth devices like your smartphone. They have an integrated microphone and 4 bone conduction speakers (read transducers allowing you to not only listen to music but also to pick up calls and to talk to the person on the other side of the line.  The 4 bone conduction speakers will create a so-called “authentic and outstanding 360° sound”!

Next in the line of specifications is their water resistance. SND-Ray Labs Inc. claims their product will have an IP55 water resistance. IP55 means it is protected against dust ingress that could be harmful for the normal operation of the product but is not fully dust tight. It is protected against solid objects and water jets projected by a nozzle. So, all in all sweat and rain will have no influence on the functionality of your glasses but don’t use them in a shower or for swimming.

We are also happy to ready a single charge of 30 minutes allows you to listen up to 6 hours to music. A big improvement compared to other bone conduction sunglasses and even the classic bone conduction headphones. The device is charged via a standard Mini-USB port. One day we hope bone conduction newbees or even classic brands will introduce wireless charging though.

One other major differences with other glasses is the chance to order prescription lenses. A nice extra for sure!

So all in all, the specifications and characteristics sound very nice theoretically and we hope they will also sound nice in practice!

SND Ray vs Zungle Viper

As stated before, in September 2018 we have also reviewed the Zungle Viper and the Zungle Panther. Although we still like the looks of these glasses and gave them an overall good rating for their sound, we did determine a few areas of improvement. Moreover, the past year we have received a few messages of people who had encountered issues when trying to contact Zungle for after sale support. With regard to the areas of improvement we would have liked a more dynamic sound and less sound leakage at higher volumes. These were the two most important remarks. Looking at the characteristics of the SND-Ray these ‘obstacles’ to buy a Zungle might have been tackled. The SND-Ray bone conduction sunglasses promise a more dynamic and 360° sound experience thanks to 4 built-in bone conduction transducers while Zungle Viper only had two of these vibration speakers. Besides the manufacturers also promise no sound leakage… Especially regarding this aspect we are curious. We have some good experiences with headphones like the AfterShokz Aeropex and the AfterShokz Trekz Air so fingers crossed the SND-Ray will be the first bone conduction sunglasses to reach the same level of sound leakage quality.

If we look at the SND-Ray vs Zungle Viper aspect we also notice several other enhancements and specifications which the Zungle doesn’t have. First of all, they are lighter. Secondly, they are IP55 water resistant and have a playback up to 6 hours (vs 4 hours for the Zungle). Finally, the SND-Ray has polarized, scratch-resistant lenses (the Zungle has standard UV-blocking lenses).

We have now contacted SND-Ray Lab Inc. to deliver us one of their bone conduction sunglasses in order to provide an honest review of their product, probably beginning of 2021.

      Too bad to hear you had a bad experience with them but thanks for informing us. So far I had the best bone conduction sunglasses experience with Zungle but I have also heard some bad experiences with the support. So far these sunglasses are working fine for me though.
