AfterShokz Xtrainerz vs Sony NW-WS623: which is better on waterproof?

By  Fields Corrielus 2019-08-29 6815 1

AfterShokz Xtrainerz and Sony NW-WS623 are two waterproof headphones with IP 68. But are they the same in waterproof? Let’s have a look.

Whether you admit it or not, waterproof and dustproof is definitely one of the biggest selling points of all kinds of electronic products.The advertisement that Quan Zhixian put his Samsung mobile phone under the faucet is still fresh in people's memory. Now, whether it is mobile phones or headphones, or other devices, known as "waterproof and dustproof" products are also increasing. 

As many people probably know, there is an index called IP protection level that can measure the waterproof and dustproof performance of a product. IP is followed by two digits, the larger the number, the better the waterproof and dustproof performance. Currently, the highest level of protection is in IP68. The official explanation for this level of protection is that the effect of continuous immersion can be prevented in water with a depth of more than 1 meter, and the exact conditions are specified by the manufacturer for each device. 


Can you see that? the IP protection level is actually a particularly rough measure. IP68 seems to be the most stringent level of protection, but in fact it only sets a "lower limit," and the upper limit is specified entirely by the manufacturer. This means that the same IP68, is likely to be waterproof and different. 

We might as well compare two "swimming headphones" with IP68 protection: one is Sony's WS623. This product is also famous among swimmers. Sony officials say it can stay operational for 30 minutes at a depth of 2 meters with special waterproof earplugs. By IP68 standards, it is fully qualified. But at the same time, you have to see that it actually adds a condition, that is, "when using waterproof earplugs." Without these waterproof earplugs, IP68 would have to be discounted. In fact, as a user of WS623, the waterproof earplugs are at risk of damage or loss.

Another product is the new "Internet celebrity"-AfterShokz Shaoyin's Xtrainerz bone conduction headphones. The headphones are also protected by the IP68, but can last for two hours at a depth of 2 meters, and their waterproof "endurance" is as much as four times that of the WS623! More importantly, it does not need to use any additional accessories, relieving users of a lot of worries.

By comparison, you can see that the same level of protection does not actually mean the same waterproof ability. The level of real waterproof capacity, or to see the manufacturer for the IP68 to do a detailed introduction. It can be said that in terms of waterproofing, Xtrainerz is actually one level higher than WS623, although they all look the same IP68. 

So if WS623 had previously been the only choice for swimmers and hydrophils, the launch of Xtrainerz could have marked the "new king." Stronger waterproof performance, no need to use special accessories, more natural open listening experience, more "senseless" comfortable wear, are higher than the WS623. The only obstacle is that, for most people, AfterShokz Shaoyin is not as well known as Sony Dafa. However, AfterShokz Shaoyin actually has a strong sense of "minority superiority" in the sports crowd, and this time, through the powerful product power of the Xtrainerz product, it is bound to be recommended by swimming and other hydrophilic users. And how do you know that AfterShokz Shaoyin will not be beyond Sony in the future?
