Why so complicated? Because while the Switch is Nintendo's first console to offer online voice chat, the system isn't compatible with wireless headphones. That means if you want to play Splatoon 2 from your couch, you're going to need an awfully long cable. The aux cords packed in with the kit are apparently only 1.2 meters (just under 48-inches) long. And because voice chat is handled via a smartphone app, well, everything needs to be in close proximity of each other. Hopefully you don't have an iPhone 7, because, well, that will entail yet another dongle.
The kit is made by Hori and officially licensed, so at least we know it should be decent quality. Nintendo Switch (translated) says that the headset will be released July 21st in Japan to coincide with Splatoon 2 for ¥3480 ($31.25). You'll also be able to dress your Inkling kid up with an in-game version of the headset.
On the surface, this looks like an accessory built specifically for Splatoon 2 in the way that the GameCube controller adapter was built specifically for Super Smash Bros for Wii U. Nintendo's overall plans for voice chat are still ambiguous, so maybe consider this piece of hardware an awkward olive branch.
In January, Nintendo America president Reggie Fils-Aime defended his company's decision to use a smartphone app and headphones for handling voice chat to IGN with the following:
"We want to reinforce the capability to take your experience with you on the go.... The ability to do matchmaking, voice chat through your phone, it's a hell of a lot more convenient than having a gamer headset stuck into your backpack trying to do that. That's why we're doing it the way we are. We see the convenience, we see the ease of delivery. We think it's going to lead to a better experience."
What a difference five months makes. And you thought the amount of dongles and wires needed to connect accessories to a new MacBook was ridiculous.
