Setting up the Turtle Beach Stealth 400 was a very straight forward procedure. Simply plug in the USB dongle to the back of the console, then hook the included TosLink optical cable from the console to the dongle. You can use any USB port on the console, but the one at the back is best so you don’t have a wire trailing around to the front of the console. You will need to charge the headset before use, but out of the box I found it only took an hour to get my headset up to 100% charge. You can use any available USB port on your console to charge your headset, or those found on your TV, PC or a special mains adaptor. Setting it up for use on a mobile device is even easier, just hook up the 3.5mm cable and you’re ready to use the Stealth 400 like any normal set of headphones.
Initial testing of the drivers was impressive. The drivers maxed out at 101 dBa, which is more than enough to give you a thumping headache after moderate use, or good news for those who like to have their headsets cranked up extremely loud. With the headset on my ears I found that 72 dBA of the noise leaked at 100% volume over a range of 3ft, which is pretty poor and 65 dBa at 50% volume. This means that who ever is sitting next to you and maybe whoever is setting next to them, will be listening to what you’re listening to; whether they like it or not.
Sound quality on the Stealth 400 is pretty decent, the headset is certainly powerful and crystal clear at all times. However, it does lack a little in the bass department, it sounds good while gaming, but doesn’t excite me when watching movies or listening to music. The gaming performance, especially so the in-game chat audio and microphone performance are superb. The headset sounds like it’s tuned towards eSports and pro gaming in general, where a focus on higher frequencies is often preferred as it makes it easier to pick out your enemies footsteps in fps titles.
