As these are still pretty big drivers for a mobile device, the LS-20s do come with a powered amplifier and this is to help reduce the strain on the mobile phone and the battery. It means that when in device mode, the drivers can still deliver the punchy bass required for the mobile device at volume levels it does not achieve in passive mode. Don’t worry though about listening time, these will last a good 8+ hours of constant use before you’ll need to recharge. Even in passive mode these work quite well, they just lose a little bit of their kick when without the additional amplifier but completely useable in a pinch away from electricity. Like the LS-30, there is also an equalizer built into the headset but only have normal(balanced) mode or bass boost. You can’t fault them for not adding as much as the more expensive bigger brother but one of two settings is a little slim pickings.
Connect them up to any mobile phone with a 3.5mm jack and you are good to go (sorry iPhone 7 users) and they’ll also work with any headphone jack on a PC, gaming console such as the PlayStation 4 or Xbox One (if you have the newer controller or the 3.5mm adapter). It is a shame that there is not other connectivity for the 20’s as these would do really well if they included a Bluetooth connection. Seen as LucidSound have gone through the effort to make them amplified and powered it would not cost much more to get that included.
Overall, for £80 the LucidSound LS-20’s are a decent portable gaming headset which has multiple uses. They are a sexy alternative to your usual gaming headset and a good combatant compared to more well known music headphones. They definitely look the part of well-build, high-end headphones but to get the most of the 40mm drivers you will need to make sure they are full charged. One thing missing from them is Bluetooth, for the £80 I don’t think it would of went amiss to add it in. It is also a shame that the built in equalizer is not more varied just to give the audio a bit more distinction depending on what you are using them for.
