Although discontinued, this joint effort between the well-regarded custom in-ear monitor and earphone manufacturer Ultimate Ears and Logitech should be highly considered. Also because it is discontinued it can be bought for less than half the original price.
Pro You can enjoy the details of the audio you are listening to because of these headphones' clarity
These headphones are pretty good in terms of clarity. The high frequencies are balanced really well in such a way that they bring out a lot of details from the music without sounding harsh or abrasive.
Pro You can share audio with other wired earphones or headphones using the included audio splitter
It is possible for UE6000 users to listen to music and share it with other earphones or headphones. The UE6000 comes with an audio splitter which you connect to the 3.5mm headphone jack of the source device. This then splits the signal to two 3.5mm ports which you can connect the UE6000 and another pair of earphones or headphones to.
