For your consideration, a bunch of inexpensive but high quality IEMs. I carefully selected and enjoyed every one of these of the past few years.

Prices are PayPal G&S and include fees and shipping from California. All prices are OBO.

• Tangzu x HBB Xuan NV. Like new, all packaging and accessories included. The box corners got a little banged up in shipping. Tested for 1 hour, and they overlap with other IEMs I already have. Warm, analogue, natural timbre, and very pretty. $75
• KZ AS24 with tuning switches. Like new. Very detailed with wide sound stage. $85.
• KZ BA10. Good working condition, esthetically challenged. The connectors aren't as tight as they used to be, but the IEMs don't fall off the cable. All-BA, excellent clarity yet still warm and with good bass. Impossible to find anymore. $60.
• Tripowin Olina. Balanced tuning, beautiful DD timbre, very pretty, wide sound stage. $60.
• Dunu Titan S. Similar to the Olina with a little more bass. $65.
• KZ ZSX Terminator and KZ ZSN Pro. VG. $30 together.
