Against 10 recent comparable asking prices, the typical used market centers at US$26, with the middle half running from US$20 to US$44. At US$21, this is just above the bargain cutoff but still clearly below median—a good, sensible buy rather than an ambitious ask.
The LES-705iR is a practical portable infrared speaker: useful for classrooms, presentations, tours, and other situations where a listener needs clear voice reinforcement without a full PA setup. Its appeal is convenience and intelligibility more than hi-fi refinement, and the included AC adapter makes it ready to use. Before paying, confirm that the infrared receiver function, speaker output, controls, battery operation if fitted, and adapter all work; compatibility with the intended transmitter also matters. At this price, though, a working example offers worthwhile utility and little financial risk.

Lightspeed Technologies, founded in 1990 in Tualatin, Oregon, has built its heritage on enhancing educational environments through innovative audio solutions. Over three decades, the company has focused exclusively on classroom audio systems, prioritizing clear communication between teachers and students in K-12 settings worldwide. This American-rooted brand emerged to address the challenges of noisy learning spaces, evolving from early infrared and FM systems to integrated tools that support inclusive instruction.
The product lineup centers on instructional audio hardware tailored for schools, including speakers, microphones like REDCAT and REDMIKE, infrared receivers, public address systems, media connectors, chargers, infrared sensors, and connecting cables. These components deliver crystal-clear, low-volume sound for whole-group and small-group teaching, while integrating with life-safety and building communication systems. Unlike consumer hi-fi gear such as amplifiers, turntables, DACs, headphones, or high-end cables, Lightspeed's offerings emphasize practical, durable solutions for everyday classroom use.
In the market, Lightspeed holds a strong reputation as a leader in edtech audio, not in the high-end hi-fi or audiophile niche but as a reliable provider of award-winning systems that boost engagement, teacher vocal health, and accessibility for all students. Positioned for educational institutions rather than home enthusiasts or vintage collectors, it occupies a specialized, mid-tier segment focused on functionality and safety over luxury sound reproduction. If seeking consumer hi-fi, this brand does not align.
