- BioElectronics: BioElectronics manufactures wearable, drug-free electrotherapy and PEMF devices for pain management and post-surgical recovery. It targets overlapping patient segments with Zynex's TENS units and chronic pain use cases.
- Breg: Breg designs and distributes orthopedic bracing, cold therapy, and pain management products sold through physicians and DME channels. Its product mix directly overlaps Zynex's bracing & traction and hot/cold compression lines for post-surgical and sports medicine recovery.
- Enovis (DJO): Enovis owns the Chattanooga and Compex brands, which are direct competitors to Zynex in TENS/EMS electrotherapy, hot/cold therapy, and orthopedic bracing. Both companies serve physical therapy clinics, physicians, and direct-to-patient channels for pain management and rehabilitation.
- Performance Health / Compass Health: Performance Health distributes TENS units, hot/cold therapy, and orthopedic braces to physical therapists, chiropractors, and consumers. Its product catalog substantially overlaps Zynex's electrotherapy, hot/cold, and bracing lines.
Broad incumbents
- Masimo: Masimo is a global leader in patient monitoring and pulse oximetry technology, overlapping with the patient monitoring portfolio Zynex acquired via Kestrel Labs. As a large incumbent, Masimo competes for hospital and clinical monitoring contracts.

Emerging players
- iReliev: iReliev sells consumer and clinical TENS/EMS units and accessories through direct-to-consumer channels. It competes with Zynex's TENS device business in the home-use pain management segment, though Zynex's prescription-driven model is differentiated.
- Neurometrix: Neurometrix develops wearable neurostimulation devices (e.g., Quell) for chronic pain, overlapping with Zynex's electrotherapy pain management positioning. Both companies target non-opioid, non-invasive pain relief but Neurometrix focuses on neurostimulation rather than TENS.
