The SM-823D Pro is a stethoscope-style headset that hangs under the chin, with memory foam tips, a light alternative to over-ear cups for people who wear glasses or dislike headbands. Its strongest feature for hearing differences is a balance control that sets left and right volume separately. Simolio adds a tone control and a Mono setting it recommends for clearer TV dialogue, plus a MIC mode that amplifies room sound so you can hear a partner without removing the headset. The 2.4GHz transmitter needs no pairing and takes optical, RCA or 3.5 mm input, with an optical bypass for a soundbar. Battery life is up to 14 hours from a replaceable lithium cell. Limits: HDMI ARC only TVs need a converter, Simolio says the model is not recommended for pacemaker users, and its page quotes both 100 ft and 164 ft for range. At $94.99 on sale it was the cheapest option we found.
