Which is better for watching TV with a partner?

The Avantree Duet. It includes two headphones and a dock that charges both, so two people get independent volume. The RS 275 ships with one headphone.

Which has better battery life?

The Sennheiser RS 275, at up to 50 hours versus up to 20 hours for the Duet. The Duet's dock makes recharging easier, though.

Which is better for hearing loss?

Both target it. The Duet adds volume boost up to 20% louder and a Clear Voice mode. The RS 275 uses personal hearing profiles and speech clarity.

Is the Duet worth the extra $50?

Yes if two people watch or you want a charging dock and 30ms low latency. If you watch alone and want Bluetooth, the RS 275 costs less at $189.98 at Walmart.

Can I use either with a phone or tablet?

The RS 275 supports Bluetooth, so yes. The Duet is 2.4GHz RF for TVs only, with optical and AUX inputs.

Which keeps audio in sync better?

The Duet publishes 30ms latency, which is low enough to avoid noticeable lag. Sennheiser does not list a latency figure for the RS 275.
