Ultra-Thin Fit for Side Sleepers
The In-790 earbuds weigh 0.7 grams each and sit flat inside the ear canal so nothing presses against the pillow. Bluetooth 5.3 keeps the link stable while you move during the night. They are built for people who find regular buds painful after an hour. Buyers who need active noise cancellation for travel or a transparency mode for awareness should look elsewhere.
Steady Output Through the Night
A single charge runs for 4 hours and the case holds enough power for 24 hours total, so the buds keep playing white noise or podcasts until morning. Adaptive noise cancellation reduces steady background hum without draining the cell faster. The 13 mm dynamic drivers hold consistent bass and mid levels at low volumes. Listeners who want high-SPL music sessions or critical monitoring will not get the headroom they need.
IPX4 Shell and Touch Controls
The IPX4 rating shrugs off sweat, rain and a quick rinse, making the buds practical for early-morning runs as well as bedtime. Type-C charging refills the case in about 1 hour and the LED display shows remaining capacity at a glance. Touch surfaces handle play, pause and calls without a physical button to dig into the ear. Users who prefer a wired fallback or a larger charging case with extra capacity will not find those options here.

Questions about this item
Do the 13 mm drivers produce noticeable warmth during an all-night session?
Each bud weighs 0.7 g and draws little power, so heat buildup is minimal even after several hours of continuous use.
What charging port must my power source provide for the case?
The case charges via USB Type-C, so a Type-C cable and a standard 5 V USB supply are required.
Will Bluetooth 5.3 maintain a stable link if my laptop only has an older Bluetooth adapter?
Bluetooth 5.3 is backward compatible, so the earbuds will connect to older adapters, though range and latency may be reduced.
