Finding 1½-inch gauges that actually stay in your ears without slipping out overnight or feeling like they are about to drop is surprisingly hard. The double flare (the wider front and back with a narrower middle that holds the plug in) needs to be just right. Too shallow and you are fishing them off your pillow in the morning; too wide and they will not go in at all. This guide lines up the six most reliable 38mm (1½-inch) options, from obsidian stone plugs that feel substantial to lightweight stainless steel tunnels and organic wood saddles, so you can match the fit to your lobe thickness and daily routine.
I’m Min Islam — the founder and writer behind Trending Car. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The right pair of 1 1/2 inch gauges for ears depends on how your lobes behave. Thick lobes need a deeper saddle (the wearable middle section); active lifestyles need a secure lock; and new stretches need smooth, gentle materials.
Our Picks at a Glance
How To Choose The Best 1 1/2 Inch Gauges For Ears
The ideal pair at 38mm balances three things: saddle depth, material weight, and how your own lobes react to each. Here is what to weigh before you click add to cart.
Double Flare Saddle Depth — The Real Fit Factor
A double-flare plug (a plug with a wider front and back and a narrower middle) uses that middle section (the saddle) to grip your lobe. If the saddle is too shallow, the plug will not grip, and it will fall out during sleep or movement. If the saddle is too deep, your ear may not accept the flare without irritation. For 38mm, look for a saddle that is at least 10mm deep — anything less and buyers report frequent slips.
Material Weight — What Your Lobes Can Carry All Day
Natural stone like black obsidian at 38mm feels heavy and substantial — many owners describe it as solid and enjoy the gentle stretch. Stainless steel is lighter than stone but still has a noticeable presence. Wood and acrylic are the lightest options. They are great for long wear, but they can feel insubstantial if you prefer a bit of heft. Your lobes will tell you after a few hours which weight is comfortable.
Size Consistency — The 37mm vs 38mm Reality
Not every 38mm plug measures exactly 38mm across the wearable area (the part inside your ear). Some run a hair small at around 37mm, while others match up perfectly. If your lobes are snug at 38mm, a slightly smaller plug may fall out. If your lobes have extra room, a true-to-size 38mm might feel tight. Owners consistently suggest ordering up one size if you are between sizes or if the reviews mention a sizing run that runs small.

In‑Depth Reviews
1. Pierced Owl – Natural Black Obsidian Stone Double Flared Plug Gauges
Our pick — over 4.5★ from 600+ verified ratings; the strongest balance of quality and price.
The obsidian stone plug stays put through your workday because over 600 owners say the quality and fit are better than other options here. It is the one buyers trust most.
You get a heavy, polished feel that many owners say is exactly what they want from stone gauges. The stone feels smooth, the finish is even, and the weight is substantial without being uncomfortable. Reviewers who wear them for long shifts and physical labor report they stay snug and do not pop out — rare for double-flare stone plugs at this size. The fit beats the Sono Wood plugs (which run small) because the wearable area on these measures closer to 38mm.
That said, obsidian is a natural stone. It can crack if you drop it on a hard surface — one owner said it “cracked in half when dropped on marble,” so treat them with care. A few owners with very thick lobes mention the saddle (the middle section) feels shallow, which can cause slipping overnight at the largest sizes. For most people, though, the fit is spot-on and the matte-black look is a classic staple.
What wins people over
- Quality is the most-praised aspect — 30 owners call it out directly
- Heavy and cold to the touch, which stone fans love
- Stays in place during work and sleep for most wearers
Worth knowing
- Obsidian is brittle — dropping it on tile or marble can crack it
- Saddle runs shallow for very thick lobes; may fall out overnight
A worthy everyday staple: If you want a heavy stone plug with a classic matte-black finish that stays put, this is the pick. Thicker lobes that need a deeper saddle make the PVD Steel Tunnels the better bet instead.
2. Pierced Owl PVD Coated 316L Stainless Steel Double Flared Tunnels
You stay active and sleep without worry because these 316L stainless steel tunnels are nearly weightless yet the coating resists chipping for over a year, according to owners.
At 38mm, a heavy stone plug can fatigue your lobe over a full day. These solve that with a near-weightless feel that owners with thicker lobes especially appreciate. The PVD coating (physical vapor deposition — a process where metal bonds to the surface at the molecular level) creates a deep, uniform black. One owner notes “durable black coating, no chipping after nearly a year.” The double-flare design holds securely without O-rings (small rubber bands some plugs use), and the smooth edges make insertion easy.
The trade-off is the same many steel tunnels share: the saddle width is generous to accommodate thicker lobes, so they can protrude slightly from the front of your ear. A handful of owners say the flare is slightly thinner than other plugs they have used. If your lobes are on the thinner side, you may need to adjust them occasionally during the day.
Built for action: Owners who sleep active or work physical jobs say these rarely fall out, and the coating holds up far better than painted tunnels. The 316L surgical-grade steel is a strong choice for sensitive ears — less risk of irritation than cheaper alloys.
The honest limit: If your lobes are thin, the slightly wider saddle may push the tunnel forward more than you like. A few owners found the fit less secure than their previous plugs. This is the one to grab if the Obsidian plugs feel too heavy or its shallow saddle worries you.
Confident pick for active wear: Nearly weightless, stays black, body-safe steel. Thin lobes that cause protrusion mean the Acrylic Plugs (with a slimmer saddle) may fit flatter instead.
3. 1 PAIR (2pcs) ACRYLIC PLUGS Double Flare Gauges Solid Saddle Thin Ear Flesh Tunnels 1039
Quality surprises owners for the price, but the front flare (the wider part that holds it in from the outside) can be too large to insert — a gamble your lobes need to handle.
Acrylic plugs at 38mm are rare, and this pair stands out for the right reasons. They are lightweight, have a smooth finish that some owners say looks like glass, and the double-flare design works well on most pairs. The quality is the most-praised feature here, with ten owners calling it out. They feel comfortable for all-day wear and come in a simple solid design.
The biggest variable is the flare size. A handful of customers note that the front flare is too large to insert easily — one said “the flare is way too big to even get into my stretched ears” — while others found the black version thicker and more secure than the clear version. If you are between sizes or your lobes are on the tighter side, the flare may be a hurdle. For lobes that are well-stretched and accustomed to acrylic, these are a fantastic value.
What works
- Quality is the top praise — 10 owners call it impressive for the price
- Lightweight and smooth; looks like glass to some wearers
What to watch
- Flare size varies — some pairs are very difficult to insert
- Black and clear versions differ in thickness; clear runs thinner
Value play, not for tight lobes: Budget-friendly acrylic that looks surprisingly good. If your lobes are snug at 38mm, the variable flare could be a dealbreaker — the Steel Tunnels offer a more consistent insertion every time.
4. Mystic Metals Body Jewelry Opalite Stone Teardrop Plugs
Teardrop opalite catches light like a gem — 65 owners praise the look — but at 38mm the weight can pull your lobe down and the small flares may not hold it in.
Opalite stone has a translucent, milky glow that shifts colors in different light. Owners mention seeing yellow, red, blue, and purple reflections, which makes these stand out from any other plug in this lineup. The teardrop shape is comfortable because the narrow top avoids putting pressure on the lobe, and the smooth curves make insertion easy. The quality is consistent, and the appearance is the most-praised feature by a wide margin.
At 38mm, the stone weight becomes a factor. Several owners note these are heavy enough that the ear can feel weighed down. The flares (the wider parts that hold the plug in) are not large enough to always keep it secure — one owner reported them falling out four times in a single day. If your lobes are well-stretched and used to stone weight, they should hold fine. For newer stretches or thinner lobes, the combo of weight and small flares may cause slippage.
The big win
- Appearance is the #1 praise — 65 owners highlight the beautiful color shifts
- Comfortable teardrop shape with soft, rounded edges
- Secure fit for many; 38 owners praise the fit
The caution
- Stone weight at 38mm can cause lobes to feel pulled down
- Flares are small — some shoppers say plugs falling out during the day
Best for visual impact — if you can handle the weight: The most beautiful stone glow in the roundup. For a heavy stone that stays put more reliably, the Obsidian Plugs offer larger flares and a more secure lock.
Understanding the Specs
Double Flare vs Saddle Fit
A double-flare plug (a plug with a wider front and back and a narrower middle) uses that middle section, called the saddle, to sit inside your lobe. A saddle-fit plug is a specific type of double flare where the wearable area is shaped like a shallow curved saddle rather than straight. The key number is the saddle depth (how wide that middle section is). A deeper saddle of 10mm or more grips thicker lobes better. A shallow saddle under 8mm can cause plugs to fall out, especially overnight.
Material Density and Lobe Fatigue
Stone (like obsidian and opalite) is the heaviest material at 38mm. It provides a satisfying stretch but can fatigue your lobe over a full day if you are not used to it. Stainless steel sits in the middle: lighter than stone but still has noticeable heft. Wood and acrylic are the lightest — you may forget you are wearing them, but they also provide less stretch sensation. If you are new to 38mm, starting with a lighter material like steel or wood can help your lobes adjust before moving to stone.
