Costco has long been known for bulk groceries and budget-friendly food court staples, but its technology aisle has become a quietly important part of the membership value proposition. The retailer regularly rotates in new gadgets, often at prices that undercut standard retail listings, and October 2026 is no exception. This month's arrivals span outdoor audio, fitness-ready headphones, mobile content creation, home security, and smart door access. For shoppers who want to stay on top of the latest gear without paying full specialty-store prices, the current lineup offers several compelling options.

Part of what makes Costco's tech offerings appealing is the combination of competitive pricing and a generous return policy. That reduces the risk of trying a new brand or category. Inventory can vary by warehouse and online availability, so the exact selection may differ, but the following five products represent some of the coolest new tech items reported for October 2026. They range from a floating Bluetooth speaker to a smart lock that uses ultra-wideband technology. Each one targets a different part of everyday life, and each brings a specific set of features that justify a closer look.

Speaqua Barnacle X Waterproof Speaker

The Speaqua Barnacle X Waterproof Speaker arrives as a rugged, portable audio option built for people who spend time outdoors. Priced at $79.99, it is designed to survive splashes, dust, and rough handling. Its IP68 rating means it is certified waterproof and dustproof, a level of protection that goes beyond casual water resistance. The speaker also has a buoyant design, so if it ends up in a pool, lake, or river, it should float rather than sink. That makes it a practical choice for pool parties, camping trips, tailgates, beach days, and fall gatherings where weather and terrain are unpredictable.

Mounting flexibility is another key feature. The Barnacle X can be attached to bikes, boards, backpacks, and other surfaces. It includes a built-in hook, a 1/4-inch threaded mount that fits camera or GoPro-style accessories, and a suction cup for securing it to smooth surfaces. Like most Bluetooth speakers, it can pair with a phone to stream music, podcasts, or audio from other apps. However, it also includes 8GB of onboard storage, which can hold up to 2,000 songs. That onboard memory allows phone-free listening, a useful feature when you want to leave your device behind or keep it protected from water and sand. For shoppers who want a durable speaker that can move from a patio to a trail without worry, the Barnacle X is one of the more versatile new arrivals.

Shokz OpenTri Bone Conduction Sports Headphones

For runners, cyclists, and gym-goers, traditional headphones can create a frustrating trade-off. Over-ear models may feel bulky, while earbuds can slip out during intense movement. The Shokz OpenTri Bone Conduction Sports Headphones, priced at $159.99, take a different approach. Instead of pushing sound directly into the ear canal, bone conduction technology sends vibrations through the small bones in the ear. This keeps the wearer's ears open to ambient sounds, which is an important safety benefit when exercising near traffic, trails, or other people.

The OpenTri model can sync with up to two devices at once, making it easy to switch between a phone, laptop, or tablet. It also includes 32GB of onboard storage, so users can load music and play it directly without a phone. That feature is especially useful in environments where a connection is unavailable or unwanted, such as a swimming pool. According to Shokz, the headphones carry an IP68 rating and are safe to use in water up to 6.5 feet deep for up to two hours. Battery life is rated at nine hours in Bluetooth mode and six hours in MP3 mode. A quick 10-minute recharge can restore about three hours of use, which adds convenience for busy schedules. For athletes who want audio without blocking out the world, the OpenTri is a specialized but appealing option.

Hohem iSteady M7 AI Tracking Smartphone Gimbal

Smartphone cameras have improved dramatically, but handheld footage can still look shaky and unprofessional. The Hohem iSteady M7 AI Tracking Smartphone Gimbal, available for $199.99, is designed to solve that problem. It is essentially a more advanced version of a selfie stick, with motorized stabilization that keeps a phone camera steady during movement. Users can hold it by hand or place it on the ground using its built-in tripod stand. That makes it useful for vlogging, travel videos, live streaming, social media content, and family recordings.

The standout feature is the gimbal's native camera, which does not record video itself but works as an AI tracking sensor. It can lock onto a subject and automatically move the smartphone camera to follow that person or object. This allows a creator to move around while the gimbal keeps the shot framed. The M7 also comes with a detachable touchscreen remote for adjustments while filming, and it can recognize simple gestures as commands. Its pan axis offers infinite 360-degree rotation, so the camera can keep track of a subject regardless of where they walk or turn. For aspiring filmmakers and content creators who want more polished smartphone footage without buying a dedicated camera, the iSteady M7 is a flexible tool.

Wyze Anti-Glare Indoor Window Security Cameras

Home security cameras often face a common problem when they are placed inside a window and pointed outdoors. The glass reflects the interior of the room, creating glare that can ruin the footage. The Wyze Anti-Glare Indoor Window Security Cameras, offered at Costco in a three-pack for $79.99, are designed specifically to address that issue. They attach directly to a window using a special two-way mounting sticker. The sticker goes on the glass, and the camera mounts on the other side with its lens facing through a cutout. This setup prevents reflected glare from appearing in the video.

Each camera records 1080p HD footage and includes features such as two-way audio, color night vision, and AI-powered motion detection. The package also includes 10-foot power cables and cable clips to help keep the installation neat and secure. Because the cameras are controlled through the Wyze smartphone app, users can check live feeds, review alerts, and adjust settings remotely. They are also compatible with smart home platforms including Amazon Alexa and Google Assistant. This design is particularly useful for renters, apartment dwellers, or anyone who wants to monitor a yard, driveway, or entryway without drilling holes in exterior walls. The three-pack pricing makes it easier to cover multiple windows at once.

Aqara Smart Lock U400

The Aqara Smart Lock U400, priced at $259.99, is a home security device that combines convenience with advanced access technology. It is built to use Apple's ultra-wideband technology, which allows it to sync with a paired Apple device such as an iPhone or Apple Watch. When someone approaches the door with a paired device, the lock can automatically disengage. This is especially helpful when carrying groceries, packages, or other heavy items and unable to reach for keys or tap a device manually.

The lock also uses Smart Intent Recognition, a feature designed to unlock only when someone approaches with clear intent. That means it should not trigger simply because a person walks past the door or because someone is using their phone inside the home. Beyond automatic unlocking, the U400 can be engaged or disengaged through several methods: a keypad, guest codes, NFC cards, mobile apps, physical keys, or registered fingerprints. It is powered by a rechargeable battery pack, and two battery packs are included with purchase. For homeowners who want a smart lock that balances fast entry with multiple backup options, the Aqara U400 represents a high-end addition to the October 2026 tech lineup.
