Outdoor Tech Turtle Shell 4.0 Waterproof Bluetooth Speaker

$69.95

Built to withstand the elements, the Turtle Shell 4.0 is ready to accompany you on any adventure. Its durable construction ensures it can handle the bumps, drops, and splashes that come with any lifestyle.

A Loud Waterproof Bluetooth Speaker

Now in its fourth edition, the Turtle Shell produces heavier base and clearer sound without distortion setting it apart from its predecessor. It plays louder, for longer, from further away. We've even improved the waterproofing, so you can literally take this waterproof Bluetooth speaker into the water with you. It floats. No lie. Would we lie? No.

Design is Important

The Turtle Shell 4.0 saves lives with 360-degree sound from an IPX7 rated polygonal housing that wouldn't look out of place in an interior design magazine - an avant-garde appearance that belies its rugged, dust, shock, and waterproof capabilities. A built-in microphone lets you take and make calls and ask your digital assistant to find out just how deep is the deepest lake in the world (it's Lake Baikal, for the record, at 5,314 feet) while you float off in tubular, tunular bliss.

Huge Battery

The upgraded battery capacity of the Turtle Shell 4.0 gives you an outstanding 18 hours of playful playtime, with the ability to act as a portable power bank for your phone or music player as well. If your source isn't Bluetooth-ready, you want to save some battery time, or wires are just your thing, that's cool - the included 3.5-to-3.5mm cable lets you keep listening... but you won't be able to use the impressive 50-foot free-range-chicken mobility that makes the Turtle Shell 4.0 so liberating.

True Wireless Pairing

Now that you're free, it's time to get loud. And the Turtle Shell 4.0 is a wireless speaker that can get even louder thanks to its true wireless daisy-chain function - linking up to as many as 50 - yeah you heard that right, 50 other Turtle Shell 4.0's up to 15 feet away, to create a wall of well-designed, tougher-than-coffin-nails, louder-than-loud sound that extends a whopping 45 feet away from your source. It's just what they do.

Welcome to your resurrection, kid. Never thought a turtle would save you, did you?

Shipping policy

Where we ship and shipping charges

Shipping availability depends on the product, supplier, and delivery address. Enter your address at checkout to see the available shipping options and final shipping charge before payment. If no shipping option is offered for your address, we cannot ship that combination of items to that destination. A shipping zone does not mean every product is available in every location.

Fulfillment through our partners

Apex Technica works with fulfillment partners, including suppliers through Shopify Collective, who ship products directly to customers. An order containing products from different suppliers may ship in separate packages. Shipping charges may be combined across packages; review the total at checkout.

Processing and delivery estimates

Order handling generally takes 3–5 business days before dispatch, but varies by supplier and product. Business days are Monday through Friday, excluding holidays. Carrier transit time is additional to handling time. Contact hello@apextechnica.com before ordering if you need an item-specific dispatch estimate or delivery by a particular date. For Collective products, available shipping rates and carrier transit estimates are calculated at checkout. Carrier transit estimates describe time in transit after dispatch, not a guaranteed order-to-delivery date. Weekends, holidays, carrier disruptions, and customs processing can affect delivery.

Tracking and separate shipments

We send shipping confirmation and tracking details when they become available from the fulfillment partner. Separate shipments may have different tracking numbers and arrive on different days. Tracking can take time to show the carrier's first scan.

Address changes, delays, and delivery problems

Check your address before placing an order. Contact Apex Technica promptly to request a correction or cancellation; changes may be unavailable once processing begins. If a shipment is delayed, missing, damaged, or incorrect, contact us with your order number so we can investigate with the supplier or carrier. Do not send an item back without return instructions. See our return and refund policy.

Refund policy

Last updated: November 4, 2026

30-day returns

Apex Technica accepts return requests within 30 calendar days after delivery, including returns because you changed your mind. This policy applies to products fulfilled by Apex Technica and by our fulfillment partners, including Shopify Collective suppliers.

Product condition

Items returned because you changed your mind must be unused, in their original packaging, and include all accessories and proof of purchase. This condition requirement does not prevent you from reporting a damaged, defective, or incorrect product.

Fulfillment partners

We work with fulfillment partners to ship some orders. Apex Technica remains your contact for returns and refunds and will coordinate with the partner. The return window and fees in this policy apply regardless of which partner fulfills your order. Do not send products directly to a partner without our return instructions.

How to request a return

Email hello@apextechnica.com within 30 days after delivery with your order number, the item you want to return, and the reason for your request. Include photos if the item arrived damaged, defective, or incorrect. We will provide authorization, the correct return address, and shipping instructions. Returns are made by mail; items from different partners may require separate return shipments. Please retain tracking and proof of shipment.

Return costs

For change-of-mind returns, the customer is responsible for purchasing the return shipping label and paying return shipping. Original shipping charges are not refundable for change-of-mind returns. We do not charge a restocking fee. For damaged, defective, or incorrect items, contact us so we can arrange an appropriate return or other resolution without charging you return shipping.

Refunds and exchanges

After the authorized return is received and inspected, we will notify you of the outcome. Approved refunds are issued to the original payment method within 10 business days after receipt and inspection. Your bank or payment provider may require additional time to post the credit. For exchanges, contact us to arrange a return and a separate new order; replacement availability is not guaranteed.

Damaged, defective, incorrect, or missing items

Contact Apex Technica promptly if your order arrives damaged or incorrect, has a defect, or does not arrive. We will investigate with the fulfillment partner or carrier and explain the available resolution. Manufacturer warranty coverage is separate from this return policy. Nothing in this policy limits rights that cannot be excluded under applicable law.
