• Avantalk Avantree Sky Infinity — biggest strength: Two pairs of active noise-cancelling earbuds plus a plug-in transmitter, so two people can share the same in-flight movie or AUX audio in sync.
• Avantalk Avantree Sky Infinity — biggest trade-off: It is a tech product with a charging routine, touch controls, a 3-hour charge time and a 24-month warranty to keep track of — it asks more of you than a pair of earmuffs ever will.
• PETSEAR Dog Ear Muffs — biggest strength: A simple, passive design rated up to 29 dB of noise reduction, sized by head circumference and ear distance, aimed squarely at dogs in loud environments.
• PETSEAR Dog Ear Muffs — biggest trade-off: It does nothing until your dog tolerates wearing it, and the fit has to be right or the protection is wasted.
• Who each is for: Avantalk for the traveller or audio sharer; PETSEAR for the dog owner dealing with fireworks, thunder or loud household noise.
This is a travel audio kit, not just a pair of earbuds. The box includes two pairs of Infinity NC earbuds, four extra pairs of earbud tips, a Relay transmitter, and a short USB-C charging cable. The idea is straightforward: one pair goes in your ears, the other sits in the compact charging case, and you swap whenever you need to. That two-pair setup is the whole point of the product, and it is what separates it from a normal set of ANC buds. On a long-haul flight or a packed day of meetings, the swap-and-keep-going approach means you are never stuck waiting on a charge.
The second half of the story is the transmitter. It plugs into an airplane seat screen or any AUX output, and both earbuds pair with that single transmitter — so you and a friend watch the same film with the same audio, in sync, instead of splitting one set of wired headphones. The earbuds also connect individually over Bluetooth to a phone, tablet or laptop, so the kit keeps working after you land. Bluetooth 5.3 with aptX Adaptive, aptX HD, aptX Low Latency, aptX and SBC covers the common bases: low latency for video, better fidelity where the source supports it, and a fallback codec when it doesn't. Range is listed at up to 33ft / 10m, which is generous for moving around a cabin or a room.
Buy it if you fly long routes, want two people sharing one audio source, or you like the idea of a spare pair always charged and ready. Skip it if you simply want one pair of earbuds for the commute, or you dislike touch controls and managing charge cycles — a plain set of ANC buds will be simpler and cheaper for that job.
PETSEAR Dog Ear Muffs: Who It's For
This one is a single-purpose product, and that is its strength. It is a passive noise-reduction earmuff for dogs and cats, built around an ABS outer shell and soft PU foam ear cushions, with gentle ear ring pads and an upgraded Velcro adjustment strap. The headline figure is up to 29 dB of noise reduction — meaningful attenuation for a dog, without any electronics, batteries or app to manage.
The design detail that matters most is sizing. PETSEAR offers the muffs across XXXS, XXS, XS, S, M and L, and the guidance is explicit: measure head circumference and ear distance and pick from the size chart. The S size reviewed here is listed for a head circumference of roughly 12.5 to 16 inches. That is not marketing padding — get the size wrong and the seal breaks, the dog fights the fit, and the noise reduction drops. The Velcro strap exists precisely so you can fine-tune it once you have the right shell size.
The intended use cases are the ones dog owners actually lose sleep over: fireworks, thunderstorms, air travel, and loud household noise like vacuums, power tools or a crowded event. PETSEAR recommends it for environments with continuous noise exposure at 85 dB and above. It also ships with step-by-step fitting instructions and training tips, which tells you the brand expects an adjustment period rather than instant acceptance. Colour here is pink, the pattern is cartoon, and the muffs are described as imported, unisex-adult in department terms. Weight is listed at 8 ounces for the package.
Buy it if your dog is stressed by predictable loud events and you are willing to spend a few sessions training them into wearing the muffs. Skip it if your dog will not tolerate anything on its head, or if you are looking for something to reduce noise for a person — this is not that product.
• Best for sharing audio with another person → Avantalk Avantree Sky Infinity. The transmitter plus two earbud pairs is designed for exactly that.
• Best for a dog in a loud environment → PETSEAR Dog Ear Muffs. 29 dB of passive reduction in a shell built for animals.
• Best for long-haul flights → Avantalk Avantree Sky Infinity. ANC, aptX Adaptive and the swap-and-charge case all point at air travel.
• Best for fireworks and thunder → PETSEAR Dog Ear Muffs. This is the scenario the size range and fitting guide are aimed at.
• Best for everyday phone, tablet and laptop use → Avantalk Avantree Sky Infinity. Each earbud pairs over Bluetooth on its own, with a 33ft / 10m range.
• Best for zero-maintenance ownership → PETSEAR Dog Ear Muffs. No battery, no firmware, no charging cable — just an ABS shell, PU cushions and a strap.
• Best for forward-looking features → Avantalk Avantree Sky Infinity. Auracast LE Audio lets you join public broadcasts without pairing.
• Best for fitting flexibility → PETSEAR Dog Ear Muffs. Six sizes plus a Velcro strap, versus one-size earbuds with four spare tip pairs.
These two products do not compete — they solve different problems, and I would not talk a traveller out of the Avantree kit or a worried dog owner out of the PETSEAR muffs. If I had to pick one for myself, I would buy the Avantalk Avantree Sky Infinity, because the combination of active noise cancelling, two swappable earbud pairs and a plug-in transmitter covers long flights, shared viewing and everyday Bluetooth listening in one box, and the 24-month warranty with chat, email, phone and video support backs it up. The PETSEAR muffs are the better buy only if the person you are protecting has four legs and a fear of thunder. Check the current price on Amazon before you commit, since that is the one thing that could tip a close call either way.
FAQ
Measure your dog's head circumference and the distance between the ears, then match those numbers to the size chart rather than guessing. The S size is listed for roughly 12.5 to 16 inches of head circumference, and the Velcro strap lets you fine-tune the fit from there.
The product is described as noise-reduction earmuffs for dogs and cats, and the recommended environment is continuous noise at 85 dB and above. The sizing chart is your guide — a very small dog or a cat will likely need one of the smaller shells.
Yes. Both earbuds pair with the single Relay transmitter, so two people hear the same source in sync. That works with airplane seat screens and any other AUX output, and each earbud can also connect separately to a phone, tablet or laptop over Bluetooth.
