How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of earbuds that protects your hearing on a loud job site while still streaming aptX HD audio all shift, choose HomeSpot Work Headphones; if you need a tiny transmitter that turns an airplane seat's 3.5mm jack into a Bluetooth feed for two sets of headphones at once, choose Avantree Relay & SoundJet.
• HomeSpot Work Headphones — biggest strength: a 27dB NRR, OSHA-compliant design with aptX HD audio, Bluetooth 5.4 and up to 24 hours of playback in a neckband that stays put.
• HomeSpot Work Headphones — biggest trade-off: passive noise cancellation only, so the isolation depends on the triple-flange tips sealing properly, and the neckband look is strictly functional.
• Avantree Relay & SoundJet — biggest strength: a pocket-sized transmitter that pairs two Bluetooth headphones to one 3.5mm source, with aptX Adaptive and HD audio and up to 25 hours of play time.
• Avantree Relay & SoundJet — biggest trade-off: it is not a headphone at all — it only works with a 3.5mm AUX output and Avantree states it is not compatible with phones, car stereos or hearing aids.
• Who each pick is for: HomeSpot for warehouse, workshop and power-tool users who want protection and music in one device; Avantree for flyers and gym users who want to share a single audio source wirelessly.
The HomeSpot Work Headphones sit in a narrow but genuinely useful category: hearing protection that also plays audio. The headline number is the 27dB NRR, and the design is described as OSHA-compliant for reducing exposure to machinery, power tools and other loud equipment. That puts it in warehouse and industrial territory rather than casual listening. The soft triple-flange silicone tips are the mechanism here — they form a noise-isolating seal, and because the isolation is passive, the fit is what does the work. If the seal is right, you get protection; if it isn't, you get a pair of earbuds with average blocking.
On the audio side, the specs are more serious than the safety-first framing suggests. Bluetooth 5.4 with up to 100 ft (30 m) of range in open areas means you can walk a large floor without dropping the connection, and the drivers are dynamic with 16 ohm impedance. aptX HD support on compatible devices is the detail worth noting — it's a high-resolution codec, so if your phone or player supports it, you're getting better-than-baseline wireless audio rather than the thin sound you'd expect from work gear. The CVC microphone helps cut surrounding noise on calls, and controls are physical buttons for volume, tracks and calls — the right call in a gloved, noisy environment where touch controls are a liability.
Battery is listed at up to 24 hours of playback (average life 20 hours) with a 2-hour charge, which covers long shifts without mid-day charging. The lightweight neckband keeps the earbuds around your neck so you're not losing one on a warehouse floor.
Who should buy it: anyone who spends the day around loud equipment and wants one device for protection, calls and music — warehouse staff, tradespeople, machine operators, lawn and engine work at home. Who should skip it: commuters who want active noise cancellation, people who dislike in-ear seals or neckbands, and anyone whose source device doesn't support aptX HD and who mainly wants the codec benefit.
The Avantree Relay & SoundJet is a different animal entirely — it's an airplane Bluetooth adapter, not a headphone. You plug it into a 3.5mm AUX jack, and it streams that audio to your Bluetooth headphones. Avantree lists compatibility with AirPods, Bose and all Bluetooth headphones, and explicitly notes it is not compatible with phones, car stereos or hearing aids. That last point matters: this is a source-side transmitter, so it only makes sense where there's a 3.5mm output to feed it — in-flight entertainment being the obvious case, with gym equipment as a secondary one.
The chipset is the selling point. Qualcomm's premium silicon powers aptX Adaptive and aptX HD, running over Bluetooth 5.3 for stability, and Avantree leans on its 20 years of wireless experience here. If your headphones support those codecs, the adapter is designed to deliver higher-fidelity, lower-latency audio than plain SBC — which is exactly what you want when you're watching a movie and lip-sync drift would ruin it.
The genuinely distinctive feature is dual headphone support. Two Bluetooth headphones can connect at once with synced playback, which is the whole reason to carry one of these on a flight with a travel companion. Onboard buttons handle pairing and volume, LED indicators show connection status, and play time is rated up to 25 hours — comfortably longer than most long-haul flights. The compact, pocket-sized body is built to live in a carry-on or a gym bag.
Who should buy it: frequent flyers, anyone traveling with a partner who wants to share one screen's audio, and gym users whose equipment still has a 3.5mm jack. Who should skip it: anyone hoping to use it with a phone, car stereo or hearing aid, and anyone who wants the adapter to double as a headphone.
• Best for hearing protection → HomeSpot Work Headphones (27dB NRR, OSHA-compliant, passive isolation via triple-flange tips).
• Best for aptX HD listening → HomeSpot Work Headphones if you want the codec in a wearable device; Avantree Relay & SoundJet if you want to feed aptX HD/Adaptive to headphones you already own.
• Best for battery life → Avantree Relay & SoundJet (up to 25 hours vs up to 24 hours; HomeSpot lists 20 hours average).
• Best for sharing audio with a second person → Avantree Relay & SoundJet (two Bluetooth headphones connected at once).
• Best for moving around a large workspace → HomeSpot Work Headphones (Bluetooth 5.4, up to 100 ft / 30 m range).
• Best for travel and gym bags → Avantree Relay & SoundJet (pocket-sized, no cable to a headphone required).
• Best for calls at work → HomeSpot Work Headphones (CVC microphone plus physical button controls).
• Best for a device that works without a paired phone → Avantree Relay & SoundJet (it transmits from any 3.5mm AUX source).
In my opinion, these two don't really compete — they solve opposite problems, so the pick is about your day, not about which is "better." If your noise problem happens at work and you want protection, calls and aptX HD audio in one wearable, I'd buy the HomeSpot Work Headphones; the 27dB NRR, 100 ft range and neckband design are built for exactly that. If your problem is a 3.5mm jack on a plane or a gym machine and you want to use your own headphones — or share with someone — I'd buy the Avantree Relay & SoundJet. Unless you fit the airplane/gym scenario, HomeSpot is the one most people will actually use daily.
which earbuds support aptx hd
The HomeSpot Work Headphones support aptX HD, per their spec sheet, and deliver it when paired with a compatible aptX HD source device. The Avantree Relay & SoundJet also carries aptX HD and aptX Adaptive, but as a transmitter — so it sends that audio to aptX HD-capable headphones you already own rather than being a pair of earbuds itself.
HomeSpot Work Headphones vs Avantree Relay & SoundJet — which should I buy?
No. It works with AirPods, Bose and all Bluetooth headphones, but the aptX HD and aptX Adaptive benefit only applies if your headphones support those codecs. Without them, you'll still get a working Bluetooth link over Bluetooth 5.3, just not the higher-fidelity codec.
No. Avantree states it is not compatible with phones, car stereos or hearing aids. It is designed as a transmitter for a 3.5mm AUX source such as in-flight entertainment or gym equipment. For phone or car use, the HomeSpot Work Headphones pair directly over Bluetooth 5.4 instead.
