Your older car stereo, powered speaker, or home audio system may still sound good even though it lacks Bluetooth. The Anker Soundsync A3352 adds wireless audio through a 3.5mm AUX connection, so you can stream from a phone, tablet, or computer without replacing the equipment you already own. It is compact, supports two paired source devices, and offers up to 12 hours of playtime. Its main limitation is just as important: it receives Bluetooth audio only and cannot send TV or game audio to Bluetooth headphones.
This review helps you decide whether the A3352 fits your connections, calling needs, charging routine, and audio setup. It also explains the product’s current Amazon status, practical setup steps, and the differences between this receiver and transmitter-capable alternatives.
Quick Verdict
Rating: 8/10, recommended with caveats
Best For: Older car stereos, home stereos, powered speakers, and wired headphones with a 3.5mm AUX input.
Bottom Line: The Anker Soundsync A3352 is a simple, compact way to add Bluetooth receiving and hands-free calls to AUX-equipped audio gear. Its receiver-only design and current Amazon availability limit make it less suitable for TV audio, Bluetooth headphones, or buyers who need immediate delivery.
Product Status on Amazon

What Is the Anker Soundsync Bluetooth Receiver and How Does It Work?
The Anker Soundsync A3352 is a small battery-powered Bluetooth receiver for audio equipment that already has a 3.5mm input. Your phone, tablet, or computer sends audio to the A3352 over Bluetooth. The receiver then passes that sound through its AUX connection to your car stereo, powered speaker, home system, or wired headphones.
The device is made for receiving audio from a Bluetooth source. It does not create Bluetooth output for a TV or other wired source. It also cannot pair directly with Bluetooth headphones or Bluetooth speakers because both devices would be waiting to receive a signal.
Bluetooth 5.0, a built-in microphone, physical controls, and dual-device pairing make it more useful than a basic one-button adapter. The compact body is easy to place near a car dashboard, amplifier, speaker input, or headphone cable without taking much room.
Who Should Buy It?
Best For
- Drivers whose car stereo has AUX but lacks built-in Bluetooth audio.
- Owners of older powered speakers, amplifiers, or home stereos with a 3.5mm or RCA line input.
- People who want to use wired headphones without keeping the phone physically attached.
Skip If
- You need transmitter mode for a TV, gaming system, airplane screen, or Bluetooth headphones.
- Your audio system lacks a 3.5mm or compatible RCA input.
- You need a listed low-latency codec for video editing, gaming, or strict lip-sync use.

Listen music wireless: Connect with computer speakers, home stereo systems or other speaker systems via the 3.5 mm or RCA cable, then pair with the Bluetooth audio devices such as smartphones or tablet for streaming music.
Design, Controls, and Build
The A3352 measures about 1.9 by 1.1 by 0.4 inches and weighs about 0.4 ounces without packaging. That size works well in a car because you can position the receiver near the AUX port or clip-free cable area instead of adding a large dashboard accessory.
The multifunction button handles power, play or pause, calls, and pairing. Separate volume controls can also change tracks, which reduces the need to reach for your phone. A status light shows pairing, connection, charging, low-battery, and call states.
The built-in microphone supports hands-free calls, but placement matters. Keep the receiver within reasonable speaking distance and away from vents, loose objects, and noisy surfaces. It is useful for basic calls, but a dedicated car speakerphone may perform better in a loud cabin.
Battery Life and Charging
Anker rates the Soundsync A3352 for up to 12 hours of AUX playtime, with a full charge taking about two hours. That is enough for several commutes, a full workday of background audio, or a long home listening session. Actual runtime can vary with volume, call use, battery age, and connection conditions.
The receiver turns on during charging, so you can keep it powered for long sessions. However, a charging cable in a car can introduce cable clutter or electrical noise in some setups. Start with a full battery when possible, then charge only when needed.
Charging hardware may vary by production revision. Older documentation shows micro USB, while newer package information may show USB-C. Check the current Amazon images and “what’s in the box” details before choosing a cable or spare charger.
Bluetooth Connectivity and Sound
The linked product page lists Bluetooth 5.0 and a range of roughly 30 feet, while the manual lists up to 33 feet in open conditions. Inside a car or room, metal panels, walls, other wireless devices, and the position of your phone can reduce that distance.
For music, podcasts, and audiobooks, the A3352 is designed for normal stereo streaming through the A2DP profile. Your final sound quality depends on the source file, phone volume, AUX cable, amplifier, and speakers. No aptX or dedicated low-latency codec is listed, so this model is better for everyday listening than timing-sensitive TV or gaming use.
Dual pairing lets two phones, tablets, or computers remain connected. It does not mix both audio streams. Pause playback on the first device before starting audio on the second.
Pro Tip: Set your phone near 70% to 85% volume, then use the receiver or stereo to fine-tune loudness. This often gives you better control than running one device at maximum and the other very low.
Setup Tips Before First Use
- Charge the receiver: Fully charge it before the first pairing session.
- Connect the audio cable: Plug the A3352 into your car, speaker, headphones, or stereo AUX input. Use a 3.5mm-to-RCA cable if your home system has red and white line inputs instead of a headphone-style AUX port.
- Select the correct input: Switch the stereo or car system to AUX.
- Turn on pairing: Hold the multifunction button until the device enters pairing mode, then select “Soundsync A3352” in your phone’s Bluetooth menu.
- Balance the volume: Start low, play audio, and raise the phone and stereo volume gradually.
- Test calls safely: Make a stationary test call before relying on the microphone while driving.
For two-device use, pair the first device, place the receiver back into pairing mode, and connect the second. Reconnect the first device from its Bluetooth menu if needed. Only one source can play audio at a time.
How It Performs in Real Use
In an Older Car
The A3352 adds wireless music and call handling when the factory radio has AUX but no Bluetooth streaming. Its small size is convenient, though call clarity depends on receiver placement and road noise. It does not replace Android Auto, Apple CarPlay, or steering-wheel integration.
With a Home Stereo
You can connect it directly to a 3.5mm input or use a 3.5mm-to-RCA cable for many amplifiers and receivers. This gives an older system easy phone streaming without changing the speakers or amplifier. You still control source selection and most volume functions on the stereo.
With Wired Headphones
The receiver can turn standard 3.5mm headphones into a partly wireless setup. The headphones remain connected to the A3352, but your phone can stay in a bag or on a desk. This works best when you do not mind carrying the small receiver and charging another battery.
With Two Source Devices
Dual pairing is useful when you use a work phone for calls and a personal phone or tablet for music. Switching is not fully automatic for simultaneous playback, so pause the active source before starting the other one.
Compatibility, Care, and Safety
Confirm that your playback device accepts analog audio through a 3.5mm AUX input or a compatible RCA line input. A USB port alone does not guarantee audio compatibility because the A3352 sends sound through AUX, not through USB.
Keep the receiver dry and away from liquids, extreme heat, corrosive cleaners, and impacts. Use the supplied or a certified charging cable. When storing it for a long period, keep it in a cool place and recharge it periodically so the battery does not remain deeply discharged.
Do not place the receiver where it blocks driving controls, airbag areas, visibility, or safe cable movement. Pair devices and adjust settings before driving.
Pros and Cons
Pros
- Compact 50 × 29 × 10 mm body fits easily in a car or home setup.
- Up to 12 hours of playtime with about a two-hour charge.
- Dual pairing supports two Bluetooth source devices.
- Physical buttons handle volume, tracks, playback, and calls.
- Includes AUX accessories for common 3.5mm audio connections.
Cons
- Receiver-only design cannot send audio to Bluetooth headphones or speakers.
- No listed aptX or dedicated low-latency codec for strict video synchronization.
- The direct Amazon listing was unavailable at the time of this review, and charging-port revisions may differ.
Is It Worth the Price?
The Anker Soundsync A3352 offers strong value when you want a trusted-brand receiver with physical controls, dual pairing, hands-free calls, and a compact battery-powered design. It can extend the useful life of an older car or home audio system for much less effort than replacing the stereo.
Value depends heavily on availability. Because the direct listing was unavailable during this review, avoid paying an inflated third-party price without comparing newer receivers. It is worth considering if you find normal seller terms and specifically want this compact Anker model. It is not the best fit when you need transmitter mode, modern high-resolution codecs, or a permanently powered adapter.

ACC Wire Required: No ACC = No Power – The blafili CAR requires the red ACC/ignition wire to receive voltage before the unit can turn on. Standard wiring: yellow wire to +12V power, black wire to ground, and red ACC wire to ACC/ignition. If no ACC signal is available, connect both the red ACC wire and yellow +12V power wire to the same +12V power source. If the red ACC wire is left unconnected, the unit will not power on.

How It Compares to Alternatives
The Anker Soundsync A3341 is the better Anker option when you need both transmitter and receiver modes, including TV-to-Bluetooth-headphone use. A COMSOON 3.5mm Bluetooth receiver may suit buyers who want longer advertised battery life and newer call-noise features, while current UGREEN receivers may offer newer codecs or USB-powered designs.
The A3352 makes the most sense when you prefer a very small receiver, simple AUX setup, physical controls, and Anker’s familiar support structure. Compare connection type, codec support, battery life, microphone design, and current seller terms rather than choosing by Bluetooth version alone.

Frequently Asked Questions
Is the Anker Soundsync A3352 a receiver or transmitter?
It is a Bluetooth receiver only. It accepts wireless audio from a phone, tablet, or computer and sends that audio through a 3.5mm AUX connection. It cannot transmit TV audio to Bluetooth headphones.
Will it work with my car stereo?
It should work when your car stereo has a functioning 3.5mm AUX input. Select AUX on the stereo after connecting the receiver. A car with only USB, Bluetooth calling, or a proprietary media port may need a different adapter.
Can I connect it to a home stereo with RCA inputs?
Yes, when you use a 3.5mm-to-RCA cable and connect it to a line-level input such as AUX, CD, or Tape. Do not connect it to a phono input because that input is designed for a turntable signal.
Can it connect directly to Bluetooth headphones or speakers?
No. The A3352 and Bluetooth headphones are both receivers, so they do not send audio to each other. Use the A3352 with wired headphones or a speaker that has an AUX input.
How long does the battery last and charge?
Anker lists up to 12 hours of AUX playtime and about two hours for a full charge. Battery age, volume, calls, and wireless conditions can shorten real runtime.
Can it stay connected to two devices?
Yes. Dual pairing allows two source devices to remain connected, but the receiver plays audio from only one at a time. Pause the first device before starting playback on the second.
Can I use the A3352 while it is charging?
The manual indicates that the receiver switches on during charging and shows a connected-charging status. For the cleanest setup, begin with a full battery and use a certified cable when continuous power is necessary.
Does it use micro USB or USB-C?
Older A3352 documentation shows micro USB, while newer product documentation and package information may show USB-C. Check the live listing images and included-items section for the exact revision being sold.
The Bottom Line
The Anker Soundsync A3352 is a good choice for adding Bluetooth music and basic hands-free calls to a car stereo, home system, powered speaker, or wired headphones with AUX. Choose it for its compact size, 12-hour rated battery, physical controls, and dual pairing. Skip it if you need transmitter mode, low-latency TV audio, direct Bluetooth-headphone pairing, or a product that is clearly available for immediate purchase.
