BlaidsSoundScore 3.4Grade B

Blaids BlaidsX Pro

The Blaids BlaidsX Pro is a behind-the-ear amplification product that earns a B grade with a SoundScore of 3.4/5 in our lab testing, ranking #4 of 8 devices in the Amplification Product category. Priced at $549, it sits in the premium amplifier tier. This device's standout strength is speech clarity in quiet environments, scoring 3.3/5—a solid result that sits 1.21 points above the category average of 2.11/5. For users who primarily need help hearing conversations in calm settings like home or one-on-one discussions, this represents meaningful benefit over many competing amplifiers. However, the BlaidsX Pro shows limitations in other areas. Speech in noise performance is low at 1.2/5, slightly below the category average. Music streaming scored 0.0/5, falling 1.16 points below the category average—users who want to stream audio from their phone should look elsewhere. Feedback handling is solid in absolute terms at 3.3/5, though this sits below the category average of 4.28/5. The BlaidsX Pro uses disposable batteries and does not offer app-based customization or Bluetooth streaming capabilities. It's best suited for users who prioritize speech understanding in quiet environments and prefer a straightforward, no-frills amplification solution. Those needing robust performance in noisy situations or streaming functionality should consider alternatives like the Sennheiser Conversation Clear Plus, which scored 4.04/5 in our testing.

PhonakSoundScore 5.0Grade A

Phonak Sphere Infinio

The Phonak Sphere Infinio is a premium behind-the-ear prescription hearing aid released in 2024, priced at $4,898. In our lab testing, it earned an A grade with a SoundScore of 5.0/5, placing it at #2 among 39 prescription hearing aids tested—within the top 3% of its category. The standout performance comes in speech clarity. Speech in noise scores an excellent 4.7/5, a remarkable 2.59 points above the category average of 2.11/5. Speech in quiet also impresses at 4.5/5, sitting 1.07 points above average. For anyone who struggles to follow conversations in restaurants, gatherings, or busy environments, this device delivers measurably superior intelligibility compared to most alternatives we've tested. Music streaming quality is strong at 4.0/5, exceeding the category average by 1.24 points—a meaningful advantage for users who value audio fidelity when streaming from phones. However, own-voice comfort is mixed at 2.3/5, falling 0.40 points below the category average, which may affect how natural your own speech sounds. Feedback handling, while solid in absolute terms at 3.6/5, sits 1.12 points below the category average of 4.72/5. The Sphere Infinio is best suited for users prioritizing exceptional speech understanding, particularly in challenging noise environments, and who are willing to invest at the premium tier. Those especially sensitive to own-voice quality or requiring maximum feedback stability may want to compare alternatives like the similarly-priced Oticon Intent or the lower-priced Phonak Audéo EON Sphere.
